show image on HDMI & composite display at board boot up as well as shut down time



Hello All,

 

We have a customize board based on DM814x and we are using RDK 4 on it.
We are giving
    1] 8ch capture + encode + dump (mp4 + JPEG)&
    2] 8ch capture + display support.

 

I want to show image on HDMI & composite display at board boot up as well as shut down time.

What I have to do for this?
