+### Updating the Tab5 C6 from Modulus
+
+The Tab5 **M Panel > C6 Update** page updates the ESP32-C6 over the internal
+ESP-Hosted SDIO connection. Copy an ESP32-C6 **application image** (`.bin`) to
+the root of a FAT-formatted SD card, insert it, and open the page. Use
+**Refresh SD**, select the file, then **Check image**. Modulus verifies the ESP
+image header and ESP32-C6 chip ID before enabling **Flash C6**.
+
+Flashing never starts automatically. Keep power and the SD card connected while
+the progress bar is active. After successful activation, **Restart Modulus** is
+enabled so the P4 can reboot and reconnect to the updated C6 firmware.
+
+Use an ESP-Hosted slave application image compatible with the host component
+version pinned in `firmware/tab5/dependencies.lock`. Do not use a full-flash,
+merged, bootloader, or partition-table image.
+
+Recovery: if the C6 update is interrupted and SDIO no longer starts, restore a
+complete C6 flash set through the C6 USB bootloader (`bootloader.bin`,
+`partition-table.bin`, `ota_data_initial.bin`, and `network_adapter.bin` at the
+documented offsets). The P4 OTA page cannot repair a C6 that no longer boots far
+enough to provide ESP-Hosted OTA.

+# Modulus Firmware – C6-OTA für Tab5
+
+**Version:** 3.1.0
+**Autor:** D. McLean / BufferRoot
+**Feature-Branch:** `feature/tab5-c6-ota`
+**Plattform:** M5Stack Tab5 (ESP32-P4 + ESP32-C6)
+**Lizenz:** [MIT](LICENSE)
+
+Modulus ist eine CNC-Pendant-Firmware für das M5Stack Tab5. Der ESP32-P4 führt
+Oberfläche und Steuerungslogik aus; der ESP32-C6 stellt WLAN, BLE und ESP-NOW
+über ESP-Hosted/SDIO bereit. Das Pendant ersetzt nicht die Maschinensteuerung
+und nicht den hardwareseitigen Not-Aus.
+
+## Warum es diesen Feature-Branch gibt
+
+Für ein C6-Update war bisher eine separate USB-/Bootloader-Verbindung zum C6
+nötig. Dieser Branch ergänzt im P4-Menü die Seite **C6 Update**. Damit lässt sich
+eine kompatible C6-Anwendungsdatei von der SD-Karte auswählen und über die
+bereits vorhandene ESP-Hosted-SDIO-Verbindung übertragen.
+
+Der vorgesehene Ablauf lautet deshalb **zuerst P4, danach C6**: Zunächst wird
+die P4-Firmware mit dem neuen Updater installiert. Anschließend startet Modulus
+normal und aktualisiert den C6 über **M Panel → C6 Update**. Das Flashen beginnt
+niemals automatisch. Image-Prüfung, ausdrückliche Bestätigung, Fortschrittsbalken
+und Neustart-Schaltfläche sichern den Ablauf ab.
+
+## Architektur in Kurzform
+
+| Ziel | Aufgabe |
+|------|---------|
+| **ESP32-P4** | Tab5-Oberfläche, MPG und Steuerung; enthält den C6-Updater |
+| **ESP32-C6** | WLAN, BLE und ESP-NOW über ESP-Hosted/SDIO |
+| **ESP32-S3** | ESP-NOW-Bridge im Schaltschrank zur CNC-UART |
+| **NanoH2** | Optionaler Zigbee-Koordinator |
+
+## Voraussetzungen
+
+- ESP-IDF 6.0.1 und esptool
+- USB-Verbindung zum Tab5-P4 (Beispiel: `COM5`)
+- FAT32-formatierte SD-Karte für das C6-Update
+- Passende Builds desselben Firmwarestands für P4 und C6
+
+Die COM-Portnummer kann auf deinem Rechner abweichen.
+
+## Empfohlene Flash-Reihenfolge
+
+### 1. ESP32-P4 zuerst flashen
+
+Dieser Feature-Branch muss auf dem P4 laufen, bevor der C6 per SDIO aktualisiert
+werden kann. Baue ihn mit:
+
+```powershell
+.\scripts\build_tab5.ps1
+```
+
+> [!IMPORTANT]
+> Für den Tab5-P4 immer das Build-Skript verwenden. Ein direktes
+> `idf.py build` wendet die nötigen ESP-IDF-6-/ESP-Hosted-Patches nicht an.
+
+Flashe danach den vollständigen P4-Satz aus dem erzeugten Paket:
+
+```powershell
+cd path\to\tab5-p4
+esptool.py --chip esp32p4 -p COM5 --before default-reset --after hard-reset write_flash `
+ --flash-mode dio --flash-freq 40m --flash-size 16MB `
+ 0x2000 bootloader.bin `
+ 0x8000 partition-table.bin `
+ 0x10000 modulus_tab5.bin
+```
+
+Tab5 vollständig aus- und wieder einschalten. Warte auf das normale Dashboard
+und prüfe, ob **M Panel → C6 Update** vorhanden ist.
+
+### 2. C6-Anwendungsdatei erzeugen
+
+Baue die C6-Firmware mit:
+
+```powershell
+.\scripts\build_tab5_c6_modulus.ps1
+```
+
+Die für OTA benötigte Datei ist:
+
+```text
+firmware/tab5-c6/build/network_adapter.bin
+```
+
+Sie darf umbenannt werden, zum Beispiel in
+`modulus-c6-ota-2.12.12.bin`. Entscheidend ist ihr Inhalt, nicht der Dateiname.
+
+### 3. ESP32-C6 über das Tab5 aktualisieren
+
+1. SD-Karte als FAT32 formatieren.
+2. **Nur** `network_adapter.bin` beziehungsweise die umbenannte OTA-Datei in
+ das Stammverzeichnis der SD-Karte kopieren.
+3. SD-Karte in das laufende Tab5 einsetzen.
+4. **M Panel → C6 Update** öffnen.
+5. **Refresh SD** drücken, Datei auswählen und **Check image** drücken.
+6. Prüfen, dass ein ESP32-C6-Application-Image erkannt und akzeptiert wird.
+7. **Flash C6** drücken und die Sicherheitsabfrage bestätigen.
+8. Während des Fortschrittsbalkens weder Strom noch SD-Karte entfernen.
+9. Nach erfolgreicher Aktivierung **Restart Modulus** drücken.
+10. Prüfen, ob Dashboard und C6-/ESP-NOW-Verbindung wieder verfügbar sind.
+
+> [!WARNING]
+> Kein Full-/Merged-Image, Release-ZIP, `bootloader.bin`,
+> `partition-table.bin` oder `ota_data_initial.bin` im OTA-Menü auswählen.
+> Diese Dateien sind für feste Flash-Adressen bestimmt und keine gültigen
+> OTA-Anwendungsimages.
+
+## C6-Wiederherstellung per USB
+
+Dieser Weg ist nur nötig, wenn der C6 nicht mehr weit genug startet, um
+ESP-Hosted/SDIO-OTA anzubieten. Verbinde den C6-Bootloader per USB und flashe
+den vollständigen Satz an seine festen Adressen:
+
+```powershell
+cd path\to\tab5-c6
+esptool.py --chip esp32c6 -p COM6 --before default-reset --after hard-reset write_flash `
+ --flash-mode dio --flash-freq 80m --flash-size 4MB `
+ 0x0 bootloader.bin `
+ 0x8000 partition-table.bin `
+ 0xd000 ota_data_initial.bin `
+ 0x10000 network_adapter.bin
+```
+
+Falls kein Port erscheint, beim Anschließen des C6-USB die **BOOT**-Taste
+gedrückt halten. Danach das Tab5 vollständig neu starten.
+
+## Weitere Firmwareziele
+
+- **S3-Bridge:** verbindet ESP-NOW mit der UART der CNC-Steuerung.
+- **NanoH2:** optionaler Zigbee-Hub; Zigbee-Only-Firmware niemals auf den C6
+ des Tab5 flashen.
+
+Die vollständige Architektur-, Build- und Entwicklerdokumentation befindet
+sich in der [englischen README](README.md).
+
+## Sicherheit
+
+Der Pendant-E-Stop an GPIO16 ist nur eine zusätzliche Softwarefunktion. Er ist
+kein sicherheitsgerichteter Abschaltkreis und kann bei ausgefallener
+Funkverbindung die Maschine nicht stoppen. Der echte Maschinen-Not-Aus bleibt
+immer die primäre Sicherheitseinrichtung.

**One Device, One Software. Real control for any machine — no lag, no brand lock-in, no compromise.**
+## Why this feature branch exists
+
+The ESP32-C6 is the Tab5's wireless coprocessor, but updating it traditionally
+requires a separate USB/bootloader connection. This branch adds a guarded
+**C6 Update** page to the P4 user interface so a compatible C6 application can
+be selected from the Tab5 SD card and transferred through the existing
+ESP-Hosted SDIO link.
+
+The intended maintenance sequence is therefore **P4 first, C6 second**: install
+the P4 firmware that contains the updater, boot Modulus normally, then use
+**M Panel → C6 Update** to update the C6. An image check, an explicit
+confirmation step, a progress display, and a post-update restart button keep
+the operation deliberate; C6 flashing never starts automatically.

-Für ein C6-Update war bisher eine separate USB-/Bootloader-Verbindung zum C6

+Modulus verteilt seine Aufgaben auf mehrere Prozessoren. Für Updates des
+ESP32-C6 im Tab5 und der ESP32-S3-Bridge war bisher jeweils ein separater
+USB-/Bootloader-Zugang nötig. Dieser Branch ergänzt **C6 Update** und
+**S3 Update** im M Panel. C6-App-Images werden intern über ESP-Hosted/SDIO
+übertragen, S3-App-Images per ESP-NOW. Als Quelle funktionieren ein
+FAT-formatierter USB-A-Stick oder eine microSD-Karte.
-Der vorgesehene Ablauf lautet deshalb **zuerst P4, danach C6**: Zunächst wird
-die P4-Firmware mit dem neuen Updater installiert. Anschließend startet Modulus
-normal und aktualisiert den C6 über **M Panel → C6 Update**. Das Flashen beginnt

+Freigabe und starten das Ziel erst auf Tastendruck neu. Ein C6-Image kann nicht
+versehentlich über die S3-Seite geflasht werden und umgekehrt. Beide OTA-Wege

-## Why this feature branch exists
+## Why this OTA feature branch exists
-The ESP32-C6 is the Tab5's wireless coprocessor, but updating it traditionally
-requires a separate USB/bootloader connection. This branch adds a guarded
-**C6 Update** page to the P4 user interface so a compatible C6 application can
-be selected from the Tab5 SD card and transferred through the existing
-ESP-Hosted SDIO link.
+Modulus runs across multiple processors, but the Tab5's ESP32-C6 radio and the
+cabinet ESP32-S3 bridge traditionally required separate USB/bootloader access.
+This branch adds guarded **C6 Update** and **S3 Update** pages to M Panel. C6
+application images travel over the internal ESP-Hosted/SDIO link; S3
+application images travel over ESP-NOW. Both pages read a FAT-formatted USB-A
+drive or microSD card and reject images built for the wrong chip.
