OpenXenium JTAG and Flash Memory programmer

* Read: "Home Brew" on ORIGINAL XBOX - a detailed article on why and how *

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.

Raspberry PI:

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

Onion Omega2+:

This has been tested and works on the Onion Omega2+.

INSTALLING THE XENIUM PROGRAMMER

Connect to the PI or Omega via SSH or Serial terminal
Clone this repo by running: git clone https://github.com/kooscode/xenium-programmer.git
Then run: ./install

UPDATING XENIUM PROGRAMMER

Connect to the PI or Omega via SSH or Serial terminal
Pull the latest code with: git pull
Then run: ./install

PROGRAMMING A XENIUM CPLD AND FLASH MEMORY

Connect to the PI or Omega via SSH or Serial terminal
You can program XeniumOS and OpenXenium Firmware in one single step.
Run: ./xenium-programmer

HOOKING UP THE HARDWARE

The JTAG and FLASH pins are configurable by editing the XeniumDefines.h file
If you edited the XeniumDefines.h file, make sure to run ./install again

PC BOARD

Huge thanks to James Bolding for the Eagle PCB hardware design. He made a kick-ass Schematic and PCB that you can make for the Raspberry PI Zero based programmer!

You can use the FREE Eagle PCB to load this up or just use the gerber files to have the PCB made at OSH Park!
