Linux: Vision SDK - UC:( camera + Display Server) -running disp-dist-server & apps.out binary via systemd

Tool/software: Linux

Hi all,

We are using systemd to launch services.

We are launching in below order

1.Pvrinit

1.load-video-modules 

2.disp-dist-server                       

3.vsdkapps (apps.out)

4.Weston

5.Hmi

 But this doesn’t work if don’t insert 2 seconds  delay between disp-dist-server and vsdkapps and Weston

 Working sequence. 

1.Pvrinit

1.load-video-modules 

2.disp-dist-server         

   2 sec delay             

3.vsdkapps

    2 sec delay

4.Weston

5.Hmi 

This delay is not acceptable for our startup requirements. dmesg is not printing anything when disp-dist-server and vsdkapps are started.

 Is there any interfaces added when disp-dist-server is ready and vsdkapps is ready.

If there is an interface we can wait for that interface to start services.

 Please suggest.

Regards,

Gokul
