  1. # ixo-usb-jtag - Emulation of a Altera Bus Blaster I on a Cypress FX2 IC.
  2. #
  3. # The ixo-usb-jtag firmware can be loaded onto a bunch of different hardware
  4. # including;
  5. # * Xilinx USB Platform Cable
  6. # * Many Digilent boards such as the Nexys, Nexys 2 and Atlys boards
  7. # * Many fpga4fun.com boards from such as the Saxo and Xylo boards
  8. # * The Numato Opsis

  11. # Updated version - http://ixo-jtag.sourceforge.net/
  12. # Newest version - http://github.com/mithro/ixo-usb-jtag
  13. #
  14. # Procedure for using is;
  15. # * Get the ixo-usb-jtag firmware for your hardware (or build it yourself).
  16. # * Load the firmware using the fxload tool.
  17. # * Use openocd.
  18. #
  19. # Unless you burn the firmware into the EEPROM on your device, power cycling
  20. # will require you to reload the firmware using the fxload tool. This can be
  21. # automated by using udev rules (which can be found in the firmware
  22. # repository).
  23. #
  24. # Ubuntu packages built from mithro's version (with prebuilt firmware and udev
  25. # rules) can be found at

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