LinuxCNC on Raspberry Pi 5

Category: Installing LinuxCNC

Already built the Trixie image, just wanted to make sure there were no gotchas. Haven't added desktop yet, I'll do that when the base image boots from nvme drive on the Pi. Build the packages, put them up on github like before and build a full image.
Eventually this will need building once Trixie is officially released, might as well start checking if anything goes pear shaped.

I started with the most recent pull from pyavitz's repo and hoping that it's just the user script is needed to be slotted in and of course the userdata.txt I used for the Bookworm build. Oh and turn SPI on as default and just for myself as I'm probably the only one that uses midnight commander ditch the red & green defaults.

With regards to network manager, I really haven't noticed an issue with it on the RPi5 even with gnome network manager, reckon it's worth putting it in ? Another personal pref as it's easy to turn wifi on & off when needed.
Does this affect ethercat ?

LinuxCNC on Raspberry Pi 5

Category: Installing LinuxCNC

Hello everyone,

I started to work with linuxcnc only a few weeks ago, when I decided to upgrade my 3d printer with A and B axis.
Because my pi4 was starting to jitter I acquired a pi5. :) As one does.. :)

I etched the image 2.94 for pi5 to an SD card. Running this image, GPIO is not working.

halcmd loadrt hal_gpio help
Note: Using POSIX realtime
Invalid parameter `help'
<commandline>:0: waitpid failed /usr/bin/rtapi_app hal_gpio
<commandline>:0: /usr/bin/rtapi_app exited without becoming ready
<commandline>:0: insmod for hal_gpio failed, returned -1
cnc@raspberrypi:~$

I dont have the knowledge to troubleshoot this. Unfortunately. Maybe somebody here know how to solve this.

kind regards,
JAiro

You could also try installing Debian Trixie from the debian image now its available
raspi.debian.net/daily-images/

Note that this will not install a desktop, just a console but it will have a preempt_rt kernel available. I did do up a doc on doing this for Debian Bullseye which will basically be the same.

docs.google.com/document/d/1S0K-UBlXnsYC...b_0/edit?usp=sharing

The name for xfce package might have changed search the debian packages for XFCE to get the right name today.

Once again thanks mate.

I'm going to play around with making an RPi5 image based on Trixie\Testing so I'll give it a whirl.

You might as well use the provided image becasue you basically end up with Trixie (with 6.1.2 kernel) and 2.9.4 already installed.
