IMX519 Slow Focus Pi 5

Raspberry Pi Cameras
1

Is PDAF enabled on the IMX519 with the Raspberry Pi 5? If so, what are the steps to make it work on the latest version of Raspbian.

On a fresh install of Raspbian OS Lite 64 Bit (6.6.31+rpt-rpi-2712), I did the following:

wget -O install_pivariety_pkgs.sh https://github.com/ArduCAM/Arducam-Pivariety-V4L2-Driver/releases/download/install_script/install_pivariety_pkgs.sh
chmod +x install_pivariety_pkgs.sh
./install_pivariety_pkgs.sh -p libcamera
./install_pivariety_pkgs.sh -p libcamera_apps

The autofocus is incredibly slow (10+ seconds, and appears to be CDAF). Turning on autofocus debugging shows that the PDAF confidence values are zero.

Here is a real time video of the autofocus (continuous) in action streamed directly from the camera. As you can see it seems to be using the course step/fine step algorithm which is part of the CDAF fallback.

Hi @Nighthawk
You can stay tuned to the issue opened in the Raspberry Pi GitHub. It has not been solved so far.

Thanks! I will do that.
