Hi guys, could you guys with the PI's please test these images for me and provide some feedback
These are refreshes of my earlier 2.9.1 images.
They both use the latest PREMPT_RT 6.1.69 kernel, and Debian Bookworm

Raspberry Pi 4b/400

Also, those of you with the Pi5, have you had any issues with sound. One user reported he had no sound but the HDMI output is a bit poblematic. The images do include pulseaudio.

Hi,
here is the translation:

The input file is not a valid disk image.
The file size 4723000000 bytes is not a multiple of 512 bytes

It appears that there is something about our image that the Rpi Imager does not like.
The guys are working on it.
Could you please try burning with Balena Etcher? etcher.balena.io/
This burnt and validated the image for me.

Great! Please test it out a bit and give me some feedback

It seems that we are using a slightly different compression method that the PI imager does not like.

Hi,
I have tested it a bit on my lathe with gmoccapy. So far so good. With my old iso I had some latency errors they are gone. The audio error on raspberry pi 5 persists.
And I can't move/rotate the gcode viewer with touchscreen.

Balena works well.

Screen resolution works so much better than anything I have seen so far. Jitter is good and sim looks smooth.

Problems, I have no sound, no Wi-Fi, no network manager and no update manager.

Thank you for all the work.

Scott,
Please read the Linuxcnc downloads page.
Typing: sudo menu-config
allows you to set wifi and locale etc.

Configuring fixed ip address etc for ethernet card, can be done manually as described if you type: man hm2_eth

We removed networkmanger I had added it in and latency suffered on the pi4b

If you really need to use it, you can install synaptics: sudo apt install synaptic 
I prefer to search for the package names in Debian Package search packages.debian.org/index
and use sudo apt install package-name

When you say you don't have sound, this is  a known issue, one of the upstream guys was going to review that for me as its a limitation of their installer. Their first priority was to fix the compression settings so it can be installed with rpi-imager.

I don't think it will be wise to use sudo apt upgrade becasue we have a custom built PREEMPT_RT kernel we have built from source using a kernel version not in Debian Bookworm..

Note the ethercat repos are installed if you want to go that way.
