Hi!
Just some regular CNCer, already proficient with my rpi4 8gb and 2.8. I thought I might try something else, test some stuff. Been reading around here for some days now. I tried to run that image (the one from Rod's first post):
rpi-4-debian-bookworm-6.1.54-rt15-arm64-ext4-2023-10-21-1847.img
but it gave me that screen (see attached file). Seems to be hardware related...

Yes, I get that error too on my older Pi 4b
Lots of others have it working for them.. Just hardware I think

Any work around? Switching to a x86 computer?

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.

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.

Is this a different image than the one on the downloads ,link below? I am unable to get one linked below to work with my mesa 7i76e, I keep getting following errors even with the servo thread set to 2ms. I had the same config working under 2.8 on the same pi 4b. I remember having to set the system to stay on one core to get it working, is that still needed?
-Thanks

The image I built was copied to linuxcnc repos so no.
The later one of mine has some changes around repositories and also added network manager because guys were complaining bout not being able to easilly set the wifi settings (which can be set in menu-config anyway)
2.8 used a 32 bit kernel, this is 64 bit
All of the isolcpus settings are already done for you.
Lots of guys are using this with 1 ms servo period without following errors.
Following errors are related to your tuning, error finishing read is a hardware issue which is a kernel problem affecting mesa cards but we have not seen reports of that on the pi.

Thanks for the info and the time you put in making the PI image. I must just have a bum pi4, I get the sculls error at boot but it boots up and runs. I downloaded the image you have linked to this thread and loaded my config after setting the network interface to 10.10.10.1 and leaving wifi off, I ran it for a bit and I got realtime servo thread errors and then the joint following errors, same config runs on my I5 Intel NUC. I wonder if my pi is is overheating or has some other hardware issue. I need to find another pi4 and try again. Thanks!

Checked that the governor is set to performance.
But yeah if it is overheating it will throttle down. A heatsink\fan might help.
But if the NUC is ok I'd stick with that.
