Xilinx Platform Cable Usb Ii
I just started working with FPGAs/CPLDs. Coding and simulation went well and now I wish to program a device. So, I bought the programmer and then followed the guide for device configuration. For my Win7 x64 and ISE 14.7 I downloaded a dirver stated on p.15, Step 5.2. After extracting the files and running the installxusb.bat as administrator, I got the following message from the console window 'cannot run x86 build of this utility on x64 platform':The folder of the driver contains both nt and nt64 folders, so I assume that the driver for x64 is present. Any one has an idea of what's the problem with the driver installation?
Xilinx Dlc9g Drivers
When fighting this problem so much, I tried a lot of different things, icluding installing/uninstalling driver via console cmd.exe, I even reinstalled the ISE pack (which installs driver cabels with it) - but with no success. Someone mentioned to try connecting the device to the USB port that is actually located on the motherboard, so I did it and the device is finally recognized, but no status light is let on the device. Here's the screenshot of my device matager:But now I have another problem - when I try to selelect this device in IMPACT, no device is found:At the same time, the console report shows that the driver is present (below), and the device manager says that device is connected (above):Any ideas of what's the problem there?
Hi,1) Go to the Xilinx Command prompt (which has the environment variables set already). Check the screenshot below on where to find the command prompt2) Go to the folder in this command prompt cd C:/Xilinx/14.7/ISEDS/ISE/bin/nt64 on your computer and search for 'wdreg' as shown in the screenshot below. I am sure you can find it in this driectory.3) Now give the below commands one after another. The first one uninstalls the drivers and the 2nd one re installs them.wdreg -inf uninstall.inf -silent -log uninstall.log uninstallwdreg -inf xusbdrvr.inf -log installxusb.log installHope this helps. Guys,I greatly appreciate all your input in trying to find out what was the problem with the device. I actually gave up and started packing the device for return and noticed that USB cable and the DLC9G Programmer came in one box, but different bags. I thought, what if amazon made up this order themselves and used a crappy usb cable?
Indeed, after getting my own usb cable, the red light came on right away, but the green one did not come until I provided reference voltage. Thank you, and good luck. Hope this experience will save lots of time to someone else. Keep this option in mind. Hi I've had the exact same problem,I think I fixed this problem for my computer. In the Datasheet DS300.pdf there is a small blurb that gave me the clue.
Under Pg 2, under the note it states'Note: The DLC9G and legacy DLC9LP cable models draw lessthan 100 mA from the host USB port. The legacy DLC9 cablemodel requires 230 mA to operate in USB 2.0 Hi-Speed mode or150 mA to operate in USB 2.0/1.1 full-speed mode. Some olderroot hubs or external bus-powered hubs might restrict devices to100 mA. The legacy DLC9 cable model does not enumerate onhubs with the 100 mA restriction.' It turns out I was plugging in the programmer cable into the front of my computer which has a USB port that does not supply enough current to fully power the DLC9G, the LED was dim when plugged in, windows recognized it but iMPACT did not. Upon pluggin the programmer to the usb port at the back of the computer, the programmer's LED was much brighter and iMPACT was able to detect it. I'm guessing my computer has higher current USB ports in the back then they do the front.
