    raspberry pi 4 8GB

  4. Instructions you have followed. (link/manual/etc.)

  5. Problems you were having?
    I try to set the autfocus mode in python through the picamera2 library, by using
    “AfMode”: controls.AfModeEnum.Continuous. I recieve the following error:

Note this exact script was working before upgrading the kernal and having to reinstall libcamera and libcamera-apps

  1. The dmesg log from your hardware?

I fixed the error by modifying /boot/config.txt

I originally had:
[all]
dtoverlay=arducam_64mp

and changed this line to:
[all]
dtoverlay=arducam-64mp
