Hello,
My application freezes after I run the self-test for a video timing controller. What is the cause of the problem?
The used Block design is shown below and project files are available on the following link: https://www.dropbox.com/s/tjd21flsmxn650i/ZYNN_project.rar?dl=0
Best regards,
Toni

Hi @toni_birka ,
Do you have the HDMI connected? I believe you need to have an active HDMI clock else the VTC will return a slave error on the AXI4-Lite interface:
So any access to the IP will report an error. This is probably what you are experiencing

Hello,
sorry for the late response. I’m pretty sure that it has active clock, because i have connected GoPro camera on HDMI input.
Best regards,

Hi @toni_birka ,
You migth want to make sure the clock is here. I would recommend to do some logic to toggle a LED to make sure you have the clock.

Hi @toni_birka ,
Check the xdc file or user guide for the zybo to find a led you can use. And the clock is the one connected to the clk input of the vtc

Hi @florentw,
I connected the LED to the Pixel clock which is input to the vtc, and edited the .xdc file, but when I tested it LED didn't work. I use GoPro camera as the HDMI source, and it's working when I connect it to the TV via HDMI. What should I do to fix it?
Best regards,
Toni

Hi @toni_birka ,
Well you need to have the gopro working...
What could happen is that the Gopro does not support DVI over HDMI. This might be why you are not getting the clock.
So either change your source or use a HDMI RX solution (true HDMI not DVI over HDMI).
