I have seemingly got my Circuit Playground Express stuck in Bootloader mode (pixels constantly green) and it won't upload new code via the IDE.
I think this happened because I was reflashing a different board and left the Programmer set on "Arduino as ISP" when uploading code to the Playground, now its back on "AVRISP Mk II" but the board won't accept new code.
I have tried to update the bootloader as a solution but this hasn't taken it out of the green light mode.
Anyone know how to fix this?

Re: Stuck in Bootloader Mode
Are you seeing the CPLAYBOOT folder?

Yes that is what I see, all the information I can find says that you will get this folder when pressing the reset button but for me it is always on. The reset button does not turn it off.adafruit_support_carter wrote:Are you seeing the CPLAYBOOT folder?

Re: Stuck in Bootloader Mode
Try downloading the precompiled example here:
https://learn.adafruit.com/adafruit-cir ... /downloads
At the bottom of that page there's a green button that says "Original Arduino Demo shipped with Circuit Playground Express". Click on that to download the UF2 file. You do not need Arduino installed. Drag the downloaded UF2 file to the CPLAYBOOT folder. See if it will then run the demo.

It will run the demo but still will not upload new code via the Arduino IDE, I am only trying an example circuit playground code.adafruit_support_carter wrote:Try downloading the precompiled example here:

Re: Stuck in Bootloader Mode
Please turn on verbose output in Arduino and paste the error messages seen in the Arduino IDE when trying to upload a sketch.
