Description
I am trying to build micropython and flash it to an ESP32C3 board while it seems that there is
no output/REPL on the serial port. I have successfully verified my env by:
1. Run the 'hello_world' demo in espressif via 'idf.py build flash'.
2. Flash the official mp image 'esp32c3-20230426-v1.20.0.bin' and run some demos via mpremote.
My env:
- Ubuntu 22.04
- idf: v5.1
- Micropython:
