OpenXenium JTAG and Flash Memory programmer

The tools in this repo will allow you to use a Raspberry PI or an Onion Omega2+ to program an OpenXenium chip with the Xilinx CPLD Firmware via JTAG and will also upload XeniumOS images into the OpenXenium Flash memory via a custom 4-bit bus NOR Flash programming protocol.

** Read the XBOX BIOS INJECTION write up for gory details **

Raspberry PI:

• This has only been tested on PI Zero W and PI 3B+ models so far.
