Errno 19 when following guide: Mirco:Bit V2

Hi Core Electronics Team,

I work in Inclusion Support at a school and have a student attempting to use the Micro:Bit V2 and the Piicodev starter kit. When following the guides for any of the modules, the microbit returns “OSError: [Errno 19] ENODEV”.

I have attempted to Google this but have come up empty. I have had this occur with the RBG, Buzzer, and Atmopsheric Sensor Modules. However, they all receive power and I have tried different cables.

Does anyone know how to fix this?



Hi Daniel,

Cursory reading reveals this may mean your micro:bit is running out of flash room, or maybe it’s a bad connection:

Are you able to share a photo of your wiring, and the code you’re running? That’ll allow us to check both for you and get closer to the solution on this one :slight_smile:
