Micropython on ESP32-C3

Hello
I have received my ESP32-C3 engineering samples (ESP32-C3-DevKitM-1) and wanted to know if I can program them in Micropython using the firmware available for ESP32.
Thanks!

Given that it's based on RISC-V it will need a new specific MicroPython port. There is work going on to port the S3, but that uses the Xtensa arch.

May I ask a question,when dose the micropython firmware for c3 can be published? thank you.

The build for ESP32-C3 is under construction. See
https://github.com/micropython/micropython/pull/7438
From that PR it is possible to build a trial version.

I've just pushed a container to the docker hub that can help build that. You should be able to use:
Code: Select all
> docker run -ti --rm -v ~/my_micropython:/micropython micropython/build-micropython-esp32 bash -c -l "cd micropython && make -C mpy-cross && make -C ports/esp32 submodules && make -C ports/esp32 BOARD=GENERIC_C3"
Assuming you have a clone of MicroPython (checked out to the ESP32-C3 #7438 PR) on your host at ~/my_micropython.
