jpeyron Posted April 15, 2019 Share Posted April 15, 2019 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, Jon Link to comment Share on other sites More sharing options...
birca123 Posted April 18, 2019 Author Share Posted April 18, 2019 Hi @jpeyron, Sorry for the late response, I'm busy these days. The problem is that I've never used ILA modules before and it would take time for me to understand it. Can you check it real quick? The project files are available on the following link: https://www.dropbox.com/s/tjd21flsmxn650i/ZYNN_project.rar?dl=0 I appreciate your help, best regards.

jpeyron Posted April 22, 2019 Share Posted April 22, 2019 Hi @birca123, I reached out to one of my co-workers which happens to be currently having a similar issue with the Video Timing Controller on their project. We will be looking into this further but currently havent found a cause. We also would suggest to reach out to Xilinx about the Video Timing Controller hanging as well. best regards, Jon Link to comment Share on other sites More sharing options...