-The intended maintenance sequence is therefore **P4 first, C6 second**: install
-the P4 firmware that contains the updater, boot Modulus normally, then use
-**M Panel → C6 Update** to update the C6. An image check, an explicit
-confirmation step, a progress display, and a post-update restart button keep
-the operation deliberate; C6 flashing never starts automatically.
+The maintenance sequence is **P4 first, then C6 and/or S3**: install the P4
+firmware containing the OTA UI, boot Modulus normally, and select the matching
+updater. The XIAO ESP32-S3 needs the OTA-capable full image once over USB; later
+updates use only its application image. Image inspection, explicit arming,
+progress feedback, and a separate restart action keep every write deliberate.
+Nothing is flashed automatically.
+
+The complete C6 and XIAO S3 OTA paths, including an S3 update from USB-A and a
+successful boot from its second OTA slot, have been verified on real hardware.

+**M Panel → S3 Update**. Select the file, press **Check S3 image**, then
+**Flash S3**, and finally **Restart S3**. Reinstalling the same app image is a
+valid first OTA test.
+
+Keep the CNC idle and do not remove power or the source drive during transfer. The
+S3 page accepts only an ESP32-S3 application image; the C6 page accepts only an
+ESP32-C6 application image. A merged/full-flash image is intentionally rejected
+by both OTA pages and must only be written over USB at offset `0x0`.
+
+Both **C6 Update** and **S3 Update** scan the Tab5 USB-A mass-storage volume and
+the microSD card. Results are prefixed with `USB:` or `SD:`. USB-A is the
+recommended maintenance path when the installed enclosure does not expose the
+microSD slot. Insert the FAT-formatted stick, wait for it to mount, and press
+**Refresh drives**.
+
+If the serial command menu was missed during boot, press Enter on an empty line
+to print it again (`uartping`, configuration commands, and diagnostics).

Enable **EXT5V** for Grove/H2 power. Unzip `modulus-nanoh2-v3.1.0.zip`, hold **BUTTON** on the Stamp, then:

# Modulus Firmware – OTA für Tab5
-**Version:** 3.1.0
+**Version:** 3.1.3-ota
**Autor:** D. McLean / BufferRoot
**Feature-Branch:** `feature/tab5-ota`
**Plattform:** M5Stack Tab5 (ESP32-P4 + ESP32-C6)

| **ESP32-S3** | ESP-NOW-Bridge im Schaltschrank zur CNC-UART |
| **NanoH2** | Optionaler Zigbee-Koordinator |
-## Voraussetzungen
+## Fertige Full-Images für v3.1.3-ota
-- ESP-IDF 6.0.1 und esptool
-- USB-Verbindung zum Tab5-P4 (Beispiel: `COM5`)
-- FAT32-formatierter USB-Stick
-- Passende Builds für P4 sowie das jeweilige C6- oder S3-Ziel
+Die drei BINs direkt aus [Release v3.1.3-ota](https://github.com/fellpower/Modulus-Firmware/releases/tag/v3.1.3-ota)
+herunterladen. Ein lokaler Neubau oder Entpacken ist zum Flashen nicht nötig.
-Die COM-Portnummer kann auf deinem Rechner abweichen.
+| Ziel | Einzelne BIN | Flash-Adresse |
+|------|--------------|---------------|
+| Tab5 P4 | `modulus-tab5-p4-full-v3.1.3-ota.bin` | `0x0` |
+| Tab5 C6 | `modulus-tab5-c6-full-v3.1.3-ota.bin` | `0x0` |
+| XIAO ESP32-S3 | `modulus-xiao-s3-full-v3.1.3-ota.bin` | `0x0` |
-## Empfohlene Flash-Reihenfolge
+Die Images enthalten Bootloader, Partitionstabelle, gegebenenfalls OTA-Startdaten
+und Anwendung aus den vorhandenen Release-Einzeldateien. Der P4-Bootloader liegt
+innerhalb der BIN weiterhin bei `0x2000`, die XIAO-S3-App bei `0x20000`.
+**Die vollständige BIN wird trotzdem immer bei `0x0` geschrieben.**
+Lücken sind mit `0xFF` gefüllt. Das Schreiben kann Einstellungen/NVS und die
+OTA-Auswahl im beschriebenen Adressbereich zurücksetzen. Für spätere C6-/S3-Updates
+sind deshalb die App-only-Dateien vorgesehen.
-### 1. ESP32-P4 zuerst flashen
+## Flashen per USB
-Dieser Feature-Branch muss auf dem P4 laufen, bevor C6 oder S3 über das Tab5
-aktualisiert werden können. Baue ihn mit:
+- Python und esptool installieren: `python -m pip install esptool==5.3.1`.
+- USB-Datenkabel verwenden, Terminal im Downloadordner öffnen.
+- COM-Port im Geräte-Manager prüfen; `COM5`, `COM6` und `COM8` sind Beispiele.
+- Den USB-Bootloader des richtigen Chips verbinden. Der P4-USB-Anschluss flasht
+ den C6 nicht direkt. Bei Bedarf den jeweiligen BOOT-/Downloadmodus aktivieren.
+- Reihenfolge: P4 zuerst; C6 bei kabelgebundener Installation/Wiederherstellung;
+ danach XIAO S3 einmalig für OTA vorbereiten.
+- Nur den Befehl für das gerade angeschlossene Ziel ausführen:
```powershell
-.\scripts\build_tab5.ps1
+python -m esptool --chip esp32p4 -p COM5 write-flash --flash-mode dio --flash-freq 40m --flash-size 16MB 0x0 modulus-tab5-p4-full-v3.1.3-ota.bin
+python -m esptool --chip esp32c6 -p COM6 write-flash --flash-mode dio --flash-freq 80m --flash-size 4MB 0x0 modulus-tab5-c6-full-v3.1.3-ota.bin
+python -m esptool --chip esp32s3 -p COM8 write-flash --flash-mode dio --flash-freq 80m --flash-size 8MB 0x0 modulus-xiao-s3-full-v3.1.3-ota.bin
```
-> [!IMPORTANT]
-> Für den Tab5-P4 immer das Build-Skript verwenden. Ein direktes
-> `idf.py build` wendet die nötigen ESP-IDF-6-/ESP-Hosted-Patches nicht an.
-
-Flashe danach den vollständigen P4-Satz aus dem erzeugten Paket:
-
-```powershell
-cd path\to\tab5-p4
-esptool.py --chip esp32p4 -p COM5 --before default-reset --after hard-reset write_flash `
- --flash-mode dio --flash-freq 40m --flash-size 16MB `
- 0x2000 bootloader.bin `
- 0x8000 partition-table.bin `
- 0x10000 modulus_tab5.bin
-```
-
-Tab5 vollständig aus- und wieder einschalten. Warte auf das normale Dashboard
-und prüfe, ob **M Panel → C6 Update** und **M Panel → S3 Update** vorhanden sind.
-
-### 2. C6-Anwendungsdatei erzeugen
-
-Baue die C6-Firmware mit:
-
-```powershell
-.\scripts\build_tab5_c6_modulus.ps1
-```
-
-Die für OTA benötigte Datei ist:
-
-```text
-firmware/tab5-c6/build/network_adapter.bin
-```
-
-Sie darf umbenannt werden, zum Beispiel in
-`modulus-c6-ota-2.12.12.bin`. Entscheidend ist ihr Inhalt, nicht der Dateiname.
-
-### 3. ESP32-C6 über das Tab5 aktualisieren
-
-1. USB-Stick als FAT32 formatieren.
-2. **Nur** `network_adapter.bin` beziehungsweise die umbenannte OTA-Datei in
- das Stammverzeichnis des Datenträgers kopieren.
-3. USB-Stick in den USB-A-Port des laufenden Tab5 einsetzen.
-4. **M Panel → C6 Update** öffnen.
-5. **Refresh USB** drücken, die `USB:`-Datei auswählen und **Check image** drücken.
-6. Prüfen, dass ein ESP32-C6-Application-Image erkannt und akzeptiert wird.
-7. **Flash C6** drücken und die Sicherheitsabfrage bestätigen.
-8. Während des Fortschrittsbalkens weder Strom noch Quelldatenträger entfernen.
-9. Nach erfolgreicher Aktivierung den automatischen Drei-Sekunden-Countdown
- abwarten. Das Tab5 startet selbstständig neu.
-10. Prüfen, ob Dashboard und C6-/ESP-NOW-Verbindung wieder verfügbar sind.
-
-> [!WARNING]
-> Kein Full-/Merged-Image, Release-ZIP, `bootloader.bin`,
-> `partition-table.bin` oder `ota_data_initial.bin` im OTA-Menü auswählen.
-> Diese Dateien sind für feste Flash-Adressen bestimmt und keine gültigen
-> OTA-Anwendungsimages.
-
-## C6-Wiederherstellung per USB
-
-Dieser Weg ist nur nötig, wenn der C6 nicht mehr weit genug startet, um
-ESP-Hosted/SDIO-OTA anzubieten. Verbinde den C6-Bootloader per USB und flashe
-den vollständigen Satz an seine festen Adressen:
-
-```powershell
-cd path\to\tab5-c6
-esptool.py --chip esp32c6 -p COM6 --before default-reset --after hard-reset write_flash `
- --flash-mode dio --flash-freq 80m --flash-size 4MB `
- 0x0 bootloader.bin `
- 0x8000 partition-table.bin `
- 0xd000 ota_data_initial.bin `
- 0x10000 network_adapter.bin
-```
-
-Falls kein Port erscheint, beim Anschließen des C6-USB die **BOOT**-Taste
-gedrückt halten. Danach das Tab5 vollständig neu starten.
-
-## Weitere Firmwareziele
-
-- **S3-Bridge:** verbindet ESP-NOW mit der UART der CNC-Steuerung.
-- **NanoH2:** optionaler Zigbee-Hub; Zigbee-Only-Firmware niemals auf den C6
- des Tab5 flashen.
-
-### S3-OTA auf einem XIAO ESP32-S3 aktivieren und testen
-
-Für OTA braucht der S3 einmalig die neue Dual-Slot-Partitionstabelle und den
-OTA-Empfänger. Das vollständige Image wird einmal per USB bei Offset `0x0`
-installiert:
+Im grafischen Flashtool ebenfalls genau eine BIN bei `0x0` auswählen und
+Chip/Flash-Einstellungen passend setzen. Verifikation abwarten, dann neu starten.
+Ein zusätzliches `erase-flash` gehört nicht zu diesem Ablauf.
+Das bisherige `modulus-xiao-s3-first-flash-for-ota-v3.1.3-ota.bin` ist mit dem
+neuen XIAO-Full-Image inhaltsgleich. Nicht mit dem generischen S3-Bridge-Paket verwechseln.
+
+## Spätere Updates über USB-Stick und OTA
+
+- P4 normal starten und **M Panel → C6 Update / S3 Update** prüfen.
+- Passende Release-Datei herunterladen:
+ `modulus-tab5-c6-ota-app-v3.1.3-ota.bin` oder
+ `modulus-xiao-s3-ota-app-v3.1.3-ota.bin`.
