<![CDATA[Unit CamS3 and MicroPython]]>Hi,

I wish to program Unit CamS3 using MicroPython but when I flash them using this:

I ge this shell message in Thonny even before I start to program:
PROBLEM IN THONNY'S BACK-END: Internal error (serial.serialutil.SerialTimeoutException: Write timeout).
See Thonny's backend.log for more info.
You may need to press "Stop/Restart" or hard-reset your MicroPython device and try again.

Process ended with exit code 0.

As "Stop/Restart" cycles does not solve, any idea how to solve it? and to start programming?

This is not a Micropython firmware. You might need to configure and flash the firmware yourself: https://micropython.org/download/
