Hi,

We had studied the section3 of spracg3.pdf and tried on SDK2.10.0, but the display screen was abnormal.

This setting on SDK 2.10.0 have been verified?

or on SDK3.0.5, it have been verified?

Hi Yuki,

Can you please refer to source code referred in abstract of this app note.

Hi,

I haven't heard back from you, I'm assuming you were able to resolve your issue.
If not, just post a reply below (or create a new thread if the thread has locked due to time-out).

Yuki Chen,

Can you post a picture showing the abnormality?

- Subhajit 

The color is green,  but we still saw the shapes, like that two guys in the screen.

so HS/VS timing is correct, the Y/UV is abnormal.

We got the patch files form TI FAE, we applied the patches - 0005-visionsdk-enable-tdm-mode-in-usecase.patch and 0007-visionsdk-change-video-ouput-format-to-SYSTEM_DF_YUV.patch

Hi, 

Do you have any sugesstion?

It looks like your U and V values are 0. Can you share DSS  VOUT3 registers?

Hi, 

Because of some reasons, we postpone  the "YUV422 Progressive BT.601 Displayout" verification 1 month later.

You can set this subject to other stutas, I will ask on E2E again when we retart this verification.

Thanks!
