Running VTC self test freezes on ZYBO



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.

Best regards,

Hi @birca123,

The AXI bus may be waiting for the peripheral to respond (by acknowledging the write) and it isn't.

This can be caused by a variety of things, but having the addresses wrong would be one to check. Can you add an ILA module and see what bus transactions are taking place?

Here  is a xilinx forum thread about possible timing issues from the video timing controller.

best regards,