+- Nur die App-BIN ins Stammverzeichnis eines FAT32-Sticks kopieren.
+- Stick in USB-A des Tab5 stecken; microSD wird im OTA-Menü nicht angeboten.
+- Passende Update-Seite öffnen, **Refresh USB**, Datei auswählen.
+- **Check image** beim C6 beziehungsweise **Check S3 image** beim S3 drücken.
+- **Flash C6** beziehungsweise **Flash S3** bestätigen. CNC im Leerlauf lassen;
+ Stromversorgung und Stick während des Updates nicht entfernen.
+- Nach C6-Aktivierung startet der P4 nach drei Sekunden automatisch neu.
+- Nach erfolgreicher S3-Prüfung **Restart S3** drücken.
+- Dashboard und ESP-NOW-Verbindung prüfen. Falls Einstellungen zurückgesetzt
+ wurden, S3-MAC und passenden Funkkanal unter **Settings → Wireless** neu setzen.
+
+**Full-Images gehören ausschließlich zum kabelgebundenen Flash bei `0x0`, niemals
+ins OTA-Menü.** Der XIAO braucht die vollständige USB-Erstinstallation einmalig.
+Startet der C6 nicht mehr oder antwortet nicht über SDIO, das C6-Full-Image über
+seinen USB-Bootloader wiederherstellen.
+
+## Full-Images ohne Neubau reproduzieren
+
+Aus dem Release `MANIFEST.json` sowie die ZIPs für `tab5-p4`, `tab5-c6` und
+`s3-xiao` herunterladen. Manifest in `dist/flash-images/v3.1.3-ota-source/` ablegen
+und die ZIPs darunter mit ihren Zielordnern und `flasher_args.json` entpacken.
```powershell
-python -m esptool --chip esp32s3 -p COM8 erase-flash
-python -m esptool --chip esp32s3 -p COM8 write-flash 0x0 modulus-xiao-s3-bridge-first-flash-for-ota.bin
+.\scripts\package_flash_images.ps1 -Version 3.1.3-ota
```
-Falls durch das Löschen die Einstellungen verloren gingen, anschließend die
-S3-MAC-Adresse und den ESP-NOW-Kanal unter **Settings → Wireless** erneut
-eintragen. Danach nur `modulus-xiao-s3-bridge-ota-app.bin` in das Stammverzeichnis
-eines FAT32-formatierten USB-Sticks kopieren, diesen in USB-A einsetzen und
-**M Panel → S3 Update** öffnen. Datei auswählen,
-**Check S3 image**, **Flash S3** und nach erfolgreicher Prüfung **Restart S3**
-drücken. Für den ersten Test darf dasselbe App-Image noch einmal per OTA
-installiert werden.
-
-Währenddessen muss die CNC im Leerlauf bleiben; Stromversorgung und das
-Quelllaufwerk nicht entfernen. Die S3-Seite akzeptiert ausschließlich ESP32-S3-App-Images,
-die C6-Seite ausschließlich ESP32-C6-App-Images. Vollständige/zusammengeführte
-Images werden von beiden OTA-Seiten absichtlich abgewiesen und gehören nur per
-USB an Offset `0x0`.
-
-Sowohl **C6 Update** als auch **S3 Update** durchsuchen ausschließlich das
-Stammverzeichnis des USB-A-Massenspeichers. Treffer werden mit `USB:`
-gekennzeichnet. FAT32-formatierten Stick einstecken, kurz auf das Einbinden
-warten und **Refresh USB** drücken. Die microSD-Karte wird bewusst nicht als
-OTA-Quelle angeboten; so bleibt die Wartung eindeutig und funktioniert auch
-mit Gehäusen, die den Kartenslot verdecken.
-
-Falls das serielle Befehlsmenü beim Start nicht sichtbar war, eine leere
-Eingabe mit Enter senden. Das Menü mit `uartping`, Konfiguration und Diagnose
-wird dann erneut ausgegeben.
-
-Die vollständige Architektur-, Build- und Entwicklerdokumentation befindet
-sich in der [englischen README](README.md).
+Das Skript prüft Größe und SHA256 jeder Eingabedatei gegen das Release-Manifest
+und übernimmt die Flash-Adressen aus `flasher_args.json`. Es führt ausschließlich
+vorhandene BINs zusammen. Ausgabe: drei Full-BINs, `SHA256SUMS-full.txt` und
+`FLASH-full.md` unter `dist/flash-images/v3.1.3-ota-full/`.
+Mit `-SourceRoot` und `-OutRoot` lassen sich andere Ordner angeben; bereits
+vorhandene Ausgabe-BINs werden nicht überschrieben. Die Images reichen bis zum
+Ende der enthaltenen Anwendung, nicht bis zum Ende des gesamten Flash-Speichers.
+[Prüfsummen der drei Full-Images](FULL-IMAGES-v3.1.3-ota.sha256).
+
+[Deutsche stichpunktartige Videoanleitung](VIDEOANLEITUNG.de.md).
+Weitere Architektur- und Build-Informationen stehen in der [englischen README](README.md).
+NanoH2 und generische S3-Bridge bleiben separate Release-Pakete mit eigener `FLASH.md`.

+These combine the released bootloader, partition table, initial OTA data (C6/S3)
+and application. The P4 bootloader remains at `0x2000` inside its full image;
+the XIAO S3 application remains at `0x20000`. Always flash the **full BIN at `0x0`**.
+Unused gaps are filled with `0xFF`; writing a full image can reset NVS/settings
+and OTA selection within its address range. Use app-only OTA for later C6/S3 updates.
-### What you need
+### USB installation / recovery
-1. [esptool](https://docs.espressif.com/projects/esptool/) (`pip install esptool`) **or** ESP-IDF 6 `idf.py` / `python -m esptool`
-2. USB cables + drivers for each chip
-3. Unzip each package into its own folder (commands below assume you `cd` into that folder)
-
-**Recommended order for this feature branch:** P4 → C6 through **C6 Update** →
-one-time S3 USB first-flash → later S3 images through **S3 Update** → NanoH2
-(optional). The separate C6 USB procedure is a recovery path. Keep the machine
-E-Stop in reach.
-
-COM ports on your PC may differ — change `-p COMx` to match Device Manager.
-
-### 1. Tab5 P4 (main pendant and OTA updaters)
-
-The P4 must contain this feature branch before it can update the C6 or S3. Build this
-branch with `scripts/build_tab5.ps1`, or use a P4 package produced from this
-branch. Then flash its complete P4 set:
-
-```powershell
-cd path\to\tab5-p4
-esptool.py --chip esp32p4 -p COM5 --before default-reset --after hard-reset write_flash `
- --flash-mode dio --flash-freq 40m --flash-size 16MB `
- 0x2000 bootloader.bin `
- 0x8000 partition-table.bin `
- 0x10000 modulus_tab5.bin
-```
-
-Power-cycle the Tab5 and wait for the normal Modulus dashboard. Confirm that
-**M Panel → C6 Update** and **M Panel → S3 Update** are present.
-
-### 2. Tab5 C6 through SDIO OTA (normal method)
-
-Build the C6 application with `scripts/build_tab5_c6_modulus.ps1`. The file to
-copy is:
-
-```text
-firmware/tab5-c6/build/network_adapter.bin
-```
-
-It may be renamed to a descriptive name such as
-`modulus-c6-ota-2.12.12.bin`; renaming does not change its contents.
-
-1. Format a USB drive as FAT32.
-2. Copy **only the C6 application image** (`network_adapter.bin`, or its renamed
- equivalent) to the drive root.
-3. Insert the USB drive into the running Tab5 USB-A port.
-4. Open **M Panel → C6 Update**.
-5. Select **Refresh USB**, choose the `USB:` file, and select **Check image**.
-6. Verify that the screen identifies an ESP32-C6 application and accepts its
- compatibility check.
-7. Select **Flash C6** and confirm the warning. Do not remove power or the
- source drive while the progress bar is moving.
-8. After activation succeeds, wait for the automatic three-second countdown.
- Modulus restarts itself to resynchronize with the C6. Confirm that the
- dashboard returns and the C6/ESP-NOW connection is available.
-
-> [!WARNING]
-> Do **not** put a merged/full-flash image, release ZIP, `bootloader.bin`,
-> `partition-table.bin`, or `ota_data_initial.bin` into the OTA updater. Those
-> files belong to fixed flash offsets and are not valid OTA application images.
-
-### C6 USB recovery (only if SDIO OTA cannot start)
-
-Use this only if the C6 no longer boots far enough for ESP-Hosted/SDIO OTA.
-Unzip the complete C6 flash package, connect the C6 USB bootloader, then run:
-
-```powershell
-cd path\to\tab5-c6
-esptool.py --chip esp32c6 -p COM6 --before default-reset --after hard-reset write_flash `
- --flash-mode dio --flash-freq 80m --flash-size 4MB `
- 0x0 bootloader.bin `
- 0x8000 partition-table.bin `
- 0xd000 ota_data_initial.bin `
- 0x10000 network_adapter.bin
-```
-
-If the port never appears, hold **BOOT** on the C6 while connecting USB. After
-recovery, power-cycle the Tab5.
-
-### 3. ESP32-S3 bridge (cabinet)
-
-Unzip `modulus-s3-bridge-v3.1.0.zip`, then:
-
-```powershell
-cd path\to\s3-bridge
-esptool.py --chip esp32s3 -p COM8 --before default-reset --after hard-reset write_flash `
- --flash-mode dio --flash-freq 80m --flash-size 8MB `
- 0x0 bootloader.bin `
- 0x8000 partition-table.bin `
- 0x10000 s3_espnow_uart_bridge.bin
-```
-
-Wire S3 UART to your CNC (grblHAL) serial. On the Tab5: **Settings → Wireless → ESP-NOW → enter S3 MAC**, lock channel **1 / 6 / 11**.
-
-#### Enabling and testing S3 OTA on a XIAO ESP32-S3
-
-S3 OTA requires the new dual-slot partition table and receiver. Install it once
-over USB with `modulus-xiao-s3-bridge-first-flash-for-ota.bin` at offset `0x0`:
+Install esptool with `python -m pip install esptool==5.3.1`. Open a terminal in
+the download folder. Replace the example COM ports with the actual target ports.
+Use a USB data cable and connect the correct processor's USB bootloader: the
+Tab5 P4 port does not directly flash the C6. If necessary, enter the target's
+BOOT/download mode before connecting. Flash P4 first, then C6 if recovery or a
+wired installation is needed, then XIAO S3.
