JTAG chain detection failed in xilinx platform cable USB

Jump to solution

Hello,

 

  I was using xilinx platform cable USB 2 previously for many days in my windows 7 ultimate system. It was working properly. Now I switched to a desktop with windows 7 professional. Now when I plug in the debug cable in chipscope as I try to connect i get:

ERROR:No devices detected while scanning the JTAG chain
ERROR: Failed detecting JTAG device chain
ERROR: Opened Xilinx Platform USB Cable but failed to detect JTAG Chain.

In impact as I try to initialize chain I get:

A problem may exist in the hardware configuration. check that cable, scan chain and power connections are intact ,that specified scan chain configuration matches actual harware and that power supply is adequate and delivering correct voltage.

 

I checked in device drivers that Jungo driver installed properly. Also I tried reinstalling from ug344_windows.zip. But error persist.  I think this relates to change in operating system. There is some missing dll or something for chipscope in this system. Suggest me some remedy.

 

With regards

Shalini

can you uninstall and reinstall the cable driver by following the commands

 

  1. In a command prompt browse to your "C:\Xilinx\<version>\ISE_DS\ISE\bin\nt64" directory on 64-bit installs or "C:\Xilinx\<version>\ISE_DS\ISE\bin\nt" on 32-bit installs.
     
  2. To uninstall type the command:
    wdreg -compat -inf %cd%\windrvr6.inf uninstall
     
  3. To reinstall type the command:
    wdreg -compat -inf %cd%\windrvr6.inf install
