LinuxCNC on Raspberry Pi 5

Mines on its way now......to Asutpost being Austpost it may get here just before the sun goes out.

Hi, 

that is what I tried to point out in my previous message:  forum.linuxcnc.org/9-installing-linuxcnc...pi-5?start=10#285154

Setting the board to BCM2712 does not work and the RPI5 gets into a "running /scripts/local/block" loop

As an additional note, there's this also written in the PREENPT_RT release page ( github.com/kdoren/linux/releases/tag/rpi_6.1.54-rt15 )

NOTE: The installation instructions in the wiki work for debian bullseye, and currently require changes for debian bookworm. Bookworm (like Ubuntu) expects the files to be copied into directory 

Code:

/boot/firmware/

 instead of 

Code:

/boot/

For those who want to use the Raspberry Pi 5 with RaspiOS 64bit containing PREEMPT_RT, an image is available at this link: drive.google.com/file/d/16kKamxMKPdYAeJp...KLf/view?usp=sharing

On this image you can easily install a version of LinuxCNC with the installer script
www.linuxcnc.org/linuxcnc-install.sh
or by downloading the latest version 2.9.1 .deb packages from here
ftp.debian.org/debian/pool/main/l/linuxcnc/?C=M;O=D
Unfortunately, packages for bookworm and arm64 are not available at buildbot.linuxcnc.org/ .

Finally you can create the latest version of LinuxCNC as reported here:
linuxcnc.org/docs/devel/html/code/building-linuxcnc.html

I reported on another thread.
Yesterday, I built a Pi5 version of the Official Linuxcnc image and shared it here
drive.google.com/file/d/1H_q0Ra-27ZDOhqu...x1f/view?usp=sharing
Upstream have included support for the pi5 but its untested due to lack hardware
Please give it a go and report back.
user = cnc 
password = cnc
run sudo menu-config to congigure wifi, locales, and user credentials
This time I added network-manager which should allow networks to be configured from the desktop

My concern here is I had to use the Raspberry 6.61 kernel to get Pi5 support but the latest RT patch is only for 6.54 so this could introduce bugs.

 

The patches haven't been causing any issues yet. My Pi has been on for hours at a time, compileda few kernels and did a 6 minute RIP build of Linuxcnc.
Once I sort the driver out I can run a few Configs. Sims seem to be ok.

Once I've sorted my issues out I'll test your image Rod. I'm not ignoring your efforts just need to sort things out at my end.

I have a Mesa 7C80, I will test SPI. Are there certain test-commands?
My Pi5 will arrive soon. I hope the 7C80 will give enough power for it. Only 2.5A according to the manual, and there is an SSD connected to it.

And then there are the Elo Touch drivers, hope they work too....

I didn't make life easy by buying a 7C80............... but it looks cool
