I think I corrupted my Metro Grand Central. How to resolve?

Post by owntheweb »

Hello,
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).
Wasn't there an Arduino sketch tool that could be used to recover on Windows? Any other ideas? Thanks a ton in advance! :)

I'm good to go. Found the helpful troubleshooting page:

https://learn.adafruit.com/welcome-to-c ... 3105309-32

Something was rather funky. First I loaded a sketch, which worked (cool!)

I then found the troubleshooting guide I made it all the way to the erase option (skipping REPL). Not sure if the erase worked as I still saw the file and it didn't restart. However after that I retraced my steps, updated the bootloader, installed the latest CircuitPython, then good to go.
