Will this work on Bookworm and Trixie?

[nafanz]

Hi. Has anyone tested this to see if it will work on newer OS's? Do they require any adaptation?

• Raspbian GNU/Linux 12 (bookworm)
• Raspbian GNU/Linux 13 (trixie)

I just did a setup on a brand new installation of RPi-OS 13 on a brand new Pi Zero 2W board. I didn't do any customization of the installation image at all.

The Ansible Playbook runs fine (run trough SSH from my desktop rig, not locally at the Pi), and this is what I get on the logs of the SystemD unit: journalctl -u piwebcam.service:

As you can see, it tries to open /dev/video1 as output, but it is being used.

Here is the output of v4l2-ctl --list-devices:

I was wondering the same thing. I have a few Zero Ws and 2Ws that I would like to use for this, but can't seem to get them to work.
