  1. Hi @jpeyron I also faced the same problem. When I run this project without Edge Detect ip, i get the same Hdmi out as input on monitor. But when I use edge detect ip, after uploading bit file on zybo z7-20 board, the Hdmi Rx light glows but output doesn't appears. Block design is attached design_1.pdf
  2. Hope you all are fine, I downloaded Digilent/Zybo-Z7-20-HDMI from I have upgraded the ip's, it was displaying output on monitor. Then I have created the ip of sobel edge detection and added the ip in block diagram. After solving some clocking issues, bitstream has been generated. After launching to sdk, when I Launch on Hardware (System Debugger), output doesn't display. Below is block diagram, please guide me
