Cannot use bcm2835 SPI driver on Raspberry Pi 5

[Jaron123]

Hello, I'm trying to run your your weeny project on a Raspberry pi 5 using the pre-made linuxCNC distro file from the LinuxCNC website. I'm not sure what is causing the problem but running the hallcompile and install of weeny.c goes without problems. I have a bluepill STM32F103C8T6 programmed with weenyPRU-default.bin and wired them as in the weenyPRU v1.2 image on oshwlab website (Connected to SPI0).

When I then try to run linuxcnc with weeny-xyza.ini and hal example files i've gotten different errors at different times but it never works.

The first error I got was this:

linuxcnc weeny-xyza.ini
LINUXCNC - 2.9.1
Machine configuration directory is '/home/cnc/Downloads/weenyPRU-main/configsamples/weeny-xyza2'
Machine configuration file is 'weeny-xyza.ini'

Waiting for component 'weeny' to become ready..................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

Then linuxcnc won't shut down properly so I have to reboot, at some other try I got this:

linuxcnc weeny-xyza.ini

and
    /home/cnc/linuxcnc_print.txt
as well as in the output of the shell command 'dmesg' and in the terminal

and then at another try (Maybe this was after I rebooted after linuxcnc didn't shut down properly, not sure)

All I did was re-try after forcefully rebooting the pi after linuxcnc wouldn't shut down properly. i'm not sure the errors say anything usefull but hope you can help.

Oh and I wandered something, do I have to change anything to config.txt? I enabled SPI0 manually since it seemed only logical linux cnc would need it but it doesn't say anywhere in the documentation.
