I have the same problem with 32 bit version of Raspbian on a Pi02

Feel sorry,
The arducam driver source code on github is suitable for 5.10.y, some modifications are needed for 5.15.y, you can try the source code in the attachment.

Why don’t you update github?

5

We’ve recently been preparing to commit the Pivariety driver to the Raspberry Pi’s linux kernel, so haven’t updated it yet.

Thank you. That fixes the compilation problem.

If anyone is interested in the process of submitting arducam-pivariety to the raspberrypi linux kernel, you can see related information here:

Once installed, should

sudo vcgencmd get_camera

detect the IMX519 camera?

9

No, vcgencmd get_camera is used by the legacy camera stack.
libcamera doesn’t use it to detect cameras, you can try using:
libcamera-still --list-cameras
Or to see if there is a video device:
ls /dev/video*
Usually /dev/video0 and /dev/video1 should exist
