Alan, The steps below From Peter Wallace compile for realtime. Change the kernel to suit. In xconfig you need to set fully preemptible kernel to yes. I think that could be done from the command line to fully script it if you know the kernel config stuff. If you are not using root to build the kernel, the sudo password timeout can be disabled. See https://wiki.archlinux.org/title/sudo#Disable_password_prompt_timeout I think this should still work on debian
There is a repo somewhere with a method to build a preempt_rt kernel for the RPI4. But the RT kernel should be in the debian repos I'm presently running archlinux on my problem realtek NIC based machine where the packaged kernels are fine. Last night, I devised a method to install linuxcnc from the debian bookworm packages. I'll try that today... mkdir rtlinux cd rtlinux wget git.kernel.org/torvalds/t/linux-6.1-rc3.tar.gz wget https://www.kernel.org/pub/linux/kernel/projects/rt/6.1/patch-6.1-rc3-rt2.patch.gz tar -xpf linux-6.1-rc3.tar.gz gunzip patch-6.1-rc3-rt2.patch.gz cp patch-6.1-rc3-rt2.patch linux-6.1-rc3 cd linux-6.1-rc3 cat patch-6.1-rc3-rt2.patch | patch -p1 make xconfig make -j $(nproc) sudo make INSTALL_MOD_STRIP=1 modules_install sudo make install Rod Webster *1300 896 832* +61 435 765 611 Vehicle Modifications Network www.vehiclemods.net.au On Sun, 13 Nov 2022 at 01:42, Alan Condit <condit.a...@gmail.com> wrote: > Andy, > > I can’t do it either, but I really appreciate all the help you've given to > LinuxCNC. > > I agree that Bullseye would be an appropriate target for the 2.9 release.
