Support for eth01-evo board / chip ESP32-C3

[Tobi4]

Is there any possiblity to flash the eth01-evo board, chip ESP32-C3 with the solution?

I'm running into the issue that the flash process aborts with the error message

A fatal error occurred: This chip is ESP32-C3 not ESP32. Wrong --chip argument?
CMake Error at run_serial_tool.cmake:56 (message):
  /opt/esp-idf-tools/python_env/idf4.4_py3.9_env/bin/python
  /opt/esp-idf/components/esptool_py/esptool/esptool.py --chip esp32 failed

I also tried to create a new build running the command upfront idf.py set-target esp32c3, but this does not change the target chip when trying to flash.

Any help would be useful. Thanks in advance.

Unfortunately this project only supports the ESP8266 and ESP32 (base) targets.

The esp-idf target is set in the sdk/esp-idf/Dockerfile Docker image, and it should be possible to change the ESP_IDF_TARGETS and build an SDK image for the esp32c3 target.

However, a lot of the lower-level components, and i2s_out in particular, use the i2s_ll.h or i2s_struct.h interfaces, which are target-specific, and the implementation would need to be explicitly ported to the esp32c3 SOC.

This is probably possible, but the ESP32 (base) SoC is the only one that has an actual Ethernet MAC with a RMII interface. I'm personally a little skeptical of the SPI-based Ethernet MAC/PHYs used in boards like the https://github.com/AI6YP/eth01-evo, but I can be convinced otherwise - but I'm doubtful if I would ever make the effort to port it by myself.
