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 su to get a root shell then run the same command sans 'sudo'
  • 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.
