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.

So, some months on (and hopefully after quite a bit more testing) is this now the best way to install LinuxCNC on a normal PC?

Do you just install the current stable debian (bookworm) and then apt install linuxcnc-uspace?

the 2.9 docs are now your friend

This thread is now obsolete

Actually, Tommy, perhaps you could edit the first post pointing them to that link and advising of the new method 
The links are wrong now that Bookworm has been officially released.

I went through the forum and edited a lot of my posts to reflect this.
