Hello. I hope I will get an answer, because I am quite stuck...
I have been trying to get HDMI working with bare metal, and so far no luck...
My project is a custom graphic controller, so it is not just sticking a AXI Stream to a module, reading DDR and writing to the ADV.
(I have taken various route (and many hours) as described in the following link and in google if you type "zedboard hdmi adv7511", so please do not send something I already googled a thousand time.)
I am running 2016.4 version of Vivado.
1/ I did not want to go with custom IP from xilinx : I am writing my own pixel pipeline and just need the part accessing the ADV. So I need to control what is going on... Moreover, I would like to have my design as portable as possible.
So I did not use this solution from ZedBoard site : ZedBoard HDMI VIPP, Vivado 2014.1
2/ I used GIT, directly taking samples from ADV directly running TCL script, no luck. Failed miserably... Whatever the reason.
3/ I used from the Zedboard site : HDMI Bare Metal Reference Design Using ADV7511 and ADI IP
Did not work in 2016.4, so I downloaded and installed 2013.4 (which refused for whatever reason to launch the GUI after install) but I could at least run the tcl command, so I got the thing to compile.
Then imported into my latest Vivado version, and bam... lots of unsolvable error due to IP design change.
I would not mind updating the thing if at least I had something workable step by step and be sure I do not break anything, but debugging something that I did not even design...
4/ Directly went with the only project that mostly ran RIGHT AWAY (we must conceal simplicity is the mother of all dev)
http://hamsterworks.co.nz/mediawiki/index.php/Zedboard_HDMI_v2
2 VHDL files + 1 UCF (that I had to convert of course to XDC because there is no import function in Xilinx tools)
But unluckily, I was not able to have a valid HDMI output (seemed like the DDR data pumping into ADV has a timing issue, I do not get black, red, etc... vertical color stripe but alternating colors every pixel (RED, YELLOW, RED YELLOW))
That person is using ISE, and I have seen that ISE seems to generate more timing efficient design, I was wondering if my visual problem could be a poort timing issue but whatever...
It is driving me a bit crazy, I have spent probably nearly 30 to 40 hours on that stuff...
Is there any plan to have an upgraded project of the 2013.4 project to newer version, or a minimalist thing that just work ?
(even without memory to pixel path, just take the X & Y counter to generate RGB values with a XOR or something ).

Romain.
