RPI4 Raspbian 64 bit & LinuxCNC

The real time is inside ?

thank you

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

Nope everything boots and works great right out of the box.

There’s a video of my table running on a pi

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.

Hello ,
No I have 2Go of RAM

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?

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

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
