GEMMA M0 won't load

Post by batesterman »

Please excuse my newness,
GEMMA M0 won't load with IDE.
Tried to load strand test for Dotstar LED built in. This is when it stopped. (#include <Adafruit_DotStar.h>, #define DATAPIN 7, #define CLOCKPIN 8, etc...)
Have been using this board for weeks, no issues. When I plug in a different GEMMA M0 it works, no issues. I am confident the issue is with this GEMMA M0.
Now when GEMMA is plugged in, the IDE port does not list the GEMMA.
When I double tap reset on GEMMA, the led goes green, the IDE port is there" Port: "/dev/cu.usmodem14101 (Aadafruit GEMMA M0)
Try to load simple blink program for testing https://learn.adafruit.com/experimenter ... 01-code%20
I check it (again), and press "Load" from IDE. No device found on cu.usbmodem14101\\
I try this in the second GEMMA M0, and it works no issues.
What is the next step to try?

Okay, I followed the instructions here: https://learn.adafruit.com/welcome-to-c ... cuitpython
Must have had a corrupted file.
This required the use of a Win10 computer to do this.
On a mac, the boot disk on the GEMMA M0 would not show up. So I couldn't use the .uf2 file.
Followed the instructions and all is back and running.

@batesterman,

I plugged in a GEMMA M0 into my Mac (10.14.6) just now. It correctly showed up as CIRCUITPY and with a double reset button press it showed up as GEMMABOOT. You should see the same on yours now.
