Ubuntu on Zedboard, no video display

Ubuntu on Zedboard, no video display

I have gone through all the instructions in "Tutorial: Ubuntu on the Zynq-7000 SoC Featuring the Avnet ZedBoard" (May 2013, Version 02).

The board will boot but there is no video. The boot log, shown below, shows an error writing to the ADV7511.

Any ideas on what's going wrong?

RE: Ubuntu on Zedboard, no video display

Hi rdbirt,

There is a test that you can run to isolate whether this is a hardware problem or perhaps a PL build problem.

The out of box demo initializes the ADV7511 device and should display two instances of the Tux logo on your 1080P HDMI panel.

If you no longer have that out of box image available on your end, it can be downloaded from the Digilent site. A link can be found on this project page:

Once you have that image installed to an AD card, refer to the Getting Started Guide for instructions on setting up the panel.

If the out of box Linux image works to display the Tux logos, there could be something wrong in your PL implementation when following the "Tutorial: Ubuntu on the Zynq-7000 SoC Featuring the Avnet ZedBoard" document. If the logos do not appear when using the out of box Linux image and you still see similar ADV7511 initialization errors in the kernel debug output, you could have a hardware issue on your ZedBoard.



Hi Kevin,

Hi Kevin,

Thank you for the reply. I do see the Tux logo from the HDMI. I also can see a scrolling Digilent banner on a background of coloured bars from the RGB connector. Seems the hardware is fine.

WRT the PL image, is there a way to test if what I generated is correct?


Same problem here

I got the same problem here.

I follow all the step of Labs and there is no error message, I don't know why the HDMI output not working.

Same problem with HDMI


I also got the same problem.The problem not in the board because I changed the board and still got the same problem (no output on the screen ).


Same problem with HDMI

I followed the FMCOMMS1 tutorial and can boot but also do not have HDMI output (similar errors noted above) has anyone figured this out?
