Gemma bootloader unrecoverable

Post by dielemma »

I recently purchased two Adafruit Gemma boards.
I uploaded a sketch to both of them that was a bit too big, and it corrupted the bootloader. I followed the instructions here:
"https://learn.adafruit.com/introducing- ... bootloader"
to repair the bootloader, but it only worked for one of the Gemma boards. The other board gives the error:
"Verifying fuses...
Low Fuse: 0xF1 is 0xFE
Failed to verify fuses"

I'm stuck.

Check your wiring - sounds like you have a loose connection.
