# ixo-usb-jtag - Emulation of a Altera Bus Blaster I on a Cypress FX2 IC.
# #
# Kolja Waschk's USB-JTAG # The ixo-usb-jtag firmware can be loaded onto a bunch of different hardware
# including;
# * Xilinx USB Platform Cable
# * Many Digilent boards such as the Nexys, Nexys 2 and Atlys boards
# * Many fpga4fun.com boards from such as the Saxo and Xylo boards
# * The Numato Opsis
# #
# http://www.ixo.de/info/usb_jtag/ # Original version - http://www.ixo.de/info/usb_jtag/
# Updated version - http://ixo-jtag.sourceforge.net/
# Newest version - http://github.com/mithro/ixo-usb-jtag
# #
# Procedure for using is;
# * Get the ixo-usb-jtag firmware for your hardware (or build it yourself).
# * Load the firmware using the fxload tool.
# * Use openocd.
#
# Unless you burn the firmware into the EEPROM on your device, power cycling
# will require you to reload the firmware using the fxload tool. This can be
# automated by using udev rules (which can be found in the firmware
# repository).
#
# Ubuntu packages built from mithro's version (with prebuilt firmware and udev
# rules) can be found at

# TODO: Refactor the usb_blaster driver to allow loading firmware using any low
# level driver. Loading firmware is currently only supported on the ublast2
# driver but ixo-usb-jtag requires the ftdi or ftd2xx driver.

# ixo-usb-jtag is only compatible with the ublast1 protocol implemented via the
# ftdi or ftd2xx modes, using ublast2 will cause openocd to hang.
