  1. The dmesg log from your hardware?

  1. Troubleshooting attempts you’ve made?
    Tried a fresh reinstall of everything. I have tried two different cameras. They both work on a Pi 4 (even though they freeze for a bit in OctoPrint, but that’s an issue for another day). The Ribbon cable I’m using is also from ArduCam, and I’ve tried multiples of them.

  2. What help do you need?
    .I need help getting passed step ‘libcamera-still -t 5000 -o test.jpg -n’/the camera being detected.

#2

It seems that there is no problem with the driver installation, and the camera has been detected normally.
From the error output of libcamera-still, it seems that the device is occupied by other software, maybe your mjpg-streamer is not closed?
You can turn off the default mjpg-streamer service and try to run libcamera-still.

Check service status:
sudo systemctl status webcamd.service

Stop the service:
sudo systemctl stop webcamd.service

Aufocus camera with Octoprint on Pi Zero

That fixed it. Thank you so much.
