  1. I'm trying to get the Pmod Color module for the Zynq z7-10 to work but it doesn't appear to be on. I was following along the instructions from these sites: https://reference.digilentinc.com/learn/programmable-logic/tutorials/pmod-ips/start https://projects.digilentinc.com/arthur-brown/displaying-color-readings-with-the-pmod-color-and-python-ebd794 and I have it connect to the device as such on the board's JA port: Following along with the first link, I skipped the steps where a clock and interrupt were added as the data sheet shows that the Pmod Color IP does not require these. I have included my schematic below. I see that the module has an LED pin (LD1) but it doesn't appear to be on when connected to my powered device. In the SDK, I added a debug 'else' statement to the main() portion of the code to see if the Pmod is receiving data. After running the code on the board, the else statement is the only statement being executed. What could be the issue that my module is not turning on? I took a voltmeter reading, and the Vcc and GND pins are getting 3.3V. Following the instructions of the first link, I noticed they never included a constraints file. Could this be the issue? zynq_ps_main_c.c
  2. I'm following along with the instruction provided on the GitHub (https://github.com/Digilent/Zybo-Z7-10-HDMI/blob/master/README.md) to test the functionality of the Zybo board's HDMI ports. I followed the instruction to the T but cannot seem to get a signal to pass through. At first, I connected my cable box to the HDMI Rx and then I switched to my laptop. In both instances, not only did my TV monitor not detect a signal, but the output on the sdk terminal was that the HDMI-in was unplugged (see first attached photo). The HDP / LD9 LED near the HDMI port turns on, telling me it is detecting a signal. Using the Zybo-Z7 reference manual, I deduced that it might be due to an issue with resolution, but if I try to change the resolution, I get 'stuck' in that menu (see second attached photo) and have to restart the processes by clicking run-as -> Launch on Hardware. I also notice the clock frequency is set to 0, but I'm not exactly sure what could be the issue. I have also attached the block design and xdc file as I'm assuming the issue could be there since the pixel clock isn't running. design_1.pdf Zybo-Z7-Master.xdc
