Hello Harpreet,
Did you manage to figure out a solution for your issue?
I've been trying to do what you describe using the adv7341 eval board, and while I can get the chip to pass through the h/vsyncs, I just can't get video on DAC 4/5/6.
I'd love to hear if you found a way to get working pass through - essentially treating the adv7341 as a generic DAC and if you'd be willing to share how?
I have video coming from an upstream ADV7403, 30 bit SDR 4:4:4 RGB with sep syncs. I've even been tying off the blank signal since it's floating on the eval board by default (tried chaining from adv7403, tying high / low and inverting polarity in the adv7341... no luck)
regards
Ian
