Rollback to Arduino / ESP-IDF on ESP32-S3 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 UART port
  2. Check the port address with ls /dev/cu.* 
     $ ls /dev/cu.*
 /dev/cu.Bluetooth-Incoming-Port  /dev/cu.SLAB_USBtoUART  /dev/cu.usbserial-1410
  3. Erase the flash 
     $ esptool.py --port /dev/cu.usbserial-1410 erase_flash

 esptool.py v4.3
 Serial port /dev/cu.SLAB_USBtoUART
