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 -bscansetCable -p autoidentifyassignfile -p 3 -file implementation/download.bitprogram -p 3quit
"FPGA configuration encountered errors.Program FPGA failed ERROR: Connection to Board FailedFailed to Open JTAG Cable Cable target is not connected to the host"
Am I missing something?
