So I followed the above design. But there is just no image coming on the monitor. So then I decided to only connect the dvi2rgb module and test if there is any signal coming out:
go pro -> HDMI -> Zybo -> pixelClk to on-board LED
Output the pixcelClk and connected it with the on-board LED and a counter(couting 75M so the flashing LED can be recognized by my eyes.)
I am not sure if there is something wrong with the way I configure the DDC part for dvi2rgb or if the code of dvi2rgb needs to be modified before using(Jieming mentioned in the above post).
Has anyone met similar problems?
Thank you for your time and any help or suggestions are really appreciated.
Question
Evocati
Hi everybody,
I am working on a Zybo project similar to what has been done here.
What I wanna do is simple:
go pro -> HDMI -> Zybo -> VGA -> monitor
So I use dvi2rgb and rgb2vga IPs just like what Marshall did in the above post
Marshall's schematic: https://forum.digilentinc.com/uploads/monthly_2015_05/zybo_passthrough.png.efb9f569b3fabcb8a452c95dc1ccc1e2.png

Still the LED doesn't flash.
