TTGO Lora32 V2.1 PlatformIO does not recognize upload port

[DL4ZAQ]

Describe the bug

TTGO Lora32 V2.1 Does not boot image after upload via Upload File System image in PlatformIO. Build ok in PlatformIO Upload ok in PlatformIO Board stays with the meshtastic firmware on it after it rebooted. Tried it many times with always the same result.

• OS: Win 10
• PlatformIO Version: Newest
• Firmware Version: Newest

BTW I changed the board and tried also V2.1, V1.0 as well as T-Beam (yes I am really lost at this point) without success. To me it seems that there is no data flashed to the Device… no matter what the terminal is telling me. At least it appears, that the currently installed meshtastic software is still there. I also tried to do a flash erase - then the screen of the TTOG Device is black but it does not change it´s behavior after uploading the file system. I have no clue.

I found this meanwhile this but it does not help me at all - did the procedure but without success:

What can I do? Any hints? Can this be fixed in the software?

Hi Peter!

To flash the board, you need to execute 2 steps (one time to upload the firmware, the second time is to upload the configuration).

You can find more here: https://www.lora-aprs.info/docs/LoRa_APRS_iGate/quick-start-guide/ or on some youtube videos (Manuel Lausmann, etc)

Hallo Peter, vielen Dank für Deine Hinweise.

Zwischenzeitlich kompiliert die Software - schön. Aber leider komme ich trotzdem nicht weiter.

Leider kann ich die Software nicht auf das Board übertragen. PlatformIO erkennt den Upload Port nicht und der Vorgang wird abgebrochen. Im Win Dev. Manager ist das Board erkannt. Den COM Port habe ich dann auch in der PlatformIO.ini als Upload port "fest" verdrahtet... ohne Erfolg. Darauf hin habe ich alles mögliche versucht um den "Fehler" zu finden. Aber das liegt wohl an meiner Installation, die ich übrigens mehrfach deinstalliert und neu aufgesetzt habe. Auch das hat alles nichts gebracht.

Unter Linux habe ich das ganze dann auch noch mal aufgesetzt aber da kompiliert der Code schon gar nicht... Ich bekomme immer Fehlermeldungen und kaum habe ich eine Hürde genommen, kommt die nächste.

Das frustriert... Ich habe das Board jetzt als GS-Groundstation geflashed - hat auf Anhieb funktioniert. Als Meshtastic Node: auf Anhieb funktioniert.

Mit Verlaub: Der LoraTracker war innerhalb von wenigen Minuten auf meinem T-Beam lauffähig.

Irgendwie habe ich jetzt nach vielen Stunden die Lust verloren.... und gebe auf. Warum muss das alles so kompliziert sein?

Danke und Gruss Peter
