Rollback to Arduino / ESP-IDF on ESP32-C3 prototype

Description

Use the rollback feature if the dev board has been flashed with Micropython or Tasmota and you need to use it with ESP-IDF / Arduino again.

Rollback steps

  1. Plug in the board on the USB port
  2. Check the port address with ls /dev/cu.* 
     ls /dev/cu.*
  3. Erase the flash 
     esptool.py --chip esp32c3 --port /dev/cu.SLAB_USBtoUART erase_flash
  4. Flash in the blinky example via ESP-IDF
  5. Disconnect any serial monitor running the logs (if any).
  6. Flash in the blinky example for Arduino
