i.mx6 480p CSI0 dark colors

[allanmatthew]

Hello-

I'm running an i.mx6 solo with an AD ADV7610 HDMI decoder connected via a 16-bit bt.1120 connection to CSI0.  In 720p and 1080p modes the video looks great.  But, when I switch to 480p (640x480p60 in this case) I get strange dark color bands in the video (see attached).

I believe the ADV7610 is still outputting 16-bit YCrCb data, as the colors look OK except for the dark bands.

Any ideas as to whats causing this?

Thanks,

-Allan

when you use 480P, did you change anything? when you bootup ,any error log file can be checked?

Hi Guanquiong-

It was actually an incorrect setting on the ADV7610.  In case anyone else runs into this problem, I was running in HDMI-COMP mode instead of HDMI-GR, changing to HDMI-GR fixed the issue.
