Xilinx Multilink Connection not working

Hi

I have a Xilinx Multilink cable that I would like to use to communicate with a Xilinx VirtexII that is hosted on a PCI Mezzanine board. I connected the PCI Mezzanine board with the cable following the guidelines in the User Guide for Xilinx Impact. In other words, I connected the GND, VCC, TDO, TDI, TCK and TMS. There is a green led on the Multilink cable, which is not flashing although power supply should be provided by the PCI card. The PCI card itself is working, so I dont know if I have to switch into a special kind of mode so that the JTAG interface is enabled? Does anyone have any experience with that? Or is the Multilink cable probably broken?

Thanks for any assistance! Philipp

Alright, at least the multilinx cable is working, so the LED flashes. I connected the GND, VCC, TDO, TDI, TCK and TMS. Still I cant get a connection over the serial port which is quite weird. I used automatic detection but I get the following error blog from Impact. Is there an issue with the drivers? In addition, I use two DB25 adapters in order to connect the cable to the board. Shouldnt be an issue either, is that correct?

Philipp, I have some suggestions:

1- Look around for a patch of multilinx on Xilinx website. Although it solved my problem but many of the usb devices (including my mouse) stopped functioning after applying this patch.

2- Try changing the PC-connectivity of multilinx (from USB to serial).

Hope this helps.
