Failed on Rpi2 and AlpineLinux #590

Closed blahlt closed 11 months ago

blahlt commented 11 months ago

Failed to run on Raspberry Pi 2 Model B V1.1 (OS: Alpine Linux (alpine-rpi-3.18.4-armv7))

I always get an error message: initPeripherals: mmap gpio failed (Invalid argument) Can't initialise pigpio library

Are there any solutions?

I think the memory mapping requires assistance from the VPU firmware (mailbox registers). I’m not aware of how to enable non RasperryPi OS to do this.

Yeah, it works on Raspberry Pi OS, but not on Alpine Linux :(
