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

Re: Xilinx Multilink Connection not working
 
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.
