LinuxCNC on Raspberry Pi 5

I have made a mistake. I thought the kit I bought gave no *physical^ access to the SD card. But, it does.
My apologies for the trouble and misunderstanding.

hahaha

These things happen.

We're making some headway towards getting a 6.12 kernel going with rod's image builder.
But despite what the recent skuttlebutt suggests for arm platforms it seems that some patches are still required for realtime.

Is there a GitHub tracking thread (or something else) for those patches?

I would be really interested in following that thread.

These are Linux kernel patches, so I guess where the kernel devs hangout.

Hi all, 
after swapping our Raspberry Pi4 with a 5 things didn't work anymore as they did before, and thanks to this forum, as far as I understood there is no SPI support yet, right? 
I have also read that "rodw" you have created an image builder, and "Cornholio" you managed to patch it so it works right?
As we are trying to run the mesa 7c80 with a Raspberry Pi5, is there an image available currently that supports this combination? If not what would be the steps to "patch" it together? 

Thanks a lot in advance 

The 7C80 will work with the RPI5 using the hm2_spix driver.

Note that some 7C80s were shipped with firmware that does
not work with the RPI5. These cards can be re-programmed
on a RPI4 if that's convenient. All the distributed bitfiles are OK.
 

The biggest issue is that Linuxcnc will require building from source as the RPi5 images don’t have Linuxcnc packages built from the most recent code base. Editing config.txt to turn on spi is a trivial matter.

Give me a day or 2 and I’ll generate an image with the most recent Linuxcnc & Mesaflash.

Wow, thank you @cornholio! That will make it much easier for us
@PCW thank you as well for the info.

6.1.69 Fully preempt kernel
SPI enabled by default
Linuxcnc 2.9 built from git repo today just uspace & dev packages no docs
Mesaflash built from source today, version 3.5.10
Instead of xfce I built the image with Mate, std debian config looks different to std Mint install.





Tested mesaflash to just get the pins from my 7c81 clone tested ok
Test loading the hm2_spix driver for the rpi via a halrun session ok
Quick latency test ok

Thank you! Will try it out on friday.
