Vivado Hardware manager does not detect any devices on the UltraZed-EG SOM board

eran99

I'm connected to the Avnet UltraZed-EG SOM board using DLC10 USB-JTAG

adopter.
when I click on open-target and then auto-connect, the DLC10 is detected, and the UltraZed-EG is detected - I know that since it says:

Xilinx_tcf/Xilinx/00001877ae8201(0) "open", but if I unplug the jtag connector is says "closed".

However, it says Device Count 0 under properties, and I'm getting a message " No devices detected on target"

 

I set all 4 DIP switches to ON, which is 0000 for JTAG boot mode.

 

Is there any other setting or jumpers I need to deal with on the UltraZed board, or perhaps it's a driver issue?

    I found that there’s a problem with a reset signal on the JTAG connector (Pin 14) that resets the FPGA once I connect the JTAG cable so that’s definitely a problem that would cause the FPGA to not be found. Hopefully that's the only issue.

    Given that, the question now comes to: Is there away to configure the DLC10 to block/disconnect pin14?
