LinuxCNC on Raspberry Pi 4

 I flashed LinuxCNC 2.8.1   Raspberry Pi OS based on Debian 10 Buster  on a card and tried it on a RPi400. When I first started it there were a message that the CPU is not supported but it started anyway and everything seemed to work (exept wi-fi) until I should shutdown the RPi400. I couldn't shut it down, it always restarted. What does this mean?

Many regards,  malare

If you need to use version 2.8 (64-bit) you can take the image you find here.
forum.linuxcnc.org/9-installing-linuxcnc...cnc?start=120#224608

LinuxCNC also works on raspi400 (I have one and have checked) but the version is not the most recent and therefore the hal_pi_gpio driver does not work.

If you want to use version 2.9 instead you can use the image you can download here

I am expecting to release a 2.8.3 fairly soon. Would you expect that to fix this? Or is there more to do?

Yes, the new version will solve the problem.

My observation is due to the fact that the correction of the hal_pi_gpio file is dated 21 March while the SD image to which the link refers dates back to October 2021


One question: Will version 2.8.3 still be based on Debian Buster or will it use Bullseye?

It will be a re-spin of the current ISO, possibly with a couple of packaging fixes. 

The third line of your comment... the link is now broken. I think you may have meant the buildbot page at buildbot.linuxcnc.org/ , but can you let us know if that's not what you meant? Thank you!

Dang it, I'm trying to respond to elovalvo's comments on Feb 28, but it keeps posting to the end of the thread. Sorry
