1 | This library emulates Jungo Windrvr USB functions in userspace which are |
2 | required by XILINX impact to access the Platform cable USB. With this library |
3 | it is possible to access the cable without loading a proprietary kernel module |
4 | which breaks with every new kernel release. It uses the USB functions provided |
5 | by the libusb userspace library instead and should work on every kernel version |
6 | which is supported by libusb. It was written against impact from ISE Webpack |
0b50c513 |
7 | 9.1SP1 and tested with the following software: |
8 | |
9 | * ISE Webpack 9.1SP2 |
10 | * ISE Webpack 9.1SP1 |
11 | * ISE Webpack 8.1SP3 |
12 | * ChipScope 9.1.02i |

14 | Build the library by calling `make'. |
15 | |
16 | To use this library you have to preload the library before starting impact: |
17 | |
18 | $ LD_PRELOAD=/path/to/libusb-driver.so impact |
19 | or |
20 | $ export LD_PRELOAD=/path/to/libusb-driver.so (for sh shells) |
21 | $ setenv LD_PRELOAD /path/to/libusb-driver.so (for csh shells) |
22 | $ impact |

24 | To use the device as ordinary user, put the following line in a new |
25 | file in /etc/udev/rules.d/ and restart udev: |
26 | ACTION=="add", BUS=="usb", SYSFS{idVendor}=="03fd", MODE="666" |

29 | If your cable does not have the ID 03fd:0008 in the output of lsusb, |
30 | the initial firmware has not been loaded (loading it changes the |
31 | product-ID from another value to 8). To load the firmware follow |
32 | these steps: |

34 | 1. If you have no /etc/udev/rules.d/xusbdfwu.rules file, copy it from |
35 | /path/to/ISE/bin/lin/xusbdfwu.rules to /etc/udev/rules.d/xusbdfwu.rules |

36 | |
37 | 2. Install the package containing /sbin/fxload from your linux distribution. |
38 | It is usually called "fxload" |
39 | |
40 | 3. copy the file /path/to/ISE/bin/lin/xusbdfwu.hex to /usr/share/xusbdfwu.hex |
41 | |
42 | 4. restart udev and re-plug the cable |