```powershell
-python -m esptool --chip esp32s3 -p COM8 erase-flash
-python -m esptool --chip esp32s3 -p COM8 write-flash 0x0 modulus-xiao-s3-bridge-first-flash-for-ota.bin
+python -m esptool --chip esp32p4 -p COM5 write-flash --flash-mode dio --flash-freq 40m --flash-size 16MB 0x0 modulus-tab5-p4-full-v3.1.3-ota.bin
+python -m esptool --chip esp32c6 -p COM6 write-flash --flash-mode dio --flash-freq 80m --flash-size 4MB 0x0 modulus-tab5-c6-full-v3.1.3-ota.bin
+python -m esptool --chip esp32s3 -p COM8 write-flash --flash-mode dio --flash-freq 80m --flash-size 8MB 0x0 modulus-xiao-s3-full-v3.1.3-ota.bin
```
-Re-enter the S3 MAC and ESP-NOW channel in **Settings → Wireless** if the erase
-removed the saved peer configuration. Copy only
-`modulus-xiao-s3-bridge-ota-app.bin` to the root of a FAT-formatted USB drive,
-insert it into the Tab5 USB-A port, then open
-**M Panel → S3 Update**. Select the file, press **Check S3 image**, then
-**Flash S3**, and finally **Restart S3**. Reinstalling the same app image is a
-valid first OTA test.
-
-Keep the CNC idle and do not remove power or the source drive during transfer. The
-S3 page accepts only an ESP32-S3 application image; the C6 page accepts only an
-ESP32-C6 application image. A merged/full-flash image is intentionally rejected
-by both OTA pages and must only be written over USB at offset `0x0`.
-
-Both **C6 Update** and **S3 Update** scan only the root of the Tab5 USB-A
-mass-storage volume. Results are prefixed with `USB:`. Insert the FAT-formatted
-stick, wait for it to mount, and press **Refresh USB**. The microSD card is not
-offered as an OTA source; this keeps firmware maintenance clear and usable with
-installed enclosures that do not expose the card slot.
-
-If the serial command menu was missed during boot, press Enter on an empty line
-to print it again (`uartping`, configuration commands, and diagnostics).
-
-### 4. NanoH2 (Zigbee hub, optional)
-
-Enable **EXT5V** for Grove/H2 power. Unzip `modulus-nanoh2-v3.1.0.zip`, hold **BUTTON** on the Stamp, then:
+Run only the command matching the connected chip. A GUI flasher likewise needs
+one file, address `0x0`, and the matching chip/settings. Wait for verification,
+then restart the board. A separate `erase-flash` is not part of this procedure.
+The older `modulus-xiao-s3-first-flash-for-ota-v3.1.3-ota.bin` is equivalent to
+the new XIAO full image. This XIAO image is not the generic S3 bridge package.
+
+### Later C6/S3 updates through Tab5
+
+1. Boot the P4 and confirm **M Panel → C6 Update / S3 Update** are available.
+2. Download `modulus-tab5-c6-ota-app-v3.1.3-ota.bin` or
+ `modulus-xiao-s3-ota-app-v3.1.3-ota.bin` from the same release.
+3. Copy the matching **app-only** BIN to the root of a FAT32 USB drive and insert
+ it into the Tab5 USB-A port. microSD is not an OTA source.
+4. Open the matching update page, press **Refresh USB**, select the file and
+ **Check image** (C6) / **Check S3 image** (S3).
+5. Confirm **Flash C6** / **Flash S3**. Keep the machine idle and power/stick connected.
+6. C6 activation restarts the P4 automatically after three seconds. For S3,
+ select **Restart S3** after successful verification.
+
+Never select a full BIN, bootloader, partition table, OTA-data file or ZIP in
+an OTA menu. The XIAO needs its USB full-image installation once before S3 OTA.
+If C6 cannot boot or answer over SDIO, use the C6 USB full image above.
+
+After flashing, check the dashboard and ESP-NOW connection. Set the S3 MAC and
+matching channel under **Settings → Wireless** again if settings were reset.
+NanoH2 and generic S3 packages remain available separately in the release;
+follow their included `FLASH.md`.
+
+### Reproduce the full images without rebuilding
+
+Download `MANIFEST.json` and the three release ZIPs
+`modulus-tab5-p4-v3.1.3-ota.zip`, `modulus-tab5-c6-v3.1.3-ota.zip`, and
+`modulus-s3-xiao-v3.1.3-ota.zip`. Place the manifest in
+`dist/flash-images/v3.1.3-ota-source/` and extract each ZIP below that directory,
+retaining its target folder and `flasher_args.json`.
```powershell

+The script validates input sizes and SHA256 against the release manifest and
+uses the recorded flash offsets. It only merges existing bytes with esptool;
+it never builds firmware or falls back to local build directories. It produces
+exactly the three full BINs, `SHA256SUMS-full.txt`, and `FLASH-full.md` under
+`dist/flash-images/v3.1.3-ota-full/`. Use `-SourceRoot` and `-OutRoot` to change
+folders; existing output BINs are rejected. These files are not padded to the
+entire flash-chip capacity. Compare hashes with the [recorded full-image checksums](FULL-IMAGES-v3.1.3-ota.sha256).

+# Videoanleitung: Modulus v3.1.3-ota installieren
+
+- **Einstieg / Ziel zeigen**
+ - Tab5 und XIAO ESP32-S3 ins Bild nehmen.
+ - „Wir installieren die vorhandene Release-Firmware ohne lokalen Neubau.“
+ - „Pro Chip brauchen wir genau eine Full-BIN. Flash-Adresse: immer 0x0.“
+- **Download zeigen**
+ - https://github.com/fellpower/Modulus-Firmware/releases/tag/v3.1.3-ota öffnen.
+ - `modulus-tab5-p4-full-v3.1.3-ota.bin` herunterladen.
+ - `modulus-tab5-c6-full-v3.1.3-ota.bin` herunterladen.
+ - `modulus-xiao-s3-full-v3.1.3-ota.bin` herunterladen.
+ - „Full-BINs sind für USB-Erstinstallation oder Wiederherstellung. App-only-BINs sind für spätere OTA-Updates.“
+- **Vorbereitung zeigen**
+ - Maschine stillsetzen; Hardware-Not-Aus erreichbar halten.
+ - Vorhandene Verbindungsdaten, S3-MAC und Funkkanal notieren: Full-Images können Einstellungen und OTA-Auswahl zurücksetzen.
+ - USB-Datenkabel verwenden, tatsächlichen COM-Port im Geräte-Manager zeigen.
+ - `python -m pip install esptool==5.3.1` ausführen; Terminal im Downloadordner öffnen.
+- **P4 zuerst flashen**
+ - Tab5-P4 per USB verbinden; bei Bedarf Downloadmodus aktivieren.
+ - P4-Befehl aus `README.de.md` zeigen und den tatsächlichen COM-Port einsetzen.
+ - Dateiname und `0x0` hervorheben; nur diesen einen Befehl starten.
+ - „Die richtige interne Bootloader-Adresse ist bereits im Full-Image berücksichtigt.“
+ - Verifikation abwarten, Tab5 neu starten und C6-/S3-Update-Menüs zeigen.
+- **C6 per USB installieren oder wiederherstellen**
+ - „Bei funktionierendem SDIO ist auch das App-only-Update über das Tab5 möglich.“
+ - Für den kabelgebundenen Weg den C6-USB-Bootloader verbinden; bei Bedarf BOOT beim Anschließen halten.
+ - „Der P4-USB-Port flasht den C6 nicht direkt.“
+ - C6-Befehl aus `README.de.md` zeigen: richtiger Port, C6-Full-BIN, Adresse `0x0`.
+ - Verifikation abwarten und Tab5 neu starten.
+- **XIAO ESP32-S3 einmalig vorbereiten**
+ - XIAO per USB verbinden; bei Bedarf BOOT-/Downloadmodus verwenden.
+ - XIAO-S3-Befehl aus `README.de.md` zeigen: richtiger Port, XIAO-Full-BIN, Adresse `0x0`.
+ - „Diese BIN enthält die Dual-Slot-Partitionstabelle und den OTA-Empfänger.“
+ - Verifikation abwarten, XIAO neu starten; kein zusätzlicher Erase-Befehl nötig.
+- **Optional: grafisches Flashtool zeigen**
+ - Richtigen Chip und COM-Port auswählen.
+ - Eine Dateizeile aktivieren, passende Full-BIN wählen, Adresse `0x0` setzen.
+ - Flash-Einstellungen aus dem jeweiligen README-Befehl übernehmen.
+- **Späteres OTA-Update demonstrieren**
+ - Passende `modulus-tab5-c6-ota-app-v3.1.3-ota.bin` oder `modulus-xiao-s3-ota-app-v3.1.3-ota.bin` herunterladen.
+ - App-BIN ins Stammverzeichnis eines FAT32-Sticks kopieren und in Tab5 USB-A stecken.
+ - M Panel → C6 Update oder S3 Update → Refresh USB → Datei wählen.
+ - Check image / Check S3 image zeigen; anschließend Flash C6 / Flash S3 bestätigen.
+ - Strom und Stick angeschlossen lassen.
+ - C6: automatischen P4-Neustart nach drei Sekunden abwarten.
+ - S3: nach erfolgreicher Prüfung Restart S3 drücken.
+ - „Full-BINs niemals im OTA-Menü auswählen. microSD ist hier keine Updatequelle.“
+- **Abschluss / Funktion prüfen**
+ - Dashboard und ESP-NOW-Verbindungsstatus zeigen.
+ - Bei Bedarf S3-MAC und passenden Kanal unter Settings → Wireless erneut eintragen.
+ - „Drei Chips, drei Full-Images, beim kabelgebundenen Flash immer eine BIN an 0x0.“

neuen XIAO-Full-Image inhaltsgleich. Nicht mit dem generischen S3-Bridge-Paket verwechseln.
+## C6-Kompatibilität in nachfolgenden Quellcode-Builds
+
+Der Branch fragt die **laufende C6-Version unmittelbar vor dem Schreiben** ab.
+Unter 2.6.0 (auch 1.4.1) aktiviert `OTAEnd` das Image und plant den C6-Neustart;
+ein zusätzliches `OTAActivate` entfällt. Der P4 wartet acht Sekunden bis zu seinem
+Neustart. Ab 2.6.0 wird explizit aktiviert, danach startet der P4 wie bisher nach
+drei Sekunden neu. Bei unbekannter oder nicht lesbarer Version wird nichts geschrieben.
+Eine funktionierende ESP-Hosted-Verbindung und geeignete C6-OTA-Partition bleiben
+nötig. Eine verlorene Abschluss-/Aktivierungsantwort wird als unbestätigter Zustand
+gemeldet, nicht als sicher ausgebliebene Aktivierung.
+
+**Diese Änderung gilt bisher nur für den Quellcode. Die Release-BINs v3.1.3-ota
+wurden nicht neu gebaut und behalten den bisherigen Ablauf.**
+Regressionstest: `python scripts/test_c6_ota.py` (benötigt Zig).
+Der Hardwaretest mit Factory-Firmware 1.4.1 steht noch aus.
+

The older `modulus-xiao-s3-first-flash-for-ota-v3.1.3-ota.bin` is equivalent to
the new XIAO full image. This XIAO image is not the generic S3 bridge package.
+### C6 compatibility in subsequent source builds
+
+The branch queries the **running C6 firmware immediately before writing**.
+Below 2.6.0 (including 1.4.1), legacy `OTAEnd` activates the image and schedules
+the C6 reboot; no `OTAActivate` is sent. The P4 waits eight seconds before
+restarting. From 2.6.0 onward, explicit activation is followed by the existing
+three-second P4 restart delay. Unknown/unreadable versions stop before any write.
