Xiao ESP32-C6 in CircuitPython

EDIT: as of today (08/22/2024) there is official support from Adafruit for Xiao ESP32-C6 CircuitPython: https://circuitpython.org/board/seeed_xiao_esp32c6/ .

I made it work, flashed the CircuitPython firmware to the ESP32-C6. Turns out you have to use the "Flash download tool" from Espressif https://www.esp32.com/viewtopic.php?t=60&start=20 . I downloaded the bin file for the "ESP32-C6-DevKitC-1-N8" from here https://circuitpython.org/board/espressif_esp32c6_devkitc_1_n8/ , which I do not know to be exactly compatible with the Xiao ESP32-C6, have not tested it fully.

Tools like the "Web serial ESPtool" did not work for me https://learn.adafruit.com/circuitpython-with-esp32-quick-start/web-serial-esptool

Tested my flashing with the LED blink in Thonny IDE:

import time

led = digitalio.DigitalInOut(board.IO18)
led.direction = digitalio.Direction.OUTPUT

while True:
    print(microcontroller.cpu.temperature)
    print("On!")
    led.value = True
    time.sleep(0.5)
  
    print("Off!")
    led.value = False
    time.sleep(0.5)
