My Google searches aren't hitting the mark today. I have a Metro Grand Central M4 operating as a MIDI device, running CircuitPython. I accidentally left it plugged into my Windows PC on shutdown/restart. Now the drive won't mount and the code is not running. I just have one green light on for power I think.
However there's hope:
- The device is recognized as a device in Windows (just not showing as a drive)
- I can double push the reset button and get the METROM4BOOT drive will show.
- I can load a new bootloader (although that doesn't resolve issue).
