Setting Up Xilinx Utilities
The following instructions were written for Xubuntu 9.10 running on a VMware player virtual machine and may not work on other platforms or versions. If you would like to see additional coverage, please add it yourself or make a request on the wiki's wanted page.
Note that some utilities such as 'impact' are capable of using the libusb driver, while others such as 'xmd' must use the libusb-driver driver. libusb-0.1.4 is installed generally by default in *ubuntu distributions and should be available (but the udev magic still has to happen for the cable to work). In this install, we specify use of the libusb-driver by adding some lines in /opt/Xilinx/11.1/settings32.sh
Operating System
- Install Xubuntu virtual machine
- Update OS
- Reboot (to load latest kernel)
Re-Install VMware tools
sudo apt-get install build-essential linux-headers-`uname -r` psmisc
(Install VMWare tools through host menu)
Unzip tarball from /mnt/cdrom (or cdrom1) to local dir (such as ~/):
cd ~/vmware-tools-distrib sudo ./vmware-install.pl
Select all default options, allow the program to launch vmware-toolbox
Add the following to /etc/rc.local (then sudo chmod +x /etc/rc.local):
/usr/bin/vmware-user &
Add the following to /etc/fstab:
.host:/ /mnt/hgfs vmhgfs user,defaults 0 0
Reboot (Verify any shared folders are now mounted on /mnt/hgfs) (Verify vmware-user is running with: ps ax | grep vmware)
Supporting Libraries
Install libusb:
sudo apt-get install libusb-0.1-4
Install fxload:
sudo apt-get install fxload
Xilinx Tool Installation
Install Xilinx ISE Webpack (do not install cable drivers or XilinxUpdate), then run the following commands:
sudo sed /opt/Xilinx/11.1/ISE/bin/lin/xusbdfwu.rules -e 's:TEMPNODE:tempnode:g' > /etc/udev/rules.d/xusbdfwu.rules sudo cp /opt/Xilinx/11.1/ISE/bin/lin/xusb*.hex /usr/share/ sudo restart udev
- Note, for the first command you may receive a permissions error. Try the command
sudo suto get a root shell then run the same command sans 'sudo'
- Note, for the first command you may receive a permissions error. Try the command
- Plug in the Spartan 3E board. Apply power and attach the USB cable between the board and computer. If everything has been done successfully, a greed LED will illuminate next to the USB receptacle on the boad. If unsuccessful, the red LED will be dimly lit.
- Install the Xilinx EDK (SDK and Chipscope if required)
Installing libusb-driver
Install libusb-dev and git:
sudo apt-get install libusb-dev git-core
Download libusb-driver sources:
cd ~/
git clone git://git.zerfleddert.de/usb-driver
Compile and install libusb driver
cd usb-driver/
make
make lib32
sudo cp libusb-drive.so /usr/local/lib/
Create a script in /etc/profile.d/ with the following contents:
#!/bin/bash export PATH="$PATH/opt/Xilinx/EDK/bin/lin:/opt/Xilinx/11.1/EDK/gnu/microblaze/lin/bin/:/opt/Xilinx/11.1/SDK/bin/lin:/opt/Xilinx/11.1/ISE/bin/lin"
Make the script executable:
sudo chmod +x /etc/profile.d/xlilnx-settings.sh
Add the following lines to /opt/Xilinx/11.1/settings32.sh just after list=""
export XIL_IMPACT_USE_LIBUSB=0 export LD_PRELOAD=/usr/local/lib/libusb-driver.so
16) Prior to launching a Xilinx tool (such as xmd), you must type the following command:
source /opt/Xilinx/11.1/settings32.sh
- Note if you wish to create a launcher in the desktop environment, use the following format for the 'command' and it will automatically source the settings32.sh before launching the application:
/bin/bash -c 'source /opt/Xilinx/11.1/settings32.sh && ise'

Makefile Tricks
Automatic Download
This automatically downloads your program to the Spartan board after building. It assumes $(NAME).elf is the file you'd like to download. Note that you will probably miss warning messages regarding your code so you might want to first run make normally.
dl: $(NAME).elf echo 'dow $(NAME).elf' > xmd.ini echo 'run' >> xmd.ini xmd rm xmd.ini
When you're done, type exit to quit xmd.
Automatic Debug
debug: $(NAME).elf mb-gdb & xmd
When you're done, type exit on the command line to quit xmd.
