LinuxCNC on Raspberry Pi 5

Category: Installing LinuxCNC

I'm new here. You guys are amazing to be honest.

On the fence about buying a Pi5 rather than using one of my existing PC's for my first controller, I guess I'll wait a few weeks (need to truck my new machine home) and see how we are going then.

Thanks again, what a great community here.

Only by building Linuxcnc yourself and patching the code for the hm2_spi driver.
I think it’s going to be a low priority for the devs unless someone who’s name ain’t mud makes some noise about it.

So mate it looks like it’s going to be up to you.

Does that mean we can use a mesa-spi card together with a rpi5? Tomorrow I will try mine (7c80). The image rodw made, looks and works promising!
On a Rpi4 a could not make use of USB3 speed together with my SSD, now I can!

Update to forum.linuxcnc.org/9-installing-linuxcnc...pi-5?start=20#285814

patched hm2_spi to force 8 bit words and driver does load.

What's the difference between hm2_rpspi and hm2_spi? As far as I know I only use hm2_spi.

edit:
answer:"The hm2_rpspi HAL driver does not use /dev/spi, instead it enables and
talks to the SPI hardware directly, so it works even if the Linux kernel
doesn't know about the SPI hardware."

But why shouldn't you use the linux-kernel for talking to your mesa card? Speed?

Going by my experience the Linuxcnc hm2_rpspi driver needs a rework. So far I haven't been able to get it to work. Hopefully it shouldn't be too much or require a major rewrite.

I have a Mesa 7C80, I will test SPI. Are there certain test-commands?
My Pi5 will arrive soon. I hope the 7C80 will give enough power for it. Only 2.5A according to the manual, and there is an SSD connected to it.

And then there are the Elo Touch drivers, hope they work too....

I didn't make life easy by buying a 7C80............... but it looks cool :-)

I've seen that message on my RP-400 but it still boots and runs fine.
I'm going to go out on a limb and judging by "seat of the pants" the RPi-5 is just about on par with a low-end x86 system that is capable of running Linuxcnc.

The patches haven't been causing any issues yet. My Pi has been on for hours at a time, compileda few kernels and did a 6 minute RIP build of Linuxcnc.
Once I sort the driver out I can run a few Configs. Sims seem to be ok.

Once I've sorted my issues out I'll test your image Rod. I'm not ignoring your efforts just need to sort things out at my end.

Yes, use X86. I have never used the Pi for linuxcnc. I did spend days trying in the past which is why I built ths installer so there was an easy way and none of the Linuxcnc devs had a working image.

As I mentioned in my woes post I had to force mesaflash to 8 bit word length as 32 bit wasn't communicating.

I reported on another thread.
Yesterday, I built a Pi5 version of the Official Linuxcnc image and shared it here
drive.google.com/file/d/1H_q0Ra-27ZDOhqu...x1f/view?usp=sharing
Upstream have included support for the pi5 but its untested due to lack hardware
Please give it a go and report back.
user = cnc 
password = cnc
run sudo menu-config to congigure wifi, locales, and user credentials
This time I added network-manager which should allow networks to be configured from the desktop

My concern here is I had to use the Raspberry 6.61 kernel to get Pi5 support but the latest RT patch is only for 6.54 so this could introduce bugs.

Also read today that the graphics drivers for the Pi5 won't b ereleased until kernel 6.8. I don't think that will be a big issue for CNC.

Love your work guys
Joco seems to be doing such a job job testing that I'm standing back a bit.

Once this is almost ready to run I can test it on my 6 ton machine.
