AM5728: DSS writeback examples to control VID1/2/3 pipeline

Part Number: AM5728


Dear Champs,

My customer is using AM5728 and Linux PSDK v3.1.

They want to test write back of DSS, and they found the example for it as below.

https://github.com/tomba/kmsxx/blob/wb/tests/wbtest.cpp

But, only with this file, it is hard for them to find method to control DSS vid1/2/3 pipeline to display it.

Could you please help on this?

Thanks and Best Regards,

SI.

    Hi SI,

    What's meant by only this file? Other relevant files are under wb/test folder of that git repo.

    What's the use case? This is the only example existing today on display write back. Look for m2m_xx() APIs for writeback specific protocols. Other feature of DSS like scaling and overlaying is demonstrated using DRM APIs in dual-camera-demo application that is part of PSDK.

    Le me know specific questions or issues being faced using wb/test application

    Regards,
    Manisha
