I have written it all up on my own site. I managed to get it. I have appended a little onto your howto, and of course referenced your work

George,

I haven’t upgraded to Gloria yet. However, I vaguely remember an error message something like this and I think the way I got round it was to shut my machine down, plug the cable into a windows machine and download a bitstream to a board then connect the cable backup to the linux machine and power up again. Everything seemed to work fine after that.

If you discover any other solutions to this problem drop a comment here, so that others can benefit from your debugging

It looks like Xilinx have changed the installation path in newer release’s of ISE. So, I’ve added you comment here for future reference.

I too am having the same problem.

Spartan-3E Starter Board
Xilinx ISE WebPack 11.1
Linux Mint 7 Gloria – Main Edition (i686/32bit)

I got everything installed okay, and with bo problems noticeable. Apart from that noted above, that is.

However, I go to iMPACT and try to do anything, I get

WARNING:iMPACT:923 – Can not find cable, check cable setup !

I have tried under cable setup, to select the USB one, and get the following:

PROGRESS_START – Starting Operation.
Reusing A0035551 key.
Reusing 24035551 key.
OS platform = i686.
Connecting to cable (Usb Port – USB21).
Checking cable driver.
File version of /opt/Xilinx/11.1/ISE/bin/lin/xusbdfwu.hex = 1030.
File version of /usr/share/xusbdfwu.hex = 1030.
Using libusb.
Cable connection failed.
PROGRESS_END – End Operation.
Elapsed time = 0 sec.
WARNING:iMPACT – The cable selected is not avaliable, please select a different one.

Any help would be greatly appreciated. Kind Regards

The line

export LD_PRELOAD=/opt/xilinx/usb-driver/libusb-driver.so

needs to be changed to

export LD_PRELOAD=/opt/Xilinx/usb-driver/libusb-driver.so
(such that Xilinx has a capital)

Else I get problems about it not being able to preload the driver and thus it gets ignored.

Hi Matt, It sounds like your still missing the JTAG programmer, you need to connect the Red device in this picture to the USB cable (printer connection side) and then connect the JTAG programmer to your development board.

I still get:

WARNING:iMPACT:923 – Can not find cable, check cable setup !

when I run iMPACT and try to do anything with the cable. My cable is USB to USB (one end is the standard USB terminator, the other end is like the one printers use). Does that count as JTAG? Is JTAG just the protocol?

Any help?

Hi,

This error appears to only happen with Fedora 8. The fix for this appears to be, change uint32_t to u_int32_t at line 253 in usb-driver.h and change uint64_t to u_int64_t at line 254 in usb-driver.h.

I’m having problems compiling usb-driver on fc8
In file included from xpcu.c:9:
usb-driver.h:253: error: expected specifier-qualifier-list before ‘uint32_t’
make: *** [libusb-driver.so] Error 1

libusb-driver is installed. Any ideas? I’m using the git version of usb-driver.
