impact virtex 2 not detecting
Hello guys,
I have a Avnet Virtex-II Pro Eval Board, do I have to use EDK to program the chip?
I ask this question now because I have EDK and ISE 8.1 but I only have a Multi-Linx cable which is no longer supported by Xilinx. I have to go back to use version 7.1 but I dont have EDK 7.1.....
Anyway, I tried to test the board by first powering the board with default jumper settings. Everything seems ok; I see the LED array flashing. Then I changed the jumper settings to JTAG mode, fired up iMPACT to see if I could detect the device in Boundary Scan Mode and got a problem.....When iMPACT was identifying the scan chain it kept on adding UNKNOWN devices. It seems the chain is infinite and I had to force the program to stop......I called Avnet about the problem and subsequently got a replacement board but I still have the same problem....(I am sure I got a different board bacause the chip is faster than the previous one)
So I want to know if the board is actually defective, or it just doesnt work with iMPACT (which I think is pretty weird if it is really so). Any owner of the same board can help me with this issue?
Thanks,
