Hi kayige
First I’d like to ask about which docs are you following? I’d like to confirm that you’re using an up to date source.
There’s a sample app at GitHub - balena-io-playground/libcamera-apps: Example repo to showcase Raspberry Pi's new libcamera stack on balenaOS that you can use to check that the camera can be detected. Could you try to run this and see if it works as expected?
You can also use this as a reference. For example, check libcamera-apps/balena.yml at master · balena-io-playground/libcamera-apps · GitHub you’ll see that there are specific fleet config vars defined.
If that one doesn’t work, there’s also another app at GitHub - balenalabs/balena-cam: Network Camera with Raspberry Pi and WebRTC. Tutorial:
And also could you share which OS version you’re running? And if none of the above works, the result of dmesg would be useful
Cheers
Ramiro
