This is typically the consequence of one of:

  • a bad USB cable
  • bad serial port driver
  • too high of a baud rate (although that's usually linked to other reasons, like running in a virtual machine...)

Do you know whether your hardware setup "should" be working? That is, have you maybe used your machine with another environment (like esp-idf, Arduino...) before?

After getting Thonny with micropython working with my ESP32's I tried again and now flashing works. Scan does not but scan ip-address finds the device and I can run a small program. I will close this issue and. In order to keep the issue list clean, I will address further questions to Discord

Do you maybe have an idea of what changed that could be the reason?
Was there anything non-Thonny related (like installing a fresh driver) that could have fixed the issue?
