Raspberry Pi 4 with PlasmaC

That is in cmdline.txt

OK, here we go again as per your details.

You could change cmdline.txt from root=PARTUUID=738a4d67-02 to root=/dev/mmcblk0p2 (I think)

Sorry, now only the color splash. This has to be PARTUUID that point wrong.

Here is my complete SDCARD image, it is Buster with the Mate Desktop and LinuxCNC 2.8 from the Buildbot

drive.google.com/file/d/1t0I-ZGmg5sghqny...6hS/view?usp=sharing

EDIT: Image has changed forum.linuxcnc.org/plasmac/39179-raspber...smac?start=80#170904

username is pi and password is 1234 there is also a phill user with the same password that you could delete.

You will need to resize it after boot, raspi-config is available from the menu in System > Administration

I link the ~/linuxcnc directory to a NFS mount so after booting you would need to edit /etc/fstab and remove/edit the line for 192.168.0.100 and you would also need to delete the existing ~/linuxcnc link and create you own linuxcnc directory or link.

There is also a ~/git link which will need removing.

So now it gets a bit in to boot, after DHCP it scrolls so fast with text I cannot read and goes black - dark grey - black - dark grey and stops no cursor no nothing.

It gets this far ...... approx 1 minute in to boot

Maybe it has something to do with that fact it cannot connect to the NFS shares. I will make one tomorrow that doesn't try to do that.

Yes it looks like its looking for something.

Works that far with root=/dev/mmcblk0p2

I really appreciate your help with this!

Did you try the complete image?
