5 # The ixo-usb-jtag firmware can be loaded onto a bunch of different hardware
7 # * Xilinx USB Platform Cable
8 # * Many Digilent boards such as the Nexys, Nexys 2 and Atlys boards

16 # Procedure for using is;
17 # * Get the ixo-usb-jtag firmware for your hardware (or build it yourself).
18 # * Load the firmware using the fxload tool.
21 # Unless you burn the firmware into the EEPROM on your device, power cycling
22 # will require you to reload the firmware using the fxload tool. This can be
23 # automated by using udev rules (which can be found in the firmware
