OpenXenium CPLD and FLASH programmer

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 [UPDATED to support latest Raspberry PI OS (Bullseye)] :

• This has only been tested on PI Zero W and PI 3B+ model, but should work for all.

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!
