LinuxCNC on Raspberry Pi 4

So, where is this at? Is there a version of LinucCNC that works on the new rev of RPi 4?

If you are looking for a ready-made image, tested with Rasperry Pi 4B (2GB and 4GB) and Pi400, you can find:

- the Buster-based 32bit version with LinuxCNC 2.8.4 here
forum.linuxcnc.org/9-installing-linuxcnc...erry-pi-3b-pi#260915

- the Buster-based 64bit version with LinuxCNC 2.8.2 here
forum.linuxcnc.org/9-installing-linuxcnc...-4-8gb-2gb?start=50# 255092

- the 64bit version based on Bullseye with LinuxCNC 2.9.0pre here
forum.linuxcnc.org/9-installing-linuxcnc...cnc?start=150#253623

Also there are numerous links on the forum describing how to create your own image on different distributions (Raspi OS, Debian, Ubuntu, etc):

forum.linuxcnc.org/9-installing-linuxcnc...-bit-linuxcnc#230690

If you wait a few days, I'm preparing an experimental one with 64 bit, with Debian 11 (Linux 6.0.09-rt14) and LinuxCNC 2.10.0pre

But that's the one that just says "this board requires newer software" and won't boot with the current rev of RPI 4 board.

And this one says "Welcome to Raspberry Pi Desktop" splash screen, but then the monitor says the HDMI signal is lost and it never recovers. Hitting the keyboard had no effect.

What version of Raspberry do you have?
What are the answers to these terminal commands?

cat /sys/firmware/devicetree/base/model

cat /proc/cpuinfo

A new ready-made image is available, with the Buster-based 64-bit version of LinuxCNC 2.8.4, tested with Rasperry Pi 4B (2GB and 4GB) and Pi400

It doesn't work on Raspberry Pi3B+
