LinuxCNC on Raspberry Pi 4

OK went for an older build, 2022.01.21, and it does boot.

I'm confused, I thought the hardware was so standard it should yield consistent results. Could it be that the 8GB is somehow not going to run the one tested on 4GB? I can't say.

I got the 2022.01.21 Bookworm to boot, but username "pi", password "raspberry" didn't work. "user"/"live" and "user"/"password" also no-go. Checked caps lock.

I'm seeing that raspi.debian.net/ says it ships with no username/password set. But it's demanding those. Just hitting "enter" twice does not work.  I can't get a command line and don't see any way to continue yet

EDIT: turns out it's username "root", no password

Saw this so thought I would give bookworm a try everything went well until I ran my config setup. When starting Linuxcnc I received the error screen. Attached is error log file. Which contains the following error. HAL_PI_GPIO: ERROR: board revision 7 not supported. I have a RPI4 4GB.

The problem is due to the cpu_info.c file
github.com/LinuxCNC/linuxcnc/blob/master...al/drivers/cpuinfo.c

which refers to what is reported in this document:
www.raspberrypi.com/documentation/comput...ry-pi-revision-codes

To check what your Raspberry board revision is, see the result of the 'pinout' or 'cat /proc/cpuinfo' command executed in the terminal.

If the revision is present among those reported in the cpuinfo.c file, the version of linuxcnc used is not updated.
If it is not present, the file will need to be updated.

Let me know

Checked, cat /proc/cpuinfo
with the following output. Thank you for the help elovalvo, what next, looks like revision 3 which is there.

You forgot to report the last 4 lines that report revision information like this

That is all that there was to report i have included a screen shot.

 

Maybe this may help I started Hal and issued
loadrt hal_pi_gpio dir=246244 exclude=63444491

With the following results
