Thank you for the explanation.
But if this is not possible, I am wondering how people are supposed to use the 7C81?
Because to be very honest I don't care what kind of Linux/Ubuntu version I would need to use, I just would like to get my CNC machine running by using the RPi in combination with a 7C81...
So any advice on how to achieve this is very much appreciated.

I think using Raspberry PI OS is the easiest way
as it look like Debian has poor or completely missing
SPI support on the RPI

But how do I do that?
Because all the installation instructions on the internet are either aimed towards the plug-and-play file from the LinuxCNC frontpage (but this file is not compatible with RPi's that have been manufactured in the past 2 years), or they follow the instructions from Rodw (like I did yesterday but apparantly isn't working):

Did you try the official RPI image?
Anyone know if it has SPI support?

I just installed Raspberry Pi OS with the Raspberry Pi Imager tool.
But I don't know how to proceed from there, as for example the commands below are not recognized:

Hey Stef, you can try these images
github.com/Expatria-Technologies/remora-flexi-hal/releases
www.forum.linuxcnc.org/9-installing-linu...cnc?start=150#253623
They will be plug and play.
The official lcnc rpi image does support spi, ive used it before with mesaflash
edit, stef, do not worry. I have several 7C81 boards. If it were not for the RPI image mismatch, everything wuld be good. The linuxcnc rpi images are surprisingly turn-key, just the official one has fallen to the wayside. I havent tried the expatria one with a mesa, but I am using elvalvo's RPI images and 7c81 with very much success.
