I have trouble programming my ESP32-C3 2MByte board with the Arduino framework. (It’s working with the Arduino IDE).
I found hints in other topics for the .ini file, for the .csv file etc, unfortunately all of my efforts failed. Compiling and upload is succesful, but the firmware is not working.
Could you please upload a working blink or other simple working example for the 2MByte ESP-C3-32S board? Schematics is the same, as the Espressif M1 board, just the flash is smaller.
The flash connection mode (Quad-I/O). Something is not working correctly with that in general, or your board is connected via DIO (Dual-I/O) to the flash chip.
I had to remove the RTS and DTR connections, and use the buttons, because the serial monitor is not working with that connections (the terminal resets the uC).
