Uzaif Posted April 12, 2017 Share Posted April 12, 2017 Hi, I am trying to develop a simple project for HDMI to RGB. I am using dvi2rgb core and clock_wizard for generating a reference clock for it. I supplied 200MHz to dvi2rgb. I tried both MMCM and PLL modes in clock_wizard configuration. But when I dump the bitstream on Zybo Vivado shows the following warnings and my design doesn't work. WARNING: [Labtools 27-3123] The debug hub core was not detected at User Scan Chain 1 or 3. Resolution:1. Make sure the clock connected to the debug hub (dbg_hub) core is a free running clock and is active OR2. Manually launch hw_server with -e "set xsdb-user-bscan <C_USER_SCAN_CHAIN scan_chain_number>" to detect the debug hub at User Scan Chain of 2 or 4. To determine the user scan chain setting, open the implemented design and use: get_property C_USER_SCAN_CHAIN [get_debug_cores dbg_hub]. Attached are my block diagram which I'm implementing, and my constraints file. Please help me. I have read a lot of posts on this project but couldn't find any solution that can work for me. If you want my project file I can attach it as well. Thanks ZYBO_Master.xdc Link to comment Share on other sites More sharing options...
