Thanks for the reply. it would be really good if you could try the script i sent on your evaluation board with the set of resolutions that are still failing for me. It would give an insight on where exactly the problem is.
Based on your experiments with the above failing resolutions if you could recommend any change in the script we could give that a try. Our custom board is more or less same as your evaluation board.
Regarding CRC we just capture the video frame output from ADV7619 and have a custom algorithm to calculate CRC for it. I don't suspect any issues with CRC here. I think we are just missing some correct programming for ADV7619 for these resolutions and any help would be appreciated.
