I have a Raspberry PI 4 B 8Gb. I have this kit (2 ov9281 cameras with camarray hat): https://www.uctronics.com/arducam-1mp-2-stereoscopic-camera-bundle-kit-for-raspberry-pi-nvidia-jetson-nano-xavier-nx-two-ov9281-global-shutter-monochrome-camera-modules-and-camarray-stereo-camera-hat.html.
Trying to get images from ov9281 cameras with RPI4 doesn't work: I get ERROR: *** no cameras available ***
All steps I did try are listed below:
Fresh rapsbian install
apt-get update && apt-get upgrade && apt-get full-upgrade && apt-get dist-upgraderpi-updateI2C enables in
raspi-configThe camarray hat is plugged like explained here (red light turned on, alimentation OK): https://www.youtube.com/watch?v=UN4ZBttQwdI. The camarray is plugged on pins 1-2+3-4+5-6 described here https://pinout.xyz/

Any of the different tested overlay doesn't work (arducam-pivariety, ov9281) after reboot. In particular this camera-mux-2port (https://forums.raspberrypi.com/viewtopic.php?t=339339) doesn't work neither.

After all this has been done reading the docs (arducam, raspi, etc), I still get this error (what ever libcamera-hello is build from source [https://github.com/raspberrypi/libcamera-apps] or the ones provided by the upgraded system):

git clone https://github.com/ArduCAM/MIPI_Camera
Does not help!... My understanding is that ArduCAM is the old software used before bullseye: link KO in 32 bits OS (undefined reference) and KO (incompatible libs - code looks like to have been generated on 32 bit arch) in 64 bits.
