IMX477 camera mmal issue


Our original idea is to use a raspberry pi 3 or 4 to make a stereo picture. We also would like to sync the flash to take the picture but this is another problem.

We set up the kit, connected the camarray hat and the two camera with the flex cabels.

The problem is that we cannot get a preview window or take a photo or video at all. We followed the tutorial and set the needed parameters at the /boot/config.txt, enabled the camera, but it did not work. At first neither the raspistill nor the libcamera worked. We tried the buster and bullseye operating system also but we got an mmal problem. After some trying we managed to make the libcamera work on a bullseye operating system, but we would rather use the raspistill command line tool because we found that we could make the flash syncronization work easier with the raspistill and it is more flexible and parametrizable for us.

I read a lot up on it and it seems thet only the x32 architecture is supported, so we only used 32 bit operating systems.

We also tried only the raspberry pi HQ camera with directly connected to the raspberry pi and make the raspistill working, and it is working fine luckily but we need a stereo photo not a single one.

Here is the exact error message:
mmal: Cannot read camera info, keeping the defaults for OV5647
mmal: mmal_vc_component_create: failed to create component ‘’ (1:ENOMEM)
mmal: mmal_component_create_core: could not create component ‘’ (1)
mmal: Failed to create camera component
mmal: main: Failed to create camera component
mmal: Camera is not detected. Please check carefully the camera module is installed correctly

Could you please walk me through the correct stepps which are needed to make it work? At first we would like the raspistill to work with the plain rpi HQ camera.

*Side note: We also tried to make the stereo camera on a jetson with the appropriate - jetson supported - camarray hat, but it also does not work.

Best regards,
