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

 

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

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.

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.

 

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

From the screen dump, you have nothing to upgrade so its not an issue.
That raspberry pi bug seems to have returned to Debian core code. Its not a Linuxcnc thing
SO the error is in relation to the  rasppi firmware it thinks is installed.

try sudo apt remove z50-raspi-firmware or
sudo apt remove raspi-firmware if it errors

Hi MR.Rodw
I same problem and try to your solution , but can't solve.
have any solution ?
Thank you

here you wrote "you tried this ... on a sim". I am trying to get *any* pi3/4/5 running on a sim - yet in vain. Could you shed some lights on hoe you got there, please?
My test environment

• OpenSuse 15.5 host (can change to what is promising, I am not stubbern, well my late wife used to say I was
  • 128 GB Ram
    • AMD 7900 or intel i9 13900
      • free disk space > 20T
        
        
        Aims:
        • Test environment for pi3/4/5 to improve the script here
          
          Any help greatly appreciated

With the RPi once an image is created that gets good latency it will work on any Pi of the same model.
EG A RPi4 image with known good latency user xxx creates will be the same for user yyy & aaa. The only factors that can make a difference is whether wifi\bt & sound are on or any personal changes to config.txt, but the Linuxcnc RPi4 image is usable out of the box. Unlike PC's there is no variance ( apart from which model) tho I don't know if firmware will makes any difference, but generally older firmware don't seem to boot the latest image. Good cooling is a must.
RP-400 (1.8GHz) have a faster Processor than a RPi4 (1.5GHz), although they are the same platform, just different form factor and the keyboard controller is built into the RP-400.
RPi5 is a different beast due to the RP1 I\O chip (read the Raspberry Pi's version of a southbridge).

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 Rod.

I used the iso a few pages back together with the raspberry pi image installer. I have never done any of this before so was surprised that it all just seemed to work without any issues.

From what I can see, resolution etc is working as it should, but please let me know if there is anything specifically that I can check for you.

My opinion is of limited value as I have not tried to drive a machine with the pi yet (card is stuck in customs) but over all it seems like a fantastic solution.

I understand that latency etc should not be a primary concern when using a mesa card HOWEVER I can tell you after trying four computers (with all the usual tricks) and getting poor usability and poor latency, this pi appearing to just simply work is 10/10.

Again, let me know if there is anything you would like me to check.

I have not used a Pi with LinuxCNC for some time now. From memory the most success that I did have was when using a Pi4 with images made by elovalvo from this forum. I seem to recall seeing him mention an image here recently.

You can find the references here:

forum.linuxcnc.org/9-installing-linuxcnc...xcnc?start=20#287208

forum.linuxcnc.org/9-installing-linuxcnc...b-pi?start=20#288227

im also confused about that. Is that a random error or could I have mixed up my linuxcnc OS with the raspberry pi version? I ran "sudo dpkg --purge raspi-firmware" and still doesnt launch.

Which method did you use to install Linuxcnc?
Have you noticed any issues with screen resolution?

Performance of the 5 seems amazing so far when stress tested and latency checked. Irrelevant as I have a mesa card but damn it seems like an easy solution for most people so far.

tomorrow ill try reinstalling linux with version 2.8.2, and testing it out on a raspberry pi 4. I understand my latency is worse than what you showed but only by 3-4x. I hope that linuxcnc would have some tolerance without freaking out over a small difference? at least to connect and start the program.

To be fair on the sticky for the image rod did mention the username & password on the 2nd reply on the second page.
