My problem is that adv7181 have no color output but only black and white
I gave PAL video to adv7181,and the av code of bt656 has correct Y component,but the CbCr component is always 0x80,so I got a picture without color.
I have configed the register with reference provided by ADI like this :
"AUTODETECT CVBS IN NTSC/PAL/SECAM 8 bit 4:2:2 ENCODER"
How can I get the correct CbCr component ?
