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.hfile - If you edited the
XeniumDefines.hfile, make sure to run./installagain

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!
