Hi all,

Is it possible to configure the display pipeline from the low level ? Do you have sample application to test the same ?

Hi Gokul,

can you give some more details - which SDK you use and what you want to achieve?

Also can you check if any of the following is what you look for:

Hi Yordan,

Currenlty We are using 3.01 kernel from TI and We will migrate to glsdk/infoadas-kernel:infoadas-on-psdkla3.03 kernel.
(git.ti.com/.../)

Consider one pipeline vid1 which shows splash screen using drm and other pipeline GFX which shows Graphics HMI using weston. On bootup We like to show splash screen using vid1 pipeline and then switch to HMI-GFX pipeline.

Do you have sample application to achieve the same ?

Hi Gokul,

I have forwarded your question to a DSS expert for comment.

Gokul,

We do not have a sample application to do the same.

DRM only allows one display master at a time. As a result, you will need to close the DRM splash screen application before starting weston. This can lead to a brief moment when the screen is blank.

Venkat
