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 28In addition to the XILINX USB and parallel cables, devices based on the FTDI
292232 serial converter chip are also experimentally supported. This includes
30devices like the Amontec JTAGkey(-Tiny).

b8b5059a 32Build the library by calling `make'. If you are on a 64 bit system but want
1dd0c369
MG
33to build a 32 bit library, run `make lib32' instead. Be sure to have the 32
34bit versions of libusb-devel and libftdi-devel installed!

36To use this library you have to preload the library before starting impact:
37
38$ LD_PRELOAD=/path/to/libusb-driver.so impact
39or
40$ export LD_PRELOAD=/path/to/libusb-driver.so (for sh shells)
41$ setenv LD_PRELOAD /path/to/libusb-driver.so (for csh shells)
42$ impact

54Notes for the USB cable
55=======================
56
57To use the device as an ordinary user, put the following line in a new
e8f8e2d0 58file "libusb-driver.rules" in /etc/udev/rules.d/ and restart udev:
fdd05738 59ACTION=="add", BUS=="usb", SYSFS{idVendor}=="03fd", MODE="666"
979132fe 60
61
62If your cable does not have the ID 03fd:0008 in the output of lsusb,
63the initial firmware has not been loaded (loading it changes the
64product-ID from another value to 8). To load the firmware follow
65these steps:
66
c2e95a30 671. If you have no /etc/udev/rules.d/xusbdfwu.rules file, copy it from
68 /path/to/ISE/bin/lin/xusbdfwu.rules to /etc/udev/rules.d/xusbdfwu.rules
979132fe 69
702. Install the package containing /sbin/fxload from your linux distribution.
71 It is usually called "fxload"
72
6af90678 733. copy the files /path/to/ISE/bin/lin/xusb*.hex to /usr/share/
979132fe 74
754. restart udev and re-plug the cable
54357994 76
77

MG
78If you have multiple cables connected, you can specify the cable to use
79in the XILINX_USB_DEV environment-variable as "bus:device".
80These identifiers are available in the output of lsusb:
81Bus 001 Device 004: ID 03fd:0008 Xilinx, Inc.
82 ^^^ ^^^
83To use this cable, set the XILINX_USB_DEV variable to "001:004".
84
85
54357994 86Notes for the parallel cable
87============================
88
89To access the parallel port from userspace, the kernel needs to be built with
90the features "Parallel port support" (CONFIG_PARPORT), "PC-style hardware"
91(CONFIG_PARPORT_PC) and "Support for user-space parallel port device drivers"
92(CONFIG_PPDEV) builtin or as modules. If these features are built as modules,
93they need to be loaded before using this library.
94These modules are called:
95parport
96parport_pc
97ppdev
98
99
100To use the device as an ordinary user, put the user in the group 'lp'
6f766a61 101
102
cdc9c5bf 103If you have an almost compatible cable which works with other software but not
05e1bfcd 104with Impact, try adding -DFORCE_PC3_IDENT to the CFLAGS line in the Makefile.
105This enables a hack by Stefan Ziegenbalg to force detection of a parallel cable.
cdc9c5bf 106
107
6f766a61 108Parallel Cable IV is currently only supported in 'compatibility mode', as no
109attempt to configure the ECP registers is done by this library.
0c71f276 110
111
112If you get "Programming failed" or "DONE did not go high" when programming
113through the parallel cable with Impact 9.1, make sure to have the option "Use
114HIGHZ instead of BYPASS" enabled in Edit -> Preferences -> iMPACT Configuration
115Preferences.
116If you are using batch mode, add the following line to your cmd file:
117setPreference -pref UseHighz:TRUE
7606d470 118(This problem also occurs on windows and when using the real windrvr in linux
119and is solved with the same workaround. Impact 8.2 is working fine with the same
0c71f276 120boards and designs)
7606d470 121
122
123Notes for FTDI 2232 based cables
124================================
125
126To build the driver with FTDI 2232 support, you need to have libftdi and
127the libftdi development package installed. On debian, you can install both
128by installing 'libftdi-dev'.
129
130To set-up the device:
1311. Find out the vendor and product id of your cable using lsusb:
132 Bus 003 Device 005: ID 0403:cff8 Future Technology Devices ...
133 ~~~~~~~~~
134
1352. Copy the sample libusb-driverrc to ~/.libusb-driverrc, edit it and replace
19020bc5 136 the vendor and product-id in the example file with the values provided in
137 the lsusb-output. You can also change the 'parallel port' which is mapped to
138 this cable. Impact sees the device at that port as a Parallel Cable III.
7606d470 139
1403. To use the device as an ordinary user, put the following line in a new file
141 in /etc/udev/rules.d/ and restart udev:
142 ACTION=="add", BUS=="usb", SYSFS{idVendor}=="0403", SYSFS{idProduct}=="cff8", MODE="666"
143 (replace the vendor and product id with your values)
144
dc587d11 145The support for FTDI 2232 based devices is experimental and they are currently
1830118e 146significantly slower than the other supported cables.

150=============
151
152If you get the message 'The cable is being used by another application.' from
153impact, try running the following command:
154
155echo -e 'cleancablelock\nexit' | impact -batch
