iMpact - Initialize chain Vs IDCODE fail

Hi,

I am using Avnet's PCIe SP6 board.

I was able to confugure FPGA using iMpact and Xilinx's USB cable.

 

There's some prob now:  

when iMpact is run and asked to do "initialize chain" it detects / displays correct FPGA in GUI.

After that, if "get IDCODE" is done, returns wrong IDCODE and gives INFO:585 msg. Which recommends to check voltages, chain etc. 

 

How at first-place (when impact being run from scratch)  impact can detect device? -- when IDCODE being returned is wrong for whatever reason. 

 

[I have checked supply voltages they are corect 3.3, 2.5, 1.2 .... ]  

 

thx,

Manish
