- # ixo-usb-jtag - Emulation of a Altera Bus Blaster I on a Cypress FX2 IC.
- #
- # 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

- # 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 driver.

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