+A working ESP-Hosted connection and suitable C6 OTA partition remain necessary.
+A lost completion/activation response is reported as uncertain, not as proof
+that activation did not happen.
+
+**This change is source-only: existing v3.1.3-ota release BINs have not been
+rebuilt and retain the previous behavior.** Run the host regression test with
+`python scripts/test_c6_ota.py` (requires Zig). Hardware validation with factory
+1.4.1 is still required.

+# C6-Legacy-OTA mit Factory-Version 1.4.1 testen
+
+Dieser Test benötigt eine **neu gebaute P4-Firmware ab Commit 69ca844** auf
+`feature/tab5-ota`. Die vorhandenen Release-BINs v3.1.3-ota enthalten den Fix
+nicht, auch nach Ergänzung der Full-Images im ZIP. Die nachfolgenden Schritte
+beschreiben den Hardwaretest; er wurde noch nicht durchgeführt.
+
+## Vorbereitung
+
+- CNC stillsetzen. Verbindungsdaten notieren und einen Wiederherstellungsweg bereithalten.
+- P4 aus dem aktuellen Branch mit `scripts/build_tab5.ps1` bauen und per
+ `scripts/flash_tab5.ps1 -Port COM_P4` installieren. Platzhalter ersetzen.
+- Den Build erst ausführen, wenn die vorhandenen lokalen Änderungen geprüft sind;
+ Release-Dateien und Test-Build getrennt halten. Keine Release-BIN als Fix-Build ausgeben.
+- Die Modulus-C6-App `modulus-tab5-c6-ota-app-v3.1.3-ota.bin` und das
+ Wiederherstellungsimage `modulus-tab5-c6-full-v3.1.3-ota.bin` aus dem Release laden.
+- Für einen reproduzierbaren Factory-Ausgangszustand das originale M5Stack-Full-Image
+ direkt auf den C6 schreiben. Ein Downgrade nur der App stellt die ursprüngliche
+ Partitionstabelle und OTA-Auswahl nicht zuverlässig wieder her.
+
+## Originaldatei und Anschluss
+
+- [Originales M5Stack-Image 1.4.1 herunterladen](https://raw.githubusercontent.com/m5stack/M5Tab5-UserDemo/main/platforms/tab5/wifi_c6_fw/ESP32C6-WiFi-SDIO-Interface-V1.4.1-96bea3a_0x0.bin).
+- SHA256 der geprüften Datei:
+ `1173bf86ab86c8dbd3f9863d10b15c2e46f57000b2b77c803e2b79bd0a3fa38e`.
+- Der C6 wird über den **internen Programmieranschluss mit USB-TTL-Downloader**
+ geflasht. M5Stack zeigt den passenden ESP32 Downloader und den Anschluss hier:
+ [Offizielle C6-Wiederherstellungsanleitung](https://docs.m5stack.com/en/guide/restore_factory/m5tab5_c6_wifi).
+- Die normale Tab5-USB-C-Buchse ist der P4-Zugang. Der dortige Downloadmodus
+ versetzt nicht einfach den C6 in den Programmiermodus.
+- Den COM-Port des Downloaders verwenden, unten beispielhaft `COM6`.
+- Optional zuerst den aktuellen 4-MB-C6-Flash sichern; das Backup kann Einstellungen
+ enthalten und bleibt lokal:
+
+```powershell
+python -m esptool --chip esp32c6 -p COM6 read-flash 0x0 0x400000 c6-before-legacy-test.bin
+```
+
+## 1. C6 auf Factory 1.4.1 setzen
+
+Im Ordner mit der Originaldatei, bei verbundenem C6-Downloader:
+
+```powershell
+python -m esptool --chip esp32c6 -p COM6 write-flash 0x0 ESP32C6-WiFi-SDIO-Interface-V1.4.1-96bea3a_0x0.bin
+```
+
+Verifikation abwarten, anschließend Tab5 vollständig neu starten. Das Full-Image
+überschreibt unter anderem NVS und OTA-Startdaten im abgedeckten Bereich.
+Es enthält die ursprüngliche OTA-Partitionierung. Kein zusätzliches `erase-flash`
+ist für diesen Ablauf vorgesehen.
+
+## 2. Alten Updateweg testen
+
+- Auf der **neuen Test-P4-Firmware** M Panel → C6 Update öffnen und Refresh drücken.
+- Die laufende Version muss **1.4.1** anzeigen. Der App-Descriptor der Originaldatei
+ enthält den Git-Stand `96bea3a`; das ist nicht die maßgebliche Laufzeit-Versionsabfrage.
+- Falls der C6 nicht antwortet: keine weiteren Flash-Versuche im Menü starten;
+ P4-Startlog sichern. Dann liegt bereits ein Verbindungs-/Versionsabfrageproblem vor,
+ das durch die Aktivierungsumschaltung allein nicht behoben ist.
+- `modulus-tab5-c6-ota-app-v3.1.3-ota.bin` ins Stammverzeichnis eines FAT32-Sticks
+ kopieren, an Tab5 USB-A anschließen, Refresh USB → Datei → Check image → Flash C6.
+- Erwarteter Logeintrag: `Running C6 1.4.1: legacy auto-restart OTA completion`.
+- Der C6 wird über OTAEnd aktiviert; ein zusätzlicher OTAActivate-Aufruf entfällt.
+ P4-Neustart nach acht Sekunden abwarten und Versorgung angeschlossen lassen.
+- Danach erneut die C6-Version abfragen: erwartet wird **2.11.4**, die Version
+ des ESP-Hosted-Anteils im Modulus-C6-Release. ESP-NOW-Verbindung prüfen.
+
+## 3. Neuen Updateweg gegenprüfen
+
+- Dieselbe Modulus-C6-App noch einmal über das Menü installieren.
+- Erwarteter Logeintrag: `Running C6 2.11.4: explicit activation OTA completion`.
+- Diesmal folgt auf OTAEnd die explizite Aktivierung; P4-Neustart nach drei Sekunden.
+- Erneut Version 2.11.4, Dashboard und Funkverbindung prüfen.
+
+## Wiederherstellung bei Problemen
+
+Mit dem internen C6-Downloader die Modulus-Full-BIN schreiben:
+
+```powershell
+python -m esptool --chip esp32c6 -p COM6 write-flash --flash-mode dio --flash-freq 80m --flash-size 4MB 0x0 modulus-tab5-c6-full-v3.1.3-ota.bin
+```
+
+Danach Tab5 neu starten. Full-BINs niemals im OTA-Menü auswählen.
+Für die Auswertung das P4-Startlog, erkannte Version, gewählten Modus,
+Fehlerphase und Version nach dem Neustart festhalten.

-# C6-Legacy-OTA mit Factory-Version 1.4.1 testen
-Dieser Test benötigt eine **neu gebaute P4-Firmware ab Commit 69ca844** auf
-`feature/tab5-ota`. Die vorhandenen Release-BINs v3.1.3-ota enthalten den Fix
-nicht, auch nach Ergänzung der Full-Images im ZIP. Die nachfolgenden Schritte
-beschreiben den Hardwaretest; er wurde noch nicht durchgeführt.
-
-## Vorbereitung
-
-- CNC stillsetzen. Verbindungsdaten notieren und einen Wiederherstellungsweg bereithalten.
-- P4 aus dem aktuellen Branch mit `scripts/build_tab5.ps1` bauen und per
- `scripts/flash_tab5.ps1 -Port COM_P4` installieren. Platzhalter ersetzen.
-- Den Build erst ausführen, wenn die vorhandenen lokalen Änderungen geprüft sind;
- Release-Dateien und Test-Build getrennt halten. Keine Release-BIN als Fix-Build ausgeben.
-- Die Modulus-C6-App `modulus-tab5-c6-ota-app-v3.1.3-ota.bin` und das
- Wiederherstellungsimage `modulus-tab5-c6-full-v3.1.3-ota.bin` aus dem Release laden.
-- Für einen reproduzierbaren Factory-Ausgangszustand das originale M5Stack-Full-Image
- direkt auf den C6 schreiben. Ein Downgrade nur der App stellt die ursprüngliche
- Partitionstabelle und OTA-Auswahl nicht zuverlässig wieder her.
-
-## Originaldatei und Anschluss
-
-- [Originales M5Stack-Image 1.4.1 herunterladen](https://raw.githubusercontent.com/m5stack/M5Tab5-UserDemo/main/platforms/tab5/wifi_c6_fw/ESP32C6-WiFi-SDIO-Interface-V1.4.1-96bea3a_0x0.bin).
-- SHA256 der geprüften Datei:
- `1173bf86ab86c8dbd3f9863d10b15c2e46f57000b2b77c803e2b79bd0a3fa38e`.
-- Der C6 wird über den **internen Programmieranschluss mit USB-TTL-Downloader**
- geflasht. M5Stack zeigt den passenden ESP32 Downloader und den Anschluss hier:
- [Offizielle C6-Wiederherstellungsanleitung](https://docs.m5stack.com/en/guide/restore_factory/m5tab5_c6_wifi).
-- Die normale Tab5-USB-C-Buchse ist der P4-Zugang. Der dortige Downloadmodus
- versetzt nicht einfach den C6 in den Programmiermodus.
-- Den COM-Port des Downloaders verwenden, unten beispielhaft `COM6`.
-- Optional zuerst den aktuellen 4-MB-C6-Flash sichern; das Backup kann Einstellungen
- enthalten und bleibt lokal:
-
-```powershell
-python -m esptool --chip esp32c6 -p COM6 read-flash 0x0 0x400000 c6-before-legacy-test.bin
-```
-
-## 1. C6 auf Factory 1.4.1 setzen
-
-Im Ordner mit der Originaldatei, bei verbundenem C6-Downloader:
-
-```powershell
-python -m esptool --chip esp32c6 -p COM6 write-flash 0x0 ESP32C6-WiFi-SDIO-Interface-V1.4.1-96bea3a_0x0.bin
-```
-
-Verifikation abwarten, anschließend Tab5 vollständig neu starten. Das Full-Image
-überschreibt unter anderem NVS und OTA-Startdaten im abgedeckten Bereich.
-Es enthält die ursprüngliche OTA-Partitionierung. Kein zusätzliches `erase-flash`
-ist für diesen Ablauf vorgesehen.
-
-## 2. Alten Updateweg testen
-
-- Auf der **neuen Test-P4-Firmware** M Panel → C6 Update öffnen und Refresh drücken.
-- Die laufende Version muss **1.4.1** anzeigen. Der App-Descriptor der Originaldatei
- enthält den Git-Stand `96bea3a`; das ist nicht die maßgebliche Laufzeit-Versionsabfrage.
-- Falls der C6 nicht antwortet: keine weiteren Flash-Versuche im Menü starten;
- P4-Startlog sichern. Dann liegt bereits ein Verbindungs-/Versionsabfrageproblem vor,
- das durch die Aktivierungsumschaltung allein nicht behoben ist.
