you're right, screen is rolling to upside. maybe about 2 pixels every frame

Hello,hyunho,

     I judge the issue looks like different CVBS standard. For example:

(1)NTSC

if CVBS camera is NTSC , TVP5158 should be set NTSC standard.

(2)PAL

if CVBS camera is PAL, TVP5158 should be set PAL standard.

So, I feel standard setting in TVP5158 is differenct from it's CVBS signal(camera) input.

check it and try !

Regards,

Weidong

TVP5158 setting was fine

CSI input size was 720 x 525 in base source(IMX6 original code)

I changed that 720 x 525 to 720 x 488 and EAV/SAV code exchange. so, it work fine(no image rolling)

thanks to your opinion.
