7 <H1>XILINX JTAG tools on Linux without proprietary kernel modules</H1>
8 <H2>About</H2>
9 <P>
10 When using <a href="http://www.xilinx.com">XILINX</a> JTAG software like Impact, Chipscope and XMD
2b78cb99 11 on Linux, the proprietary kernel module <i>windrvr</i> from <a href="http://www.jungo.com">Jungo</a>
026cbe49 12 is needed to access the parallel- or usb-cable.
13 As this module does not work with current linux kernel versions (&gt; 2.6.18) a library was developed,
14 which emulates the module in userspace and allows the tools to access the JTAG cable without the need
15 for a proprietary kernel module.
16 </P>
17 <P>
18 The library uses <a href="http://libusb.sourceforge.net/">libusb</a> to access USB devices and the
4d2daea0 19 <a href="http://people.redhat.com/twaugh/parport/html/x623.html">ppdev</a> interface to communicate
026cbe49 20 with parallel cables. The parallel part currently only supports Parallel Cable III mode (and PCIV in
21 PCIII compatibility mode) as the faster PCIV modes use another kernel module which is not emulated by
22 this library. So you are limited to a 200kHz JTAG clock when using Parallel Cable IV with this software.
23 The USB cable is supported at full speed.
24 </P>
25 <P>
7606d470 26 Experimental support for FTDI 2232 based devices has been added. They are seen by Impact as a Parallel
27 Cable III. These devices are currently significantly slower than every other supported cable.
28 </P>
29 <P>
026cbe49 30 The library is called <i>libusb-driver</i> as it was developed to support the USB cable, but later
31 extended to also support parallel cables.
