HDMI display controler

Former Member

Hi everybody,

I'm lost with vivado versions, i have done the tutto of " diplay controler HDMI" on version 2014.1 i have got my color bars in my monitor via HDMI till now all it's good.
But when i got copy this project to another machine version 2015.3, i have upgrade all ips after synthetising, implementation and bitstream.

I have run my software in SDK as i have done in version 2014.1. But the prob i cannot see the color bars.
My monitor does'nt recongnize the HDMI :(.

My question is : does someone know the reason why i cannot see the same results ??
Do I need to change something to make my porject 2015.3 works as 2014.1 ?.

Thank your for your feedbacks.

Kind regards

    Hi there,

    Is it this design:
    ZedBoard HDMI VIPP, Vivado 2014.1

    from this page:
    http://zedboard.org/support/design/1521/11

    that you are working with?  If so, you jumped a LOT of versions.  I would suggest you stay with 2014.1 until you learn more about the design.  There are some changes that occured with the built in Video IP between 2014 and 2015.  For instance there are a few clocks that were changed around or removed.

    Things like that could be plaguing your design.  If you really need to move forward with 2015, you will need to investigate which IPs are causing your issues.  Again, I would start by investigating the clocks as that is one thing that I am aware was changed between 2014 and 2015 versions of Vivado.
