New and Working RTAI debs for 2.9

BIOS settings are important. Have you looked at all the howtos for lowering latency?

La configuración del BIOS es importante. ¿Has visto todos los procedimientos para reducir la latencia?

Don't forget!

github.com/NTULINUX/RTAI/blob/master/README.BIOS

Thank you very much, I will try your advice.

To install on Debian 12 with linuxcnc-uspace already installed use : sudo apt purge linuxcnc*  and wait for apt to completely remove every trace of LCNC.

 

 

Trying to follow the instructions, but linuxcnc does not get removed and I get the following message when I issue  sudo apt purge linuxcnc*  

Package 'linuxcnc' is not installed, so not removed


Thanks

PhilipME,

Are you using a vanilla Debian install from their website? If so, LinuxCNC is not installed by default so you should be safe to proceed and skip that step.

If LinuxCNC is already installed (not run-in-place) then I'm not sure what's going on.

If you're ONLY using run-in-place, you can also skip the purge command as well, but do not try to use the run-in-place instance as it will not work with RTAI unless you've built it against the RTAI kernel debs that are listed in the first post of this thread.

I installed fresh copy of bookworm

Thank you and apology again for dump questions

It is working now beautifull

I had to issue sudo apt --fix-broken install

and sudo apt-get install python3-pyqt5.qtwebkit



 

Hey Philip, someone had issues with the 5.4.279 kernel, which RTAI kernel did you decide to go with?

If you don't remember or not sure, run:

I have started to set up LCNC with the RT kernel on my system (N3150 AMD630) running a fresh installation of LMDE6. I disabled UEFI and a list of other parameters as recommended eslsewhere, and used the download instructions at the top of this topic (the 5.4.279 versions).

At boot, if I select 'advanced option' I can select LMDE6 with Linux 5.4.279-rtai-amd64.

However, I get the following error:
bad shim signature
error: you need to load the kernel first.

I assume I have skipped something in the setup process. What should I do to correct this?

Update: This was fixed by (again) disabling secure boot - although it keeps saying it is enabled.
$ uname -a tells it is running rtai-amd64
There was a warning that the kernel was not compiled with ?? (message disappeared fast) but the system runs.
Now will try LCNC.

Update2: Switched Mainboard to A960D+ (6 core AMD), installed Debian12 and the rtai debs. Removed in BIOS anything not needed for a legacy setup. After setting isolcpu parameters (2, 4,5 - thanks for rt_setup.sh !!) got the best legacy timing ever on one of my systems: 6 - 8 uSec with 4 gears and a lot of browsing. Will test and apply the rtai version on my other systems as well.

Thanks and Regards,
Robert
