| | 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 |
| | 11 | on Linux, the proprietary kernel module <i>windrvr</i> from <a href="http://www.jungo.com">Jungo</a> |
| | 12 | is needed to access the parallel- or usb-cable. |
| | 13 | As this module does not work with current linux kernel versions (> 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 |
| | 19 | <a href="http://people.redhat.com/twaugh/parport/html/x623.html">ppdev</a> interface to communicate |
| | 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> |
| | 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> |
| | 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. |
| | 32 | </P> |
| | 33 | <P><B>News</B> |
| | 34 | <UL> |
| | 35 | <LI><P><I>2008-03-26</I>: Xilinx has released their own drivers based on libusb with ISE Design Suite 10.1. |
| | 36 | To use them, you need to set the environment-variable <kbd>XIL_IMPACT_USE_LIBUSB</kbd> to <kbd>1</kbd> |
| | 37 | before running the tools. The driver on this page no longer needs to be preloaded if you only used |
| | 38 | it to access USB cables. Parallel port support still seems to rely on <i>windrvr</i>, which can be |
| | 39 | emulated by <i>libusb-driver</i>.</P> |
| | 40 | <P><B>Using 32-bit ISE 10.1 on a 64-bit platform:</B> When using the 32-bit JTAG tools from ISE Design |
| | 41 | Suite 10.1 on a 64-bit machine, the tools will not connect to the cable but output the following |
| | 42 | error: <I>Cable operation is not supported when running the 32-bit version of the application on a |
| | 43 | 64-bit platform.</I> |
| | 44 | To fix this, run the tools with <KBD>linux32</KBD> or preload the newest 32-bit version of |
| | 45 | <i>libusb-driver</i>. This will lead the tools to believe that they are running on a 32-bit |
| | 46 | platform and allows them to connect to the cable.</P></LI> |
| | 47 | |
| | 48 | <LI><P><I>2009-05-31</I>: ISE Design Suite 11.1 now uses their libusb based drivers as default, without |
| | 49 | the need to set <kbd>XIL_IMPACT_USE_LIBUSB</kbd>. If you want to use this driver with ISE 11.1 for USB |
| | 50 | cables and disable the builtin support for libusb, you now have to set <kbd>XIL_IMPACT_USE_LIBUSB</kbd> |
| | 51 | to <kbd>0</kbd> (<kbd>export XIL_IMPACT_USE_LIBUSB=0</kbd> or <kbd>setenv XIL_IMPACT_USE_LIBUSB 0</kbd>). |
| | 52 | For parallel cables Xilinx still relies on <i>windrvr</i>. This library works fine with parallel cables and |
| | 53 | ISE 11.1 with no need for <i>windrvr</i>.</P></LI> |
| | 54 | |
| | 55 | <LI><P><I>2010-03-15</I>: If you are using newer udev-versions (like the version included in Debian Squeeze |
| | 56 | and Ubuntu 9.10), then the file <i>/etc/udev/rules.d/xusbdfwu.rules</i> is incompatible with this udev |
| | 57 | version. The effect of this is that the cable-firmware gets never loaded and the cable led never lights up.</P> |
| | 58 | <P>To fix this, run the following command as root:<BR> |
| | 59 | <kbd>sed -i -e 's/TEMPNODE/tempnode/' -e 's/SYSFS/ATTRS/g' -e 's/BUS/SUBSYSTEMS/' /etc/udev/rules.d/xusbdfwu.rules</kbd><BR> |
| | 60 | You may have to reboot for this change to take effect.</P></LI> |
