prog from Impact OK, from SDK failed.

Hello,

 

I have a custom board with 3 devices in the chain : Sysace, Virtex5 and Virtex6.

 

Using Impact I am able to program each one of the FPGAs, but, from the SDK I cannot program any of my FPGAs (with little EDK systems created using the wizard).

 

I have already modified the download.cmd file. In the case of the V6, it is the component # 3 in the JTAG chain (I saw it in Impact, look attached figure).

 

 

So my download.cmd  file is :

setMode -bscan
setCable -p auto
identify
assignfile -p 3 -file implementation/download.bit
program -p 3
quit

 

 

Error message:

"FPGA configuration encountered errors.
Program FPGA failed
   ERROR: Connection to Board Failed

Failed to Open JTAG Cable
    Cable target is not connected to the host
"

 

Am I missing something?

 

 

Regards,
