Gemma M0 is recognized but doesn't go into bootloader mode

Post by eamarti »

I got the Gemma M0 about a week ago and have been unable to use it. I got the correct data cable and my system picked it up however I was unable to write to it. The Gemma just cycled through a rainbow of colors but would not stay on green like the videos showed. I have solved my issue and wanted to post just incase anyone had the same thing.

solution: In the PDF instructions it specifies to press the reset button twice consecutively. This allowed the light to stay on green, then I was able to enter bootloader mode from there. The online instructions are missing that part.
