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-upgrade

  • rpi-update

  • I2C enables in raspi-config

  • The 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):

Trying on 32 or 64 bits raspbian: same errors / problems...

Any help / clue is appreciated.

EDIT

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.

i have the same problem with that kit. I run with Bullseye 64-bits. I did some researches to make it fonctionnal. ArduCam has their setup script and it made to work with Bullseye. The OS don't have /dev/video0 on the kernel and must be enabled with raspi-config. I thing to test individualy these cameras if they work...it is possible that ArduCam omits to tell that the camarray HAT has a driver to be installed to finally receive camera datas. Maybe buy more compatible cameras for my project to have colored images.

Would like to follow up having faced this problem.

Solution is to flash the Raspberry pi OS (Legacy-64bit) Debian Bullseye kernal rather than the newer Debian Bookworm Kernal. Follow https://docs.arducam.com/Raspberry-Pi-Camera/Pivariety-Camera/Quick-Start-Guide/#pivariety-cameras quickstart to enable cameras.

Tested working with 64gb sd card and raspberry pi 4b+ 8gb ram
