Could not open device node /dev/video0. ToF

Raspberry Pi Cameras

I followed the official tutorial and got the following results.

open ***WARNING*** Could not open device node /dev/video0. Please check for permissions.
initialization failed

I can see some similar reports but could not find a solution.
What I did:

  • Auducam-Pivariety Driver update
    sudo apt install arducam-pivariety-sdk-dev
  • check /boot/config.txt
    dtoverlay=arducam-pivariety
  • does the driver exist
    /boot/overlays/arducam-pivariety.dtbo
  • check dmesg 
[   10.479222] arducam-pivariety 10-000c: pivariety_read: Reading register 0x103 failed
[   10.479244] arducam-pivariety 10-000c: probe failed

Hi
You seem not to refer to a correct guidance.

Delete this sentence in the config file and then follow the link below to install relevant dependencies:
