libcamera, DEBIX Model A, I/O Board, Raspberry Pi Camera 3 and 2.1 and Debix Ubuntu 22.04.5 LTS

[w.robertson at cairnwater.com]

I'm sorry to bother folk.

I got a DEBIX Model A with 2 GB of RAM, a DEBIX Model A I/O Board and a 
Raspberry Pi Camera Module 3

I followed the instructions for connecting the board and used the Add On 
board app to select the IO Board.

I tried installing dependencies using the instructions at 
https://libcamera.org/getting-started.html then getting the latest 
libcamera source and compiling but when I run

cam -l

I just get

Available cameras:

and nothing else.

I tried a Raspberry Pi Camera v2.1 but with the same result.

I also tried without compiling

sudo apt-get -y install libcamera-dev

and got the same result.

I can't work out what's wrong except that I downloaded Ubuntu from the 
Debix download page and that's given me Ubuntu 22.04.5 LTS - which is 
maybe too old for the latest version of libcamera?

Would it be better if i use a newer version of Ubuntu and configure the 
machine to use the I/O Board manually?

Here's the complete output:
