RPI4 Raspbian 64 bit & LinuxCNC

I think it'll be better to just have one image, support will be easier. Well just my opinion.

We are using the Raspberry Pi repositories. Debian it is! Thats what they give us! Thats what we use!

I thought you were talking about people building their own images. I have a feeling that some peoples only use of Linux is for Linuxcnc and that maybe the only exposure they have.
I'm running the image builder on Mint as I just couldn't be bothered installing Debian or Ubuntu on my main machine just to build images.

Sorry there. My intention is to get this accepted as the official rpi builder for linuxcnc to replace this old one github.com/LinuxCNC/raspberrypi-linux   I don't think its even 64 bit. But ideally, it will be fully configured, ready to go and just using the user configurable features so there is no hacking into any core scripts.

There has been so many images shared around but some are dated and the build process is never shared and its never been based on the official builder like this one.

I'm building another image for the x86 I have to get back to. Its been reviewed by one of the main developers so it needs a couple of things polished.

But what excites me is  C0nelius upstream has another more generic ARM image builder so I'm keen to gve it a go for my 6 core Odroid N2+ which is gathering dust.

Excuse me if I've got this all wrong... but isn't the goal to produce an img for a RPi that can update this one:

www.linuxcnc.org/iso/linuxcnc-2.8.1-pi4.zip

linked from here:  linuxcnc.org/docs/html/getting-started/getting-linuxcnc.html

100% agree that a documented method of building such a thing is most useful but for 99% of folk a simple install-it-on-my-RPi in the normal manner is what they need.

FWIW after a couple of hours testing , Cornholio's latest seems very close to achieving that aim.

The 'normal' Raspian stylee dd from the SDCard to a USB SSD doesn't result in a bootable USB device but sticking Cornholio's .img on a USB SSD does boot... but didn't auto-resize the root partition a parted and resize2fs sorted that (no not idea but it worked!).

Apart from that I'm struggling to find issues but I'll keep playing with it.
 

Well, yes. my goal is to be able to have an image for the Pi based on Bookworm that can be used when they release Version 2.9. Deploying the resulting image on the web site is a task for the devs. But its likely to be driven by an automated buildbot. The current buiildbot for bullseye and bookworm does not build debs or images for the pi. The oldbuildbot uses a pi and its not been very reliable. It crashes once  a month and brings the whole buildbot down. This runs on a cross compiler so should be more robust and produce the debs as well as the image.
I'm just trying to remove some roadblocks so 2.9 is released sooner than later.

I thought the "normal" Raspberian style would use rpi-imager  www.raspberrypi.com/software/
Balena Etcher is also an alternative which runs on any platform and is way faster than dd
