The ramp picture problem

[deshenggao]

Dear All:

    We  use the i.MX6dual with the MIPI input function.

And we found that when we setting the MIPI as  RGB24  format.

We  will see that the test pattern RAMP picture is not smooth, you can see the green stripe.

(Please see the attach file ramp(RGB24).png),

if  we changed the MIPI to YUV422 format.

You will not see the problem (Please see the attach file ramp(YUV422).png), 

Which part or which  register should I check?

Thank you !

What Camera are you using?   I think the problem it is not in the  MIPI interface, since when you change the format the image gets clear,  so  what  version it is required by your camera?

Hi Jamesbone:

    I do not use the camera. I use the signal generator . I also  use the ADV7480 which can  output  MIPI  signal supported  both YUV422  and RGB888 to do the test. and only  RGB888 format  have this issue,  so I guess that some

registers or place should be noticed in the i.MX6.

Please give me some advices .

Thank you!
