• See FPGARelated.com posts, especially the one by Jan Pech
  • Note formatting issues in this post. Get rid of all 3D instances; fix wrapped lines to be single lines; be sure to introduce spaces where they were deleted by the line wrap
  • The resulting xusbdfwu.rules should look like:

    Code Block

    # version 0003 ATTR{idVendor}=="03fd", ATTR{idProduct}=="0008", MODE="666" SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="03fd", ATTR{idProduct}=="0007", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusbdfwu.hex -D $tempnode" SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="03fd", ATTR{idProduct}=="0009", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusb_xup.hex -D $tempnode" SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="03fd", ATTR{idProduct}=="000d", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusb_emb.hex -D $tempnode" SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="03fd", ATTR{idProduct}=="000f", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusb_xlp.hex -D $tempnode" SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="03fd", ATTR{idProduct}=="0013", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusb_xp2.hex -D $tempnode" SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="03fd", ATTR{idProduct}=="0015", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusb_xse.hex -D $tempnode"

• Make sure dongles are disconnected from USB and applications attempting to interact with them are not running
• Become root (sudo -m)
• Need to have libusb, libusb1, fxload installed (see above)

  Code Block
  yum install libusb libusb1 fxload

• Write permission is needed to run the installation script, so

  Code Block
  cp -r $XILINX/bin/lin64 /tmp/xilinx

  on the machine on which the drivers are to be installed
  • If a 32 bit machine, use cp -r $XILINX/bin/lin /tmp/xilinx
• Modify /tmp/xilinx/lin64/setup_pcusb:
  • Force it to use udev by changing the lines:

    Code Block
    TP_USE_UDEV="0" TP_UDEV_ENABLED=`ps -e | grep -c udevd`

    to:

    Code Block
    TP_USE_UDEV="1" TP_UDEV_ENABLED="1"

  • Make the script executable (chmod +x setup_pcusb)
• Execute it (./setup_pcusb)
  Apparently errors are ignorable. Output looks something like:

  Code Block

  --File /usr/share/xusbdfwu.hex does not exist. --Error getting file version for /usr/share/xusbdfwu.hex. --Updating xusbdfwu.hex file. --File /usr/share/xusb_xlp.hex does not exist. --Error getting file version for /usr/share/xusb_xlp.hex. --Updating xusb_xlp.hex file. --File /usr/share/xusb_emb.hex does not exist. --Error getting file version for /usr/share/xusb_emb.hex. --Updating xusb_emb.hex file. --File /usr/share/xusb_xpr.hex does not exist. --Error getting file version for /usr/share/xusb_xpr.hex. --Updating xusb_xpr.hex file. --File /usr/share/xusb_xup.hex does not exist. --Error getting file version for /usr/share/xusb_xup.hex. --Updating xusb_xup.hex file. --File /usr/share/xusb_xp2.hex does not exist. --Error getting file version for /usr/share/xusb_xp2.hex. --Updating xusb_xp2.hex file. --File /usr/share/xusb_xse.hex does not exist. --Error getting file version for /usr/share/xusb_xse.hex. --Updating xusb_xse.hex file. --File /etc/udev/rules.d/xusbdfwu.rules exists. --File /etc/udev/rules.d/xusbdfwu.rules version = 0003 --File xusbdfwu.rules exists. --File xusbdfwu.rules version = 0003 --File xusbdfwu.rules is already updated.

• Ensure the hex files were installed in /usr/share

  Code Block

  $ ls -l /usr/share/*.hex -rw-r--r-- 1 root bin 21708 Feb 9 13:30 /usr/share/xusb_emb.hex -rw-r--r-- 1 root bin 21708 Feb 9 13:30 /usr/share/xusb_xlp.hex -rw-r--r-- 1 root bin 22956 Feb 9 13:30 /usr/share/xusb_xp2.hex -rw-r--r-- 1 root bin 20740 Feb 9 13:30 /usr/share/xusb_xpr.hex -rw-r--r-- 1 root bin 22956 Feb 9 13:30 /usr/share/xusb_xse.hex -rw-r--r-- 1 root bin 21666 Feb 9 13:30 /usr/share/xusb_xup.hex -rw-r--r-- 1 root bin 21666 Feb 9 13:30 /usr/share/xusbdfwu.hex

  If the permissions or ownership aren't as above, change them
• Ensure the rules were installed in /etc/udev/rules.d

  Code Block
  $ ls -l /etc/udev/rules.d/xusbdfwu.rules -rw-r--r-- 1 root root 987 Feb 9 15:04 xusbdfwu.rules

  If the permissions or ownership isn't as above, change them
• Plug a dongle into a USB port
• Use lsusb to see whether a line like Bus 002 Device 013: ID 03fd:0008 Xilinx, Inc. appears
  You should find a file called /proc/bus/usb/<Bus>/<Device>
• Use dmesg to look for errors. When it's working properly, you'll see something like:

  Code Block
  usb 2-1: new high speed USB device using ehci_hcd and address 13 usb 2-1: New USB device found, idVendor=03fd, idProduct=0008 usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 2-1: Product: XILINX usb 2-1: Manufacturer: XILINX usb 2-1: configuration #2 chosen from 1 choice

• If it's not working properly, try running the fxload command found in /etc/udev/rules.d/xusbdfwu.rules by hand. Use the one that has the same idVendor and idProduct given in the dmesg output. Use /proc/bus/usb/<Bus>/<Device> for $tempnode.
• The drivers are loaded when the dongle's light is either amber or green.
