		<H1>XILINX JTAG tools on Linux without proprietary kernel modules</H1>
		<H2>About</H2>
		<P>
		When using <a href="http://www.xilinx.com">XILINX</a> JTAG software like Impact, Chipscope and XMD
		on Linux, the proprietary kernel module <i>windrvr</i> from <a href="http://www.jungo.com">Jungo</a>
		is needed to access the parallel- or usb-cable.
		As this module does not work with current linux kernel versions (&gt; 2.6.18) a library was developed,
		which emulates the module in userspace and allows the tools to access the JTAG cable without the need
		for a proprietary kernel module.
		</P>
		<P>
		The library uses <a href="http://libusb.sourceforge.net/">libusb</a> to access USB devices and the
		<a href="http://people.redhat.com/twaugh/parport/html/x623.html">ppdev</a> interface to communicate
		with parallel cables. The parallel part currently only supports Parallel Cable III mode (and PCIV in
		PCIII compatibility mode) as the faster PCIV modes use another kernel module which is not emulated by
		this library. So you are limited to a 200kHz JTAG clock when using Parallel Cable IV with this software.
		The USB cable is supported at full speed.
		</P>
		<P>
		Experimental support for FTDI 2232 based devices has been added. They are seen by Impact as a Parallel
		Cable III. These devices are currently significantly slower than every other supported cable.
		</P>
		<P>
		The library is called <i>libusb-driver</i> as it was developed to support the USB cable, but later
		extended to also support parallel cables.
		</P>
		<P><B>News</B> (<I>2008-03-26</I>): Xilinx has released their own drivers based on libusb with ISE Design Suite 10.1.
		To use them, you need to set the environment-variable <kbd>XIL_IMPACT_USE_LIBUSB</kbd> to <kbd>1</kbd>
		before running the tools. The driver on this page no longer needs to be preloaded if you only used
		it to access USB cables. Parallel port support still seems to rely on <i>windrvr</i>, which can be
		emulated by <i>libusb-driver</i>.</P>
		<P><B>Using 32-bit ISE 10.1 on a 64-bit platform:</B> When using the 32-bit JTAG tools from ISE Design
		Suite 10.1 on a 64-bit machine, the tools will not connect to the cable but output the following
		error: <I>Cable operation is not supported when running the 32-bit version of the application on a
		64-bit platform.</I>
		To fix this, run the tools with <KBD>linux32</KBD> or preload the newest 32-bit version of
		<i>libusb-driver</i>. This will lead the tools to believe that they are running on a 32-bit
		platform and allows them to connect to the cable.
		</P>