-- `modulus-tab5-c6-ota-app-v3.1.3-ota.bin` ins Stammverzeichnis eines FAT32-Sticks
- kopieren, an Tab5 USB-A anschließen, Refresh USB → Datei → Check image → Flash C6.
-- Erwarteter Logeintrag: `Running C6 1.4.1: legacy auto-restart OTA completion`.
-- Der C6 wird über OTAEnd aktiviert; ein zusätzlicher OTAActivate-Aufruf entfällt.
- P4-Neustart nach acht Sekunden abwarten und Versorgung angeschlossen lassen.
-- Danach erneut die C6-Version abfragen: erwartet wird **2.11.4**, die Version
- des ESP-Hosted-Anteils im Modulus-C6-Release. ESP-NOW-Verbindung prüfen.
-
-## 3. Neuen Updateweg gegenprüfen
-
-- Dieselbe Modulus-C6-App noch einmal über das Menü installieren.
-- Erwarteter Logeintrag: `Running C6 2.11.4: explicit activation OTA completion`.
-- Diesmal folgt auf OTAEnd die explizite Aktivierung; P4-Neustart nach drei Sekunden.
-- Erneut Version 2.11.4, Dashboard und Funkverbindung prüfen.
-
-## Wiederherstellung bei Problemen
-
-Mit dem internen C6-Downloader die Modulus-Full-BIN schreiben:
-
-```powershell
-python -m esptool --chip esp32c6 -p COM6 write-flash --flash-mode dio --flash-freq 80m --flash-size 4MB 0x0 modulus-tab5-c6-full-v3.1.3-ota.bin
-```
-
-Danach Tab5 neu starten. Full-BINs niemals im OTA-Menü auswählen.
-Für die Auswertung das P4-Startlog, erkannte Version, gewählten Modus,
-Fehlerphase und Version nach dem Neustart festhalten.

-# Modulus Firmware – OTA für Tab5
-
-**Version:** 3.1.3-ota
-**Autor:** D. McLean / BufferRoot
-**Feature-Branch:** `feature/tab5-ota`
-**Plattform:** M5Stack Tab5 (ESP32-P4 + ESP32-C6)
-**Lizenz:** [MIT](LICENSE)
-
-Modulus ist eine CNC-Pendant-Firmware für das M5Stack Tab5. Der ESP32-P4 führt
-Oberfläche und Steuerungslogik aus; der ESP32-C6 stellt WLAN, BLE und ESP-NOW
-über ESP-Hosted/SDIO bereit. Das Pendant ersetzt nicht die Maschinensteuerung
-und nicht den hardwareseitigen Not-Aus.
-
-## Warum es diesen OTA-Feature-Branch gibt
-
-Modulus verteilt seine Aufgaben auf mehrere Prozessoren. Für Updates des
-ESP32-C6 im Tab5 und der ESP32-S3-Bridge war bisher jeweils ein separater
-USB-/Bootloader-Zugang nötig. Dieser Branch ergänzt **C6 Update** und
-**S3 Update** im M Panel. C6-App-Images werden intern über ESP-Hosted/SDIO
-übertragen, S3-App-Images per ESP-NOW. Beide Updater lesen ausschließlich das
-Stammverzeichnis eines FAT-formatierten USB-A-Sticks. Die microSD-Unterstützung
-war beim Entwickeln und Testen hilfreich, wurde aber aus den Updatemenüs
-entfernt: In vielen eingebauten Gehäusen ist der Kartenslot nicht erreichbar,
-und zwei mögliche Updatequellen machten den Ablauf unnötig uneindeutig. Andere
-microSD-Funktionen von Modulus bleiben unverändert.
-
-Der Ablauf lautet **zuerst P4, danach C6 und/oder S3**. Der XIAO ESP32-S3
-benötigt einmalig das OTA-fähige Vollimage per USB; alle späteren Updates nutzen
-nur das App-Image. Beide Seiten prüfen den ESP-Chiptyp und verlangen eine bewusste
-Freigabe. Nach erfolgreicher C6-Aktivierung startet der P4 nach drei Sekunden
-automatisch neu, um ESP-Hosted/SDIO wieder zu synchronisieren. Ein C6-Image kann nicht
-versehentlich über die S3-Seite geflasht werden und umgekehrt. Beide OTA-Wege
-wurden auf echter Hardware erfolgreich getestet.
-
-> [!IMPORTANT]
-> **OTA muss zuerst durch einen einmaligen kabelgebundenen Flash vorbereitet
-> werden.** Zuerst das P4-Paket per USB flashen, damit das Tab5 die OTA-Menüs
-> erhält. Ein neuer oder bereits anders geflashter XIAO ESP32-S3 muss danach
-> einmal per USB bei Offset `0x0` mit
-> `modulus-xiao-s3-first-flash-for-ota-*.bin` geflasht werden. Dadurch werden
-> OTA-Empfänger und Dual-Slot-Partitionstabelle installiert. Erst anschließend
-> funktionieren spätere S3-Updates mit `modulus-xiao-s3-ota-app-*.bin` über
-> **M Panel → S3 Update**. Das First-Flash-/Vollimage niemals im OTA-Menü wählen.
-
-Beim Tab5-C6 stellt die originale ESP-Hosted-Firmware Slave-OTA bereits bereit.
-Trotzdem muss zuerst die OTA-fähige P4-Firmware installiert sein, damit
-**C6 Update** verfügbar ist. Startet der C6 nicht mehr oder antwortet nicht über
-SDIO, muss zunächst das vollständige C6-Paket über dessen USB-Bootloader
-wiederhergestellt werden.
-
-## Architektur in Kurzform
-
-| Ziel | Aufgabe |
-|------|---------|
-| **ESP32-P4** | Tab5-Oberfläche, MPG und Steuerung; enthält C6- und S3-Updater |
-| **ESP32-C6** | WLAN, BLE und ESP-NOW über ESP-Hosted/SDIO |
-| **ESP32-S3** | ESP-NOW-Bridge im Schaltschrank zur CNC-UART |
-| **NanoH2** | Optionaler Zigbee-Koordinator |
-
-## Fertige Full-Images für v3.1.3-ota
-
-Die drei BINs direkt aus [Release v3.1.3-ota](https://github.com/fellpower/Modulus-Firmware/releases/tag/v3.1.3-ota)
-herunterladen. Ein lokaler Neubau oder Entpacken ist zum Flashen nicht nötig.
-
-| Ziel | Einzelne BIN | Flash-Adresse |
-|------|--------------|---------------|
-| Tab5 P4 | `modulus-tab5-p4-full-v3.1.3-ota.bin` | `0x0` |
-| Tab5 C6 | `modulus-tab5-c6-full-v3.1.3-ota.bin` | `0x0` |
-| XIAO ESP32-S3 | `modulus-xiao-s3-full-v3.1.3-ota.bin` | `0x0` |
-
-Die Images enthalten Bootloader, Partitionstabelle, gegebenenfalls OTA-Startdaten
-und Anwendung aus den vorhandenen Release-Einzeldateien. Der P4-Bootloader liegt
-innerhalb der BIN weiterhin bei `0x2000`, die XIAO-S3-App bei `0x20000`.
-**Die vollständige BIN wird trotzdem immer bei `0x0` geschrieben.**
-Lücken sind mit `0xFF` gefüllt. Das Schreiben kann Einstellungen/NVS und die
-OTA-Auswahl im beschriebenen Adressbereich zurücksetzen. Für spätere C6-/S3-Updates
-sind deshalb die App-only-Dateien vorgesehen.
-
-## Flashen per USB
-
-- Python und esptool installieren: `python -m pip install esptool==5.3.1`.
-- USB-Datenkabel verwenden, Terminal im Downloadordner öffnen.
-- COM-Port im Geräte-Manager prüfen; `COM5`, `COM6` und `COM8` sind Beispiele.
-- Den USB-Bootloader des richtigen Chips verbinden. Der P4-USB-Anschluss flasht
- den C6 nicht direkt. Der C6 benötigt den internen Programmieranschluss und einen
- USB-TTL-Downloader: [M5Stack-Anschlussanleitung](https://docs.m5stack.com/en/guide/restore_factory/m5tab5_c6_wifi).
- Bei Bedarf den jeweiligen Downloadmodus aktivieren.
-- Reihenfolge: P4 zuerst; C6 bei kabelgebundener Installation/Wiederherstellung;
- danach XIAO S3 einmalig für OTA vorbereiten.
-- Nur den Befehl für das gerade angeschlossene Ziel ausführen:
+# Modulus Firmware
-```powershell
-python -m esptool --chip esp32p4 -p COM5 write-flash --flash-mode dio --flash-freq 40m --flash-size 16MB 0x0 modulus-tab5-p4-full-v3.1.3-ota.bin
-python -m esptool --chip esp32c6 -p COM6 write-flash --flash-mode dio --flash-freq 80m --flash-size 4MB 0x0 modulus-tab5-c6-full-v3.1.3-ota.bin
-python -m esptool --chip esp32s3 -p COM8 write-flash --flash-mode dio --flash-freq 80m --flash-size 8MB 0x0 modulus-xiao-s3-full-v3.1.3-ota.bin
-```
+**Release:** v3.1.3-ota · **Branch:** `feature/tab5-ota` · **Lizenz:** [MIT](LICENSE)
+
+Modulus macht das M5Stack Tab5 zum CNC-Pendant. Der P4 übernimmt Oberfläche und
+Steuerungslogik, der C6 WLAN und ESP-NOW. Eine S3-Bridge verbindet das Pendant mit
+der CNC-Steuerung. NanoH2 ist der optionale Zigbee-Hub.
+
+## Erstinstallation
-Im grafischen Flashtool ebenfalls genau eine BIN bei `0x0` auswählen und
-Chip/Flash-Einstellungen passend setzen. Verifikation abwarten, dann neu starten.
-Ein zusätzliches `erase-flash` gehört nicht zu diesem Ablauf.
-Das bisherige `modulus-xiao-s3-first-flash-for-ota-v3.1.3-ota.bin` ist mit dem
-neuen XIAO-Full-Image inhaltsgleich. Nicht mit dem generischen S3-Bridge-Paket verwechseln.
-
-## C6-Kompatibilität in nachfolgenden Quellcode-Builds
-
-Der Branch fragt die **laufende C6-Version unmittelbar vor dem Schreiben** ab.
-Unter 2.6.0 werden 1024-Byte-Blöcke gesendet: Nutzdaten plus Protokollheader
-müssen in den 4096-Byte-Empfangspuffer von 1.4.1 passen. Neuere C6 behalten
-4096-Byte-Blöcke.
-Unter 2.6.0 (auch 1.4.1) aktiviert `OTAEnd` das Image und plant den C6-Neustart;
-ein zusätzliches `OTAActivate` entfällt. Der P4 wartet acht Sekunden bis zu seinem
-Neustart. Ab 2.6.0 wird explizit aktiviert, danach startet der P4 wie bisher nach
-drei Sekunden neu. Bei unbekannter oder nicht lesbarer Version wird nichts geschrieben.
-Eine funktionierende ESP-Hosted-Verbindung und geeignete C6-OTA-Partition bleiben
-nötig. Eine verlorene Abschluss-/Aktivierungsantwort wird als unbestätigter Zustand
-gemeldet, nicht als sicher ausgebliebene Aktivierung.
