Hi,

I'm currently trying to do the tutorial for "FMC-IMAGEON Building a Video Design from Scratch Tutorial" (version 1.3 from january 3. 2013) with ISE Design Suite 14.7 using a ZedBoard and the FMC-IMAGEON HDMI I/O-Module. Everything seems to be on schedule, and part one (implementing the pass-through) builds and runs, except for that the screen stays black. The information Putty shows me is as following:



"Press ENTER to re-start ...
Waiting for ADV7611 to locked on incoming video ...
        ADV7611 Video Input LOCKED
ADV7611 Video Input Information
        Video Input      = HDMI, Progressive
        Color Depth      = 8 bits per channel
        HSYNC Timing     = hav=1920, hfp=88, hsw=44(hsp=1), hbp=148
        VSYNC Timing     = vav=1080, vfp=04, vsw=05(vsp=1), vbp=036
        Video Dimensions = 1920 x 1080
ADV7511 Video Output Information
        Video Output     = DVI, Progressive
        Color Depth      = 8 bits per channel
        HSYNC Timing     = hav=1920, hfp=88, hsw=44(hsp=1), hbp=148
        VSYNC Timing     = vav=1080, vfp=04, vsw=05(vsp=1), vbp=036
        Video Dimensions = 1920 x 1080
HDMI Output Initialization ...

Done"

I should mention that I'm using a GoPro Hero 3 Black video camera that is set to stream 1080p60 to my HP LP2475w monitor using HDMI cables. No matter if i connect to the monitor using DVI, the message in the terminal window looks the same, and the screen stays black. I've also tied to use 720p60, but same message, black screen. I've searched through your forums and others forums, without any results. I've read it can have with the HDCP to do, but I don't think the GoPro has HDCP encryption/handshakes.

I've tried to do the tutorial in Vivado as well, but that didn't complete (I used vivado 2014.2). => If a solution is easier to achieve here, please let me know.

In other words; how can I get the HDMI-passthrough to work properly?

    Ingebrigt,

    The HDMI passthrough example code would indicate "HDCP Encrypted", if encryption was detected at the HDMI input (ADV7611), so I would agree that your video source is probably not encrypted.

    We can try two things:

    - I can send you a working solution to a Vivado project, for you to try with your setup

    - I can try your 14.7 project on my side

    Let me know what you want to try.

    Regards,

    Mario.

    I'm currently re-installing Vivado to 2013.3, which is the version used in the example. If you could send me a working project for 2013.3, I'll try to make it run on my computer.

    I guess that is a preferable solution instead of trying to make my ISE 14.7 project work?

    I've installed Vivado 2013.3 and run the respective HDMI-pass-through the, same result. But I've also noticed that the GoPro support says "Regarding other features of the HDMI output of our camera here it goes a

    Can this problem be frequency related?

    Hi albertabeef,

    I am also to bring-up the FMC-IMAGEON Avnet eval board along with Zed board. I have to take a video IN through HDMI Rx And internally have to do Mixing with an image. Then on TX HDMI port have to display the Image along with the Video should run in the background of the Image. Please Guide and share the vivado project with me also. So I can take a reference design and can proceed further.
