I am using ADV7842 to receive video over CVBS, S-video and VGA interfaces. I also have EVAL-ADV7842-7511 board with me.
I have tried displaying 1080p60 VGA video on evaluation board and it is working properly. When i am trying the same in my board (1080p60 video over VGA and using the same script), ADV7842 is giving out 1080p60 black video.
Standard detection and identification (STDI) is working properly (block length, line count and field length matches with the standard) and ADV7842 is giving out 1080p60 blue screen (free run) video when the VGA cable is removed.
Following is the summary of my setup
1) input video is 1080p60 RGB over VGA interface
2) using AUTOMATIC INPUT MUXING
3) Output mode is YCbCr 4:2:2 SDR embedded sync (OP_FORMAT_SEL[7:0] = 0x81)
Can anybody help me resolve this issue?
