Hallo,
i finally got my new board ESP32S-DEVKITC-1-N8R2 to work.
I tried an example with RGB-LED there was no problem.
When i try to flash the code for wlan on the chip using micropython i got the foloowing error:
Unable to connect to COM7: Cannot configure port, something went wrong. Original message: PermissionError(13, 'A device attached to the system is not functioning.', None, 31)

If you have serial connection to the device from another program, then disconnect it there first.

Process ended with exit code 1.

Has someone faced this problem and figured out a solution?
I appreciate any help

Thanks a lot in forward
