Can't see v4l2 controls for Camarray Hat

  1. Where did you get the camera module(s)?
    I received the boards directly from Arducam after my previous ones broke.

  2. Model number of the product(s)?

  3. What hardware/platform were you working on?
    Raspberry pi 4 running Bullseye

  4. Instructions you have followed. (link/manual/etc.)
    Quick Start Guide for Arducam CamArray HAT Kit - Arducam Wiki

  5. Problems you were having?
    running v4l2-ctl --all doesn’t show the controls for the camarray. I also can’t manually adjust gain.

Also vlc doesn’t show any video output, but libcamera-still works.

  1. The dmesg log from your hardware?
 dmesg | grep arducam
[    9.677944] arducam-pivariety 10-000c: firmware version: 0x10003
[   10.177323] arducam-pivariety 10-000c: Consider updating driver arducam-pivariety to match on endpoints
  1. Troubleshooting attempts you’ve made?
    Redownloading drivers

  2. What help do you need?
    I would like to see the controls for the camarray hat’s gain, exposure, etc


Raspberry Pi is not directly through videoX

v4l2-ctl --all -d /dev/v4l-subdev0

vlc can’t get data directly
