Systemd, udev, and kernel camera module

I'm currently struggling with systemd. We made a custom driver for CSI interface on iMX6, and we decided to move on systemd.


The main goal is to be notified when the driver is running and start our video application after that. I tried to modify udev rules and add:

KERNEL=="video0", SYMLINK="video0", TAG+="systemd"


and create a service for the video

Description=Video application service




The service never start. I don't know if I'm doing it right, but I don't know how to proceed exactly.


If you can give me some hints,

Thank you,
