# 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 |

|
|
|
# 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). |

# 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. |
