#26 Cariboulite on Pi 5

[Tom S]

Any chance at getting the cariboulite working on a Raspberry Pi 5 I am getting gpio errors

Is there a known workaround for the pi 5 and gpio yet on 22.04? I know I can install Ubuntu 23.10 and the caribou should be working but I like DragonOS.

Tom,

Have you tried on 23.10? If it’s working, I’d like to dig into what’s different about 23.10.

Fresh install of Ubuntu 23.10 is not working I get the same gpiomem error. I have not tried the official raspberry pi os yet.

So it looks like they changed the GPIO access on the pi5's as it goes through the pcie now apparently. This is our problem.
