I just got the Arducam OBISP and tried running it on RPI3 with the PI OS running and kernel version 5.4.51-v7+. Installed the driver following the installation instructions. Get the following error in the kernel log:
arducam: disagrees about version in symbol module-layout
The driver then quits. No /dev/video0 there.
The documentation does not state what OS to use at all. Is it ubuntu or pi os. Pretty disappointed with the documentation.
