54357994 1This library emulates Jungo Windrvr USB and parallel port functions in
2userspace which are required by XILINX impact to access the Platform cable USB
3and Parallel Cable III.
4With this library it is possible to access the cables without loading a
5proprietary kernel module which breaks with every new kernel release. It uses
6f766a61 6the functionality provided by the libusb userspace library for USB access and
54357994 7the kernel interface at /dev/parport0 for parallel port access instead and
8should work on every kernel version which is supported by libusb and supports
9ppdev. It was written against impact from ISE Webpack 9.1SP1 and tested with
10the following software:

7606d470 29In addition to the XILINX USB and parallel cables, devices based on the FTDI
302232 serial converter chip are also experimentally supported. This includes
31devices like the Amontec JTAGkey(-Tiny).

b8b5059a 33Build the library by calling `make'. If you are on a 64 bit system but want

34to build a 32 bit library, run `make lib32' instead. Be sure to have the 32
35bit versions of libusb-devel and libftdi-devel installed!

37To use this library you have to preload the library before starting impact:
38
39$ LD_PRELOAD=/path/to/libusb-driver.so impact
40or
41$ export LD_PRELOAD=/path/to/libusb-driver.so (for sh shells)
42$ setenv LD_PRELOAD /path/to/libusb-driver.so (for csh shells)
43$ impact

55Notes for the USB cable
56=======================
57
58To use the device as an ordinary user, put the following line in a new
e8f8e2d0 59file "libusb-driver.rules" in /etc/udev/rules.d/ and restart udev:
7b219d30 60ACTION=="add", SUBSYSTEMS=="usb", ATTRS{idVendor}=="03fd", MODE="666"
979132fe 61
62
63If your cable does not have the ID 03fd:0008 in the output of lsusb,
64the initial firmware has not been loaded (loading it changes the
65product-ID from another value to 8). To load the firmware follow
66these steps:
67
c2e95a30 681. If you have no /etc/udev/rules.d/xusbdfwu.rules file, copy it from
69 /path/to/ISE/bin/lin/xusbdfwu.rules to /etc/udev/rules.d/xusbdfwu.rules
979132fe 70
7b219d30
MG
712. If you are running a newer version of udev (as in Debian Squeeze and
72 Ubuntu 9.10), you need to adapt the rules-file to the new udev-version:
73 sed -i -e 's/TEMPNODE/tempnode/' -e 's/SYSFS/ATTRS/g' -e 's/BUS/SUBSYSTEMS/' /etc/udev/rules.d/xusbdfwu.rules
74
753. Install the package containing /sbin/fxload from your linux distribution.
979132fe 76 It is usually called "fxload"
77
7b219d30 784. copy the files /path/to/ISE/bin/lin/xusb*.hex to /usr/share/
979132fe 79
7b219d30 805. restart udev and re-plug the cable
54357994 81

83If you have multiple cables connected, you can specify the cable to use
84in the XILINX_USB_DEV environment-variable as "bus:device".
85These identifiers are available in the output of lsusb:
86Bus 001 Device 004: ID 03fd:0008 Xilinx, Inc.
87 ^^^ ^^^
88To use this cable, set the XILINX_USB_DEV variable to "001:004".

54357994 91Notes for the parallel cable
92============================
93
94To access the parallel port from userspace, the kernel needs to be built with
95the features "Parallel port support" (CONFIG_PARPORT), "PC-style hardware"
96(CONFIG_PARPORT_PC) and "Support for user-space parallel port device drivers"
97(CONFIG_PPDEV) builtin or as modules. If these features are built as modules,
98they need to be loaded before using this library.
99These modules are called:
100parport
101parport_pc
102ppdev
103
104
105To use the device as an ordinary user, put the user in the group 'lp'
6f766a61 106
107
cdc9c5bf 108If you have an almost compatible cable which works with other software but not
05e1bfcd 109with Impact, try adding -DFORCE_PC3_IDENT to the CFLAGS line in the Makefile.
110This enables a hack by Stefan Ziegenbalg to force detection of a parallel cable.
cdc9c5bf 111
112
6f766a61 113Parallel Cable IV is currently only supported in 'compatibility mode', as no
114attempt to configure the ECP registers is done by this library.
0c71f276 115
116
117If you get "Programming failed" or "DONE did not go high" when programming
118through the parallel cable with Impact 9.1, make sure to have the option "Use
119HIGHZ instead of BYPASS" enabled in Edit -> Preferences -> iMPACT Configuration
120Preferences.
121If you are using batch mode, add the following line to your cmd file:
122setPreference -pref UseHighz:TRUE
7606d470 123(This problem also occurs on windows and when using the real windrvr in linux
124and is solved with the same workaround. Impact 8.2 is working fine with the same
0c71f276 125boards and designs)

128Notes for FTDI 2232 based cables
129================================
130
131To build the driver with FTDI 2232 support, you need to have libftdi and
132the libftdi development package installed. On debian, you can install both
133by installing 'libftdi-dev'.
134
135To set-up the device:
1361. Find out the vendor and product id of your cable using lsusb:
137 Bus 003 Device 005: ID 0403:cff8 Future Technology Devices ...
138 ~~~~~~~~~
139
1402. Copy the sample libusb-driverrc to ~/.libusb-driverrc, edit it and replace
19020bc5 141 the vendor and product-id in the example file with the values provided in
142 the lsusb-output. You can also change the 'parallel port' which is mapped to
143 this cable. Impact sees the device at that port as a Parallel Cable III.
7606d470 144
1453. To use the device as an ordinary user, put the following line in a new file
146 in /etc/udev/rules.d/ and restart udev:
7b219d30 147 ACTION=="add", SUBSYSTEMS=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="cff8", MODE="666"
7606d470 148 (replace the vendor and product id with your values)
149
dc587d11 150The support for FTDI 2232 based devices is experimental and they are currently
1830118e 151significantly slower than the other supported cables.

155=============
156
157If you get the message 'The cable is being used by another application.' from
158impact, try running the following command:
159
160echo -e 'cleancablelock\nexit' | impact -batch
