Rollback to Arduino / ESP-IDF on ESP32-S3

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
    Connecting....

4. Plug into the USB port of the board
5. Flash in the blinky example via ESP-IDF
6. Disconnect any serial monitor running the logs (if any).
7. Flash in the blinky example for Arduino
