    Problem of using PL part to access the GPIO

    pmuproject

      Hi,

      I'm using Ultra96 with Ultrascale+ core. I followed this video (https://www.youtube.com/watch?v=NzWcRGjhfF8) to implement an example of using the PL part to access GPIO pin. But the codes on my device is not working. I used the oscillocope to check the voltage of the GPIO pin and the voltage is 0V. Below are the pictures of my system.

      I'm using Vivado 2018.2.1. I connected my Ultra96 to my PC through JTAG. Then I used the "Program Device" button under hardware manager to program my Ultra96 after the bit stream generating. When I clicked "Program Device" button the picture below shows "there are nod debug cores". Is this meaning I can't use this way to program my device? Could anyone help me to check what is going wrong? Thanks!
