Yes it’s the preemept-rt kernel. 32 bit though not sure you gain much from 64 bit here.

It’s pretty plug and play I’m running my plasma table on it currently.

I install the image, my raspberry starts, but it remains blocked. I have neither access to the mouse nor to the keyboard, nor to the tacrile screen.

Did you have this problem ?

Thank you

Do you have 8G of RAM? There's a known USB issue with
that version. I think it needs a newer kernel than on the LinuxCNC
image.

I'm tempted to pick one up - which version do people recommend?

I do not know at all .
You think that the difference of "Ram" can have a difference to such an extent that the raspberry remains blocked?

Hello ,

i built on u amd64 linuxcnc 2.9pre with switch kin branch. It works very well.

Now i want to make it all work on raspberry pi4

I'm trying to install a 64-bit Kernel Preemt-rt on my RaspPi4.

: www.instructables.com/64bit-RT-Kernel-Co...or-Raspberry-Pi-4B-/

works well, until the moment when it no longer happens on a simple file copy.


Can you help me please because I am not very easy in the matter.

thank you so much


The boot directory in rt-kernel is probably missing.
run this commands:
mkdir ~/rpi-kernel/rt-kernel
mkdir ~/rpi-kernel/rt-kernel/boot
