I've been trying to program my ESP32-C3 board, but so far Arduino IDE worked for me, but this is not the solution I want to go with. I've installed ESP-IDF via platformio on my Mac, (removed EC-ACC certificate in order to compile successfully) and tried to upload blink example sketch from ESP-IDF.
It connected to my board and apparently started to uploading, but when it finished the ESP did nothing. No (desired) serial output nor any "blinking" pin.
I'm using a custom devboard made by Bastlir, schematic can be found here: https://github.com/Bastlirovo/esp32c3-m ... main/HW/v1
As this board is meant to be programmed via internal USB, I had to enable "USB CDC on boot" setting in Arduino and upload mode set to "internal USB". I've found similar settings for platformio, but I'm not really sure if they are the correct ones;
My Platformio.ini file:
