Raspberry Pi 4 Tutorial - fatal error

I'm on it, I'll report back. The problem is that all of these files have the same name. Who knows what's what?
By the way, it looks like LinuxCNC launched and actually ran with the other .img, but clearly something is wrong. I wonder if anyone is having luck running a 64bit version of linux on a pi4 and linuxcnc?
Cheers fingers crossed.

I just installed this one and tried. Same Error CPU 0 not supported! message...
I may head down the 64bit route since I'm having no luck with these 32bit installs or .img files.
Thanks!

Hi phillc54,
Yes, that's the file I installed.
The CPU error is what's baffling.

I got the same CPU 0 not supported message after downloading zip file to burn to sd card. See my other post today under Raspberry Pi thread. Can't seem to communicate to 7i76e ????????

Ah, at least I know I'm not crazy! It ran, but the latency was high. There is most certainly a problem.

There is a mention of cpuinfo here:
github.com/LinuxCNC/linuxcnc/pull/941

Thanks phillc54. I'm just learning this stuff. So a request was submitted to pull the changed code into the main code. When do changes make it out to the .iso file on linuxcnc.org/iso/ ? I see the pi4 iso's up there are from 9/14. Does these pull request merges happen once a week or on a schedule?

There is no schedule but you can follow this trail:

It was merged here:
if you do run in place then you can pull and build
github.com/LinuxCNC/linuxcnc/commits/2.8

It is still being built for buster i386 and amd64 but the armhf package is built:
see bottom right
Edit: it has finished...
buildbot.linuxcnc.org/buildbot/grid

It is available for armhf here:
buildbot.linuxcnc.org/dists/buster/2.8-r...inary-armhf/?C=M;O=D
so you could update now
Edit: you can if you have Buildbot set as your repositery

Oooooola! My very own buildbot!
I don't know what that is, but I'm on it...

Er, well dang, it's a bit over my head to compile the .iso myself. I tried to find a walk through but can't. It's OK, I can wait a bit.
