HDMI's output lines seem to be rotated.

Hi,

I'm using DVR RDK (02.00.00.24) with DM8168.
It outputs graphics through HDMI.
But its 1st (top) line data seems to be shown on the 2nd line, 2nd line data is on the 3rd line, ..., and 1080th (bottom) line data seems on the 1st line. That is to say the line data seems to be rotated by 1 line.
How (Where) should I make an arrangement about this issue?

I'd appreciate if someone give me an info, tips, or any URL of the similar Q&A.

Regards

Takahiro Yoshizumi

    Pls migrate to DVR RDK 4.0 and check the behavior. There have been several fixes since the DVR RDK 2.x release in HDVPSS drivers and the issue you are seeing may already be fixed.

    Hi Badri,

    Thank you for the reply.

    I would like to try 4.0, but I might not have enough time to do that.

    When I change source code as follows, this issue seems to be solved:

     

    /dvr_rdk/dvrapp/app/src/lib_dvr_app.c  (around line 4630)

    - regp.scalaren = TI81XXFB_FEATURE_ENABLE;

    + regp.scalaren = TI81XXFB_FEATURE_DISABLE;

     

    But I don't have confidence if this change is collect.

    Could someone give me further advise?

     

    Regards,