-
-**Diese Änderung gilt bisher nur für den Quellcode. Die Release-BINs v3.1.3-ota
-wurden nicht neu gebaut und behalten den bisherigen Ablauf.**
-Regressionstest: `python scripts/test_c6_ota.py` (benötigt Zig).
-Der Hardwaretest mit Factory-Firmware 1.4.1 steht noch aus.
-
-## Spätere Updates über USB-Stick und OTA
-
-- P4 normal starten und **M Panel → C6 Update / S3 Update** prüfen.
-- Passende Release-Datei herunterladen:
- `modulus-tab5-c6-ota-app-v3.1.3-ota.bin` oder
- `modulus-xiao-s3-ota-app-v3.1.3-ota.bin`.
-- Nur die App-BIN ins Stammverzeichnis eines FAT32-Sticks kopieren.
-- Stick in USB-A des Tab5 stecken; microSD wird im OTA-Menü nicht angeboten.
-- Passende Update-Seite öffnen, **Refresh USB**, Datei auswählen.
-- **Check image** beim C6 beziehungsweise **Check S3 image** beim S3 drücken.
-- **Flash C6** beziehungsweise **Flash S3** bestätigen. CNC im Leerlauf lassen;
- Stromversorgung und Stick während des Updates nicht entfernen.
-- Nach C6-Aktivierung startet der P4 nach drei Sekunden automatisch neu.
-- Nach erfolgreicher S3-Prüfung **Restart S3** drücken.
-- Dashboard und ESP-NOW-Verbindung prüfen. Falls Einstellungen zurückgesetzt
- wurden, S3-MAC und passenden Funkkanal unter **Settings → Wireless** neu setzen.
-
-**Full-Images gehören ausschließlich zum kabelgebundenen Flash bei `0x0`, niemals
-ins OTA-Menü.** Der XIAO braucht die vollständige USB-Erstinstallation einmalig.
-Startet der C6 nicht mehr oder antwortet nicht über SDIO, das C6-Full-Image über
-seinen USB-Bootloader wiederherstellen.
-
-## Full-Images ohne Neubau reproduzieren
-
-Aus dem Release `MANIFEST.json` sowie die ZIPs für `tab5-p4`, `tab5-c6` und
-`s3-xiao` herunterladen. Manifest in `dist/flash-images/v3.1.3-ota-source/` ablegen
-und die ZIPs darunter mit ihren Zielordnern und `flasher_args.json` entpacken.
+Die fertigen Dateien stehen im [Release v3.1.3-ota](https://github.com/fellpower/Modulus-Firmware-C6-OTA/releases/tag/v3.1.3-ota).
+
+- Das **Full-Image** enthält alles für die einmalige Erstinstallation und wird
+ bei Adresse `0x0` geschrieben. Full-Images gibt es für P4 und XIAO S3.
+- Das **App-Image** ist für spätere Aktualisierungen über die OTA-Menüs gedacht.
+- Für den **C6 gibt es genau eine Release-Datei**:
+ `modulus-tab5-c6-app-v3.1.3-ota.bin`. Sie wird immer über das C6-Menü des
+ Tab5 installiert, auch beim Wechsel von der Factory-Version 1.4.1.
+- Den C6 anschließend direkt über das Tab5 aktualisieren, wie unten beschrieben.
+
+Das aktuelle P4-Full-Image enthält den getesteten Kompatibilitätsweg für einen
+C6 mit der Factory-Version ESP-Hosted 1.4.1. Der Wechsel von 1.4.1 zur
+Modulus-C6-Firmware wurde auf dem Tab5 erfolgreich getestet.
+
+Das Ziel über seinen normalen USB-Anschluss verbinden und die passende einzelne
+Full-BIN an Adresse `0x0` schreiben. Beispiel für den XIAO (`COM8` durch seinen
+tatsächlichen Port ersetzen):
```powershell
-.\scripts\package_flash_images.ps1 -Version 3.1.3-ota
+python -m esptool --chip esp32s3 -p COM8 write-flash 0x0 modulus-xiao-s3-full-v3.1.3-ota.bin
```
-Das Skript prüft Größe und SHA256 jeder Eingabedatei gegen das Release-Manifest
-und übernimmt die Flash-Adressen aus `flasher_args.json`. Es führt ausschließlich
-vorhandene BINs zusammen. Ausgabe: drei Full-BINs, `SHA256SUMS-full.txt` und
-`FLASH-full.md` unter `dist/flash-images/v3.1.3-ota-full/`.
-Mit `-SourceRoot` und `-OutRoot` lassen sich andere Ordner angeben; bereits
-vorhandene Ausgabe-BINs werden nicht überschrieben. Die Images reichen bis zum
-Ende der enthaltenen Anwendung, nicht bis zum Ende des gesamten Flash-Speichers.
-[Prüfsummen der drei Full-Images](FULL-IMAGES-v3.1.3-ota.sha256).
-
-Das All-Firmware-ZIP enthält die drei Full-BINs direkt im Hauptordner sowie
-weiterhin alle bisherigen Einzeldateien, OTA-Apps und Lizenzen.
-`scripts/update_all_firmware_bundle.py` aktualisiert das Gesamtpaket einschließlich
-Manifest und Prüfsummen ohne Neubau; Aufruf in der englischen README.
-
-[Hardware-Testablauf mit C6-Version 1.4.1](C6-LEGACY-TEST.de.md).
-[Deutsche stichpunktartige Videoanleitung](VIDEOANLEITUNG.de.md).
-Weitere Architektur- und Build-Informationen stehen in der [englischen README](README.md).
-NanoH2 und generische S3-Bridge bleiben separate Release-Pakete mit eigener `FLASH.md`.
+NanoH2 und generische S3-Bridge haben eigene Pakete mit `FLASH.md`.
+
+## C6 über das Tab5 aktualisieren
+
+Für diesen Weg brauchst du einen FAT32-USB-Stick. Der C6 wird vollständig aus
+Modulus aktualisiert; dieses Release beschreibt keinen separaten C6-Flashweg.
+
+1. Tab5 mit aktuellem P4-Build starten.
+2. `modulus-tab5-c6-app-v3.1.3-ota.bin` ins **Hauptverzeichnis** des FAT32-Sticks kopieren.
+ Im Gesamt-ZIP liegt diese Datei im Ordner `ota/`.
+3. Stick in Tab5 USB-A stecken.
+4. **M Panel → C6 → Firmware Update** öffnen.
+5. **Refresh USB** drücken, Datei auswählen, **Check image** drücken.
+6. **Flash C6** drücken und bestätigen.
+7. Stromversorgung und Stick angeschlossen lassen, bis das Update und der automatische P4-Neustart beendet sind.
+8. C6-Version und ESP-NOW-Verbindung kontrollieren.
+
+Die P4-Firmware fragt die **laufende C6-Version** ab und wählt automatisch den
+passenden Ablauf. Bei alten Versionen wie 1.4.1 werden kleinere Blöcke verwendet;
+der P4 startet nach acht Sekunden neu. Ab ESP-Hosted 2.6.0 wird explizit aktiviert,
+danach startet der P4 nach drei Sekunden. Eine manuelle Moduswahl ist nicht nötig.
+
+Das gilt bei funktionierender ESP-Hosted-Verbindung und geeigneter OTA-Partition.
+Eine pauschale Garantie für jede fremde oder zukünftige C6-Firmware gibt es nicht.
+Bei nicht lesbarer Version beginnt kein Schreibvorgang.
+
+**Nur die C6-App-BIN gehört ins OTA-Menü.** Keine Full-BIN und kein ZIP
+auswählen. microSD ist keine OTA-Quelle.
+
+## Warum zwei Versionsnummern angezeigt werden
+
+| Anzeige | Bedeutung |
+|---------|-----------|
+| **Modulus release: v3.1.3-ota** | Installiertes Modulus-Release |
+| **ESP-Hosted (C6): 2.11.4** | Vom Funkprozessor gemeldete ESP-Hosted-Version |
+
+Die Datei `modulus-tab5-c6-app-v3.1.3-ota.bin` gehört zum Modulus-Release
+v3.1.3-ota und meldet trotzdem korrekt ESP-Hosted **2.11.4**.
+Der C6 meldet seine ESP-Hosted-Komponentenversion separat. Gleiche
+ESP-Hosted-Versionen beweisen nicht, dass zwei Firmwaredateien denselben Build enthalten.
+
+## Spätere S3-Updates
+
+`modulus-xiao-s3-app-v3.1.3-ota.bin` ins Hauptverzeichnis des Sticks kopieren.
+**M Panel → S3 → Firmware Update → Refresh USB → Check S3 image → Flash S3**.
+Nach erfolgreicher Prüfung **Restart S3** drücken. Bei Bedarf S3-MAC und
+passenden Funkkanal unter Settings → Wireless eintragen.
+
+## Aus dem Quellcode bauen
+
+ESP-IDF 6.0.1 und Zig 0.16 verwenden. P4 über `scripts/build_tab5.ps1` bauen;
+das Skript wendet die nötigen ESP-IDF-/ESP-Hosted-Patches an. Kein direktes
+`idf.py build` für den ersten P4-Build verwenden.
+
+C6: `scripts/build_tab5_c6_modulus.ps1`, anschließend `network_adapter.bin` über
+das Tab5-Menü installieren. Regressionstest: `python scripts/test_c6_ota.py`.
+Weitere Architektur- und Entwicklerdetails stehen in der [englischen README](README.md).
## Sicherheit
-Der Pendant-E-Stop an GPIO16 ist nur eine zusätzliche Softwarefunktion. Er ist
-kein sicherheitsgerichteter Abschaltkreis und kann bei ausgefallener
-Funkverbindung die Maschine nicht stoppen. Der echte Maschinen-Not-Aus bleibt
-immer die primäre Sicherheitseinrichtung.
+Updates nur bei stillstehender Maschine durchführen. Der echte Maschinen-Not-Aus
+bleibt die primäre Sicherheitseinrichtung; der Pendant-Not-Aus ersetzt ihn nicht.

+## Install and update
-Download the three full images from the existing
-[release v3.1.3-ota](https://github.com/fellpower/Modulus-Firmware/releases/tag/v3.1.3-ota).
-No local firmware build or ZIP extraction is needed to flash these BINs.
+Download the [v3.1.3-ota release](https://github.com/fellpower/Modulus-Firmware-C6-OTA/releases/tag/v3.1.3-ota).
+Use the P4 full image for the tablet and the XIAO full image for the S3 bridge.
+The current P4 full image contains the tested compatibility path for a C6 on
+factory ESP-Hosted 1.4.1.
-| Target | Single USB flash image | Address |
-|--------|------------------------|---------|
-| Tab5 P4 | `modulus-tab5-p4-full-v3.1.3-ota.bin` | `0x0` |
-| Tab5 C6 | `modulus-tab5-c6-full-v3.1.3-ota.bin` | `0x0` |
-| XIAO ESP32-S3 | `modulus-xiao-s3-full-v3.1.3-ota.bin` | `0x0` |
+### Full images and app images
-These combine the released bootloader, partition table, initial OTA data (C6/S3)
-and application. The P4 bootloader remains at `0x2000` inside its full image;
-the XIAO S3 application remains at `0x20000`. Always flash the **full BIN at `0x0`**.
