Hi @MarcBresson Currently we only provide the pre-compiled kernel driver of the official SD Card image. Because it is relatively fixed (it may be updated every few months), but the kernel version you update with rpi-update will be updated every few days, we cannot provide pre-compiled drivers for each version.

Since we provide the source code of the kernel driver, I suggest you compile the driver of the kernel version you need with our documentation. https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/how-to-install-kernel-driver-for-pivariety-camera/#ftoc-heading-10

The kernel 5.10.52 is actually the new default raspberry pi image version. It is no longer 5.10.17

furthermore, i do have an issue with the driver compilation. libcamera-vid is working fine, but libcamera-still gives me an error (full thread here https://www.raspberrypi.org/forums/viewtopic.php?f=43&t=317401)

Hi @MarcBresson

Thank you for the information, Regarding libcamera-still, can you try to run libcamera-still locally instead of using ssh? Or execute the following command: libcamera-still -t 0 --viewfinder-width 1920 --viewfinder-height 1080

MarcBresson commented 3 years ago

Executing the command locally still gives me the same error. Furthermore i'm running a headless raspberry pi, so i guess viewfinder isn t doing anything (yet, this command did not generat any rror, but was just doing nothing)

Hi @MarcBresson

This seems to be normal behavior, and the function of this command is to preview the image indefinitely...it doesn't do anything else. If you want to take a photo, you can execute: libcamera-still -t 5000 -o test.jpg --viewfinder-width 1920 --viewfinder-height 1080

-t 5000 means wait for 5s (for preview and ISP adjustment parameters) you can reduce it. -o test.jpg means to output an image named test.jpg.

yeah it is working ! thank you. any idea why when we omit this two options, there is an error ?

This may be related to your headless system, you can try to use the -n parameter instead of the resolution settings. (-n means nopreview)
