Comparison between Raspian 12 Bookworm on Raspberry Pi 4 and Raspberry Pi 5

No, the images are different.
If you wait a couple of days I can create updated ones for both versions of Raspberry

Here are the files I promised you

drive.google.com/file/d/1jBEO7Acl0C0t4id.../view?usp=drive_link  (Pi5 - kernel-6.6.32-v8-16k-elv.zip)

drive.google.com/file/d/1B58q4xJgBR4GnxI.../view?usp=drive_link  (Pi4, Pi400 - kernel-6.6.32-v8-elv.zip)

drive.google.com/file/d/1ltrkbEiI_BssNY0.../view?usp=drive_link (install-kernel)

Since for building the RT kernel I followed this procedure ( forums.raspberrypi.com/viewtopic.php?t=343387 ), in the next post I describe the procedures for using.

To install raspian12 bookworm image, prepare an SD card with the RaspiOS version for the type of Raspberry you are interested in (pi4, Pi400, Pi5).
I find it comfortable
www.raspberrypi.com/software/
because it also allows you to select various options (ssh, wifi, locales, etc..).

Boot the SD and run these commands from the terminal to update the RaspiOS version


Upon reboot, copy the install-kernel files and the zip file to the /tmp directory

Then run these commands from terminal


(in the case of Pi4 and PI400)

or
(in the case of Pi5)

So you need to edit the cmdline.txt with adding the following commands to the end of the line
isolcpus=2,3 rcu_nocbs=2,3 nohz_full=2,3 max.processor.cstate=1

alright, awesome thank you!

question, your previous images had the rt already installed, is there some limitation to why they arent this time, or is it so you can hit update before loading the kernel?

I chose this procedure because it allows you to choose the best Raspbian configuration (user, password, ssh, wifi, locales, etc..), to update an already existing version, to install the version of LinuxCNC of your choice and other alternatives.

However, for those who don't want to, in these links there are the ready-to-user images with LinuxCNC 2.9.2

Another note if you want\need to run Axis you’ll want to use raspi-config to change from wayland to x11. Or anything that depends on the X11 libs, I found the way land compatibility layer really really slow.

Awesome used all of elovalo bits to setup an Rpi5 with Pineberry NVME hat, works great.
