Nexys Video No Hardware Target Exists


I am trying to operate the Nexys Video development board using the vivado hardware manager on a windows 8 system. However I keep getting  No hardware targets exist on the server error. Steps i have taken to remedy the situation include:

  • Re-installed Vivado with included cable drivers
  • Tried different versions of vivado
  • Tried on a different PC
  • Formatted PC and installed vivado
  • Updated FTDI drivers
  • Tried 3 different (new) USB cables
  • Installed cable drivers manually

The programming jumper is in the right position (jtag), the USB cable is plugged into the correct (prog) port and the board is powered. Can anyone suggest anything else I might try to fix the issue?

For Nexys Video the USB Serial Converters are not supposed to show up as COM ports.
Under USB Serial Converter ( A and B ) properties uncheck the Load VCP option and reconnect the device.

Please check if the device is recognized by Adept Application. This is installed by Adept System: https://reference.digilentinc.com/digilent_adept_2

Which USB driver version do you have installed ?

Which Vivado version are you using ?

I am using USB driver version:

I am Working with vivado 2015.4.  I have also tried 2015.1 and 2016.1. 

The board does not show in adept. It shows no devices connected. 

Unchecking vcp made the com ports disappear. But vivado still gives the error and the board is still not seen in adept.
