LinuxCNC on Raspberry Pi 5

After going through this thread, it seems that the current RPI5 image on the download page should be sufficient to get a usable RPI5 OS install.

I have been working to install the image on a new RPI5 with a Pimoroni NVME installed. I've tried installing on both the SSD and the SD Card. In both instances I end up with no network connection (neither Wi-Fi nor Ethernet) and no network configuration utility under settings.

What additional steps I need to take?

Thanks,

Randale

...For my final design, I will add a 4,700 or 10,000 uF/ 6.3 V (or 10V or 16V) electrolytic across the 5 V rail (close to the Pi power input) because I have noticed that plugging in the Mesa card causes the Pi to reboot. The Pi evidently has very little on board power supply capacitance.
 

Just be careful not to exceed any "maximum load capacitance" of the supply.  All switching supplies will oscillate (or worse) if loaded with too much capacitance.  Sometimes this limit is mentioned in their datasheet, sometimes not.  If you can access an oscilloscope, 'scope the power to ensure there isn't any ringing or other oddness happening (this can be in the MHz range, completely invisible to multimeters.)

Hello.
I'm newbie linux and RPi5.
I did the connection with the Mesa card.
I also have a 10.1" IPS Touch display with resolution 1920x1200 @60 Hz + audio speakers.
But there is no sound, the resolution is only 1920x1080, no possibility to rotate the screen and can't find the grub (/etc/default/grub in sudo nano says it's a new file).

I'm hoping for your help.

Raspberry Pi doesn't use grub
Resolution is a issue with this image
You may have to enable sound see

You can try with the image for Pi5 (Lcnc292_pi5.img) that you find at this link:

Is it possible to solve the resolution issue with the rotation?
I have tried the config.txt, but without success... what did i wrong?

How to use this image, to configure it?
Is there a step by step instructions?
There are a lot of Youtube videos, but none helps with this image...

You'll have to look around in /boot

Sorry should have mentioned that.
