I can confirm that the image in this link works with a Raspberry Pi 4 with 4Gb but does not work with an Rpi400.


Great, I was able to install it too but I did not get the PREEMPT_RT kernel on my Pi 4B and had some stability issues
Just this minute, I have finished compiling linuxcnc from source after installing the PREEMPT_RT based on this method
github.com/kdoren/linux/releases/tag/rpi_5.15.27-rt35
and this 64 bit image
downloads.raspberrypi.org/raspios_arm64/...os_arm64-2022-04-07/
I have a long way to go to understand the pi

So I assume that the install:apt install linuxcnc-uspace linuxcnc-uspace-dev mesaflash

Was built against the stock non-RT kernel installed with Bookworm?

Lcnc is not built against preempt_rt but requires it to do real time stuff. I can't really remember what i did but th epreempt_rt kenrel on the pi required a "special" install

Got you, Thanks.

This install is just for Debian 12 on a regular type PC.

Now in the Debian repos for Bookworm: linuxcnc-uspace (2.9.0)

packages.debian.org/bookworm/linuxcnc-uspace

And the preempt_rt patch is a dependency of lunuxcnc-uspace so it should get installed with linuxcnc. so a simple reboot should be all that is required.
