Raspberry Pi v2 Camera

I have bought and connected a rpi v2 camera to the rock pi port. How can I test if the camera is
working ? I am on Armbian bullseye. Thanks!

You can use the radxa Debian desktop to test the imx219 camera. Just enable the device overlay in hw_interc.conf file by uncomment the following line:

 intfc:dtoverlay=imx219

Thanks. I am using armbian - how can I enable the radxa Debian desktop ? And, once I do, where would I find the file hw_interc.conf ?

You need to download the radxa Debian desktop image. The hardware configuration file can be found here:
