LinuxCNC on Raspberry Pi 5

I can spend some time on this. Can we start a DM conversation? I've built Linux deployments before.

The driver will need a rewrite, more than likely, due to the I\O being moved to the RP1 chip. So if you want to get into some driver coding go for it.

Hi Cornholio, Stupid question- Lack of I/O support wont affect the 5's ability to run an ethernet card? (I have one on the way, still trying to decide what machine i want to use to drive it) Just my luck that there would be some weird conflict that means its a no-go.

Should be ok.
Haven’t tested it myself.

It would be great if you could point me to some appropriate build instructions. I can look at the driver.  I'm plenty familiar with building Linux, but I'd love to have a pointer to the exactly correct repos.  I haven't easily found this on this forum yet.

You'll have to dive into the RP1 as the IO has been moved off the BCM2712, the RPi4 had the IO on the BCM2711.

I had a bit of play but decided to move to another setup.
