esptool -esp chip option wrong

[alka79]

Arduino IDE 2.3.2 , windows 10 , MH-ET-LIVE ESP32MINIKit board.

esptool complains about --chip option

When I run the above command from a shell with --chip esp32 the upload works fine.

What is your exact FQBN? It looks like you are not using the official ESP32 core, which has "esp32" as the architecture (2nd section of the FQBN).

My board is branded by AZ Deliverly. It is a clone of Wemos MINI D1 ESP32 also known as MH ET LIVE MINIKIT ESP32. Hard to know which one is the original manufacturer !

I tried with both boards names available in the boards list:

• d1_mini32
• mhetesp32minikit

littlefs upload fails with both for the same reason : --chip option incorrect. It seems that --chip option passed to esptool_py is the board ref instead of the target architecture.

I use latest boards ESP32 2.0.15

this is the description in board.txt of one of the boards ##############################################################

Looks like the ESP32 doesn't really use the FQBN architecture since there's only 1 core but something like 6 variants. Please try #26 and report back, it uses the build.mcu setting which seems to match their platform.txt build recipes.

1.1.5 works fine for me on ESP32. Thanks a lot for your work.