-Unused gaps are filled with `0xFF`; writing a full image can reset NVS/settings
-and OTA selection within its address range. Use app-only OTA for later C6/S3 updates.
+- A **full image** contains everything required for the first wired installation.
+ Flash it once at address `0x0`. Full images are provided for P4 and XIAO S3.
+- An **app image** is used for subsequent updates from the Tab5 OTA menus.
+- The **C6 has one release file only**:
+ `modulus-tab5-c6-app-v3.1.3-ota.bin`. Install it through the Tab5 C6
+ update menu, including when upgrading from factory ESP-Hosted 1.4.1.
-### USB installation / recovery
+### P4 and XIAO initial installation
-Install esptool with `python -m pip install esptool==5.3.1`. Open a terminal in
-the download folder. Replace the example COM ports with the actual target ports.
-Use a USB data cable and connect the correct processor's USB bootloader: the
-Tab5 P4 port does not directly flash the C6. The C6 requires its internal
-programming connector and a USB-TTL downloader; see the
-[M5Stack C6 recovery guide](https://docs.m5stack.com/en/guide/restore_factory/m5tab5_c6_wifi).
-If necessary, enter the target's
-BOOT/download mode before connecting. Flash P4 first, then C6 if recovery or a
-wired installation is needed, then XIAO S3.
+Connect the target through its normal USB port and write the matching single
+full BIN at address `0x0`. This installs the complete bootloader, partition table,
+and application. Example for the XIAO:
```powershell
-python -m esptool --chip esp32p4 -p COM5 write-flash --flash-mode dio --flash-freq 40m --flash-size 16MB 0x0 modulus-tab5-p4-full-v3.1.3-ota.bin
-python -m esptool --chip esp32c6 -p COM6 write-flash --flash-mode dio --flash-freq 80m --flash-size 4MB 0x0 modulus-tab5-c6-full-v3.1.3-ota.bin
-python -m esptool --chip esp32s3 -p COM8 write-flash --flash-mode dio --flash-freq 80m --flash-size 8MB 0x0 modulus-xiao-s3-full-v3.1.3-ota.bin
+python -m esptool --chip esp32s3 -p COM8 write-flash 0x0 modulus-xiao-s3-full-v3.1.3-ota.bin
```
-Run only the command matching the connected chip. A GUI flasher likewise needs
-one file, address `0x0`, and the matching chip/settings. Wait for verification,
-then restart the board. A separate `erase-flash` is not part of this procedure.
-The older `modulus-xiao-s3-first-flash-for-ota-v3.1.3-ota.bin` is equivalent to
-the new XIAO full image. This XIAO image is not the generic S3 bridge package.
-
-### C6 compatibility in subsequent source builds
-
-The branch queries the **running C6 firmware immediately before writing**.
-Below 2.6.0, OTA uses 1024-byte blocks so the protobuf/TLV envelope fits the
-4096-byte receive buffer in 1.4.1. Modern slaves retain 4096-byte blocks.
-Below 2.6.0 (including 1.4.1), legacy `OTAEnd` activates the image and schedules
-the C6 reboot; no `OTAActivate` is sent. The P4 waits eight seconds before
-restarting. From 2.6.0 onward, explicit activation is followed by the existing
-three-second P4 restart delay. Unknown/unreadable versions stop before any write.
-A working ESP-Hosted connection and suitable C6 OTA partition remain necessary.
-A lost completion/activation response is reported as uncertain, not as proof
-that activation did not happen.
-
-**This change is source-only: existing v3.1.3-ota release BINs have not been
-rebuilt and retain the previous behavior.** Run the host regression test with
-`python scripts/test_c6_ota.py` (requires Zig). Hardware validation with factory
-1.4.1 is still required.
-
-### Later C6/S3 updates through Tab5
-
-1. Boot the P4 and confirm **M Panel → C6 Update / S3 Update** are available.
-2. Download `modulus-tab5-c6-ota-app-v3.1.3-ota.bin` or
- `modulus-xiao-s3-ota-app-v3.1.3-ota.bin` from the same release.
-3. Copy the matching **app-only** BIN to the root of a FAT32 USB drive and insert
- it into the Tab5 USB-A port. microSD is not an OTA source.
-4. Open the matching update page, press **Refresh USB**, select the file and
- **Check image** (C6) / **Check S3 image** (S3).
-5. Confirm **Flash C6** / **Flash S3**. Keep the machine idle and power/stick connected.
-6. C6 activation restarts the P4 automatically after three seconds. For S3,
- select **Restart S3** after successful verification.
-
-Never select a full BIN, bootloader, partition table, OTA-data file or ZIP in
-an OTA menu. The XIAO needs its USB full-image installation once before S3 OTA.
-If C6 cannot boot or answer over SDIO, use the C6 USB full image above.
-
-After flashing, check the dashboard and ESP-NOW connection. Set the S3 MAC and
-matching channel under **Settings → Wireless** again if settings were reset.
-NanoH2 and generic S3 packages remain available separately in the release;
-follow their included `FLASH.md`.
-
-### Reproduce the full images without rebuilding
-
-Download `MANIFEST.json` and the three release ZIPs
-`modulus-tab5-p4-v3.1.3-ota.zip`, `modulus-tab5-c6-v3.1.3-ota.zip`, and
-`modulus-s3-xiao-v3.1.3-ota.zip`. Place the manifest in
-`dist/flash-images/v3.1.3-ota-source/` and extract each ZIP below that directory,
-retaining its target folder and `flasher_args.json`.
+Replace COM8 with the XIAO port. NanoH2 and generic S3 bridge packages have their
+own `FLASH.md`; the XIAO image is specific to the XIAO board.
-```powershell
-.\scripts\package_flash_images.ps1 -Version 3.1.3-ota
-```
+### C6 update through the tablet
-The script validates input sizes and SHA256 against the release manifest and
-uses the recorded flash offsets. It only merges existing bytes with esptool;
-it never builds firmware or falls back to local build directories. It produces
-exactly the three full BINs, `SHA256SUMS-full.txt`, and `FLASH-full.md` under
-`dist/flash-images/v3.1.3-ota-full/`. Use `-SourceRoot` and `-OutRoot` to change
-folders; existing output BINs are rejected. These files are not padded to the
-entire flash-chip capacity. Compare hashes with the [recorded full-image checksums](FULL-IMAGES-v3.1.3-ota.sha256).
+The normal C6 update uses a FAT32 USB stick and the internal SDIO connection.
+The C6 is updated entirely from Modulus; no separate C6 installation procedure
+is part of this release.
-The all-firmware ZIP also contains the three full BINs directly in its root,
-plus the original per-target files, OTA apps and licenses. To update an existing
-bundle without rebuilding, download its ZIP, release `MANIFEST.json`,
-`FLASH-INSTRUCTIONS-EN-DE.md`, and `SHA256SUMS.txt` into a source folder, then run:
+1. Boot a current P4 build and open **M Panel → C6 → Firmware Update**.
+2. Copy `modulus-tab5-c6-app-v3.1.3-ota.bin` to the **root** of a FAT32 stick.
+ In the all-firmware ZIP it is in the `ota/` folder.
+3. Insert the stick into Tab5 USB-A, press **Refresh USB**, and select the file.
+4. Press **Check image**, then **Flash C6** and confirm.
+5. Keep power and the stick connected until the update and P4 restart complete.
+6. Check the running C6 version and ESP-NOW connection after reboot.
-```powershell
-python scripts/update_all_firmware_bundle.py --source dist/release-refresh/source --full-images dist/flash-images/v3.1.3-ota-full --output dist/release-refresh/upload
-```
+The P4 queries the running C6 version and chooses the transfer/completion method
+automatically. The 1.4.1 → Modulus v3.1.3-ota update has now passed on the user's
+Tab5. Older firmware uses smaller blocks and the P4 waits eight seconds; from
+ESP-Hosted 2.6.0 onward it uses explicit activation and waits three seconds.
+No manual mode selection is needed. This does not guarantee every third-party
+or future C6 image: the C6 must respond over ESP-Hosted and have a suitable OTA
+partition. An unreadable version stops the update before writing.
+
+**Only the C6 app BIN belongs in this menu.** Never select a full image or ZIP.
+microSD is not an OTA source.
+
+### Why two version numbers are shown
-Use an empty output folder. The helper checks the original bundle and full BINs,
-updates internal and external checksums/manifest, and writes a replacement ZIP.
-Upload all four output files together when updating the existing release.
+- **Modulus release: v3.1.3-ota** identifies the installed Modulus release.
+- **ESP-Hosted (C6): 2.11.4** is the radio firmware's reported component version.
+- `modulus-tab5-c6-app-v3.1.3-ota.bin` belongs to Modulus release v3.1.3-ota
+ and intentionally reports ESP-Hosted 2.11.4.
-German hardware test procedure: [C6 legacy OTA test](C6-LEGACY-TEST.de.md).
+The C6 separately reports its ESP-Hosted component version. An equal ESP-Hosted
+version does not prove that two BINs contain the same build.
-German recording notes: [Videoanleitung](VIDEOANLEITUNG.de.md).
+### Later XIAO S3 updates
+
+Copy `modulus-xiao-s3-app-v3.1.3-ota.bin` to the USB stick root. Open
+**M Panel → S3 → Firmware Update**, then **Refresh USB → Check S3 image → Flash S3**.
+After successful verification select **Restart S3**. Set matching S3 MAC/channel
+under Settings → Wireless if required.

-Merge the existing release files into full BINs: `.\scripts\package_flash_images.ps1` (see above).

-### Updating the Tab5 C6 from Modulus
-
-The Tab5 **M Panel → C6 Update** page updates the ESP32-C6 over the internal
-ESP-Hosted SDIO connection. Copy an ESP32-C6 **application image** (`.bin`) to
-the root of a FAT32-formatted USB drive, insert it into USB-A, and open the page. For builds
-from this repository, that application is
-`firmware/tab5-c6/build/network_adapter.bin`. Use
-**Refresh USB**, select the file, then **Check image**. Modulus verifies the ESP
-image header and ESP32-C6 chip ID before enabling **Flash C6**.
-
-Flashing never starts automatically. Keep power and the USB drive connected while
-the progress bar is active. After successful activation, the P4 automatically
-restarts after three seconds so it can reconnect to the updated C6 firmware.
-
-Use an ESP-Hosted slave application image compatible with the host component
-version pinned in `firmware/tab5/dependencies.lock`. Do not use a full-flash,
-merged, bootloader, or partition-table image.
-
-Recovery: if the C6 update is interrupted and SDIO no longer starts, restore a
-C6 full image through the C6 USB bootloader at `0x0` (see above). The P4 OTA page cannot repair a C6 that no longer boots far
-enough to provide ESP-Hosted OTA.
+Host regression test for C6 OTA: `python scripts/test_c6_ota.py` (requires Zig).
