DRA77P: Early HDMI initialisation

Part Number: DRA77P
Other Parts Discussed in Thread: SYSBIOS

Hi,

I am working on TDA2Px SoC and using vision SDK v3.07.

We have a particular application in which the apps.out has to display the camera outputs in 4 sec. HDMI is the display used.

Since links and chains are used various cores comes into play for the processing of data captured from the camera and also A15 core is a part of the processing.

We are able to launch apps.out at around 4 secs in linux, but display is shown after several secs. So we have decided to place a log screen displayed via HDMI in order to cover up the delay of apps.out. 

For that I have tried early boot late weston usecase to implement this. But is this usecase feasible, if modified to show a logo screen at the beginning using the sysbios fw and later on show the output of apps.out ?

Does the control be passed to apps.out  to display the output and early usecase is not interfering here?? 

Looking forward to your valuable suggestions.

Regards,

Padmesh
