Can't enter bootloader mode on GEMMA v2
When I power the GEMMA by USB (I've tried 5 different cables now), there's just a pulsating rainbow of colors on the onboard rgb. Pressing the reset button causes the red button to flash quickly for a fraction of a second and then back to the rainbow flashing.

Re: Can't enter bootloader mode on GEMMA v2
The rainbow flashing is most likely a CircuitPython error code. What is output in the REPL?
If you aren't familiar with using the REPL (or even just the serial connection), see

Double-pressing reset should put you in bootloader mode and mount the GEMMABOOT drive.

Double clicking the reset did the trick, thank you.
