LinuxCNC on Raspberry Pi 5

If it's Rod's image can you change the resolution and does it identify the display\monitor? From what I've seen it's stuck at a single resolution and it can't identify the dsiaplay as the RPi4 images can.

Hi mate.

Yes, this seems to function fine, resolution changes when settings modified as per this image attached.

I am using image Lcnc210_pi5 within image_pi5_rt.zip shared earlier by elovalvo
 

If you need me to install rods image to check the same thing, this is no problem.

Yes, my image uses debian so it won't have the pi specific menu options.. Some settings can be changed using  sudo menuconfig.
But if you could try adding
video=HDMI-A-1:1920x1080M@60D 
to cmdline.txt or equivalent, It would be helpful. If it works, I can add it to the installer.

Its still a pain because the Pi 5 needs to be at the bleeding edge of the raspberry kernel and the PREEMPT_RT is lagging behind that.

Ok looks like that might be based on a official Raspberry Pi image. Is there just one panel at the top ?

Yeap. I have one of these on the way

Edit. I find this the most awkward forum when replying to people.

I've gone for the Pineberry one

Latest RPi production kerenl (2023-12-05) is Linux kernel 6.1.63 for the most recent Raspberry OS Image,latest 6.1 series RT is 6.1.67, so it would not seem that the RPi 5 does not need a "bleeding edge" kernel, it's just there is a mismatch between latest RPi production kernel and the latest rt-preempt. If anything the preferred RPi kernel is behind the rt-preempt patch.

In actual fact the latest 64 bit image is the same for all models. After running a self (same recipe) made image for the RPi5 and using the official image and installing a RT kernel & linuxcnc, the official image appears to be a more "smoother & integrated" experience for the 5, tho I did change from Wayland to X so I could run a xfce desktop. The pre made images for the 4 are fine.

Although in saying that Rod if you have sources of info to the contrary I'd be quite happy to see it and amend my answer.

Yeah it was a toss up between the pineberry and the one I got. I chose mine because it was cheaper and had a cool design on the back haha, plus the company is a bit older.

Re:one panel at the top.. not entirely sure what you mean but I think you are right
