This library emulates Jungo Windrvr USB functions in userspace which are
|
|
|
|
|
required by XILINX impact to access the Platform cable USB. With this library
|
|
|
|
|
it is possible to access the cable without loading a proprietary kernel module
|
|
|
|
|
which breaks with every new kernel release. It uses the USB functions provided
|
|
|
|
|
by the libusb userspace library instead and should work on every kernel version
|
|
|
|
|
which is supported by libusb. It was written against impact from ISE Webpack
|
|
|
|
|
9.1SP1 and will very probably not work with older impact versions (<9.1).
|
|
|
|
|
|
|
|
|
|
Build the library by calling `make'.
|
|
|
|
|
|
|
|
|
|
To use this library you have to preload the library before starting impact:
|
|
|
|
|
|
|
|
|
|
$ LD_PRELOAD=/path/to/libusb-driver.so impact
|
|
|
|
|
or
|
|
|
|
|
$ export LD_PRELOAD=/path/to/libusb-driver.so (for sh shells)
|
|
|
|
|
$ setenv LD_PRELOAD /path/to/libusb-driver.so (for csh shells)
|
|
|
|
|
$ impact
|
|
|
|
|
|
|
|
|
|
To use the device as ordinary user, put the following line in a new
|
|
|
|
|
file in /etc/udev/rules.d/ and restart udev:
|
|
|
|
|
ACTION=="add", BUS=="usb", SYSFS{idVendor}=="03fd", MODE="666"
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
If your cable does not have the ID 03fd:0008 in the output of lsusb,
|
|
|
|
|
the initial firmware has not been loaded (loading it changes the
|
|
|
|
|
product-ID from another value to 8). To load the firmware follow
|
|
|
|
|
these steps:
|
|
|
|
|
|
|
|
|
|
1. If you have no /etc/udev/rules.d/xusbdfwu.rules file, create one with the
|
|
|
|
|
following content:
|
|
|
|
|
# version 0001
|
|
|
|
|
SYSFS{idVendor}=="03fd", SYSFS{idProduct}=="0008", NAME="windrvr6"
|
|
|
|
|
BUS=="usb", ACTION=="add", SYSFS{idVendor}=="03fd", SYSFS{idProduct}=="0007", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusbdfwu.hex -D $TEMPNODE"
|
|
|
|
|
BUS=="usb", ACTION=="add", SYSFS{idVendor}=="03fd", SYSFS{idProduct}=="0009", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusbdfwu.hex -D $TEMPNODE"
|
|
|
|
|
BUS=="usb", ACTION=="add", SYSFS{idVendor}=="03fd", SYSFS{idProduct}=="000b", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusbdfwu.hex -D $TEMPNODE"
|
|
|
|
|
BUS=="usb", ACTION=="add", SYSFS{idVendor}=="03fd", SYSFS{idProduct}=="000d", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusbdfwu.hex -D $TEMPNODE"
|
|
|
|
|
BUS=="usb", ACTION=="add", SYSFS{idVendor}=="03fd", SYSFS{idProduct}=="000f", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusbdfwu.hex -D $TEMPNODE"
|
|
|
|
|
|
|
|
|
|
2. Install the package containing /sbin/fxload from your linux distribution.
|
|
|
|
|
It is usually called "fxload"
|
|
|
|
|
|
|
|
|
|
3. copy the file /path/to/ISE/bin/lin/xusbdfwu.hex to /usr/share/xusbdfwu.hex
|
|
|
|
|
|
|
|
|
|
4. restart udev and re-plug the cable
