We use 320x240 and 640x480 YUV sensors for connecting DM36x chip based on Appro reference design (the 320x240 is resized to 640x480 before sending to display process). The analog TV output works but we always saw a few lines of white lines either at the bottom or top (depending on NTSC or PAL). Also, the start pixel for frame does not appear to be the leftmost pixel but middle pixel (It is hard to see).
What register setting could cause this problem ? I checked the HSTART, VSTART, VSTART, VVALID and they are all 0. I tried to disable blank in CVBS register. But that just adding a vertical white line on the right.
Does this have anything to do with analog TV used ?
Thanks.
