Tufty2040 - device is busy or does not respond

Hello, complete beginner to the 2040. Getting this error message in Thonny.

Device is busy or does not respond. Your options:

  • wait until it completes current work;
  • use Ctrl+C to interrupt current work;
  • reset the device and try again;
  • check connection properties;
  • make sure the device has suitable MicroPython / CircuitPython / firmware;
  • make sure the device is not in bootloader mode.

Followed Hel Gibbons getting started tutorial. It worked once, never worked again. Have tried Control+C, and tried stopping and starting, turning off and on again etc.

Have not tried reinstalling software.

Thanks!

Scroll down to the Resetting Flash Memory part and there is a flash_nuke.uf2 file that will erase everything and let you start over fresh.

Put it in boot mode, then drag and drop it to your Tufty in file explorer. Then do the same for the Tufty uf2 file.
