Turned out the /dev/video0 device was missing due to the special port mapping that we were using. The problem was fixed by adding "cam0_reg","cam0_reg_gpio=30"
to the DT parameters for the default overlay in balena. From there on the solution was the same as #270.
I'm posting this here as a reference, but I doubt it will be useful for anyone else since this issue was caused by our special port mapping.
Describe the bug
We are experiencing a very similar issue as https://github.com/raspberrypi/libcamera-apps/issues/270. There is only one difference: the solution does not work :cry:.
So the
libcamera-hello
utility does not detect the camera:Bug report
I used:

Additional context
The system is a compute module 3, an imx219 camera, the latest version of the balenaOS (balenaOS 2.108.18+rev1).
I run the libcamera-apps in a docker.
The content of /mnt/boot/config.txt on the host is:
The content of /mnt/boot/cmdline.txt is:
I've also tried these:
dtoverlay=vc4-kms-v3d
dtoverlay=imx219
(the cam0 is because our compute module has a specific port mapping, but also wanted to try this).I've also tried to:
video
group.UDEV=on
and runudevadm control --reload
in the docker.BALENA_HOST_CONFIG_camera_auto_detect=1
like suggested at the bottom of the related issue.The output of
v4l2-ctl
:I would lope it if you can help me! :star_struck:
