The tools in this repo will allow you to use a Raspberry PI to program the CPLD and Flash Memory chips of the OpenXenium via Jtag and a custom 4-bit bus NOR Flash programming protocol. Original project mentioned above allowed the use of an Onion Omega2+... This has been removed for this project.
- This has only been tested on PI Zero W and PI 3B+ models so far.

The scripts assumes user of "pi"... if using a different user, you'll need to manually change "pi" to your username in the scripts
- After the OS has been written to your SD card, insert SD card into PC.
- Add the following to the last line in "config.txt":
enable_uart=1- This is required to allow the PWR LED to function properly.
- Add the following to the last line in "config.txt":
- Save edit and eject SD Card. Insert SD card into Pi and boot up.
- Connect to the PI via SSH or Serial terminal
- If git is not installed, you need to install it:
sudo apt-get install git
- Clone this repo by running:
git clone https://github.com/dtomcat/AdvancedXeniumProgrammer.git - Change to program directory:
cd AdvancedXeniumProgrammer - Fix permission on install file:
chmod 755 install - Then run:
./install - Setup service to listen for button presses:
sudo cp xenium.service /etc/systemd/system/xenium.servicesudo systemctl daemon-reloadsudo systemctl enable xeniumsudo service xenium start
- Connect to the PI via SSH or Serial terminal
- Pull the latest code with:
git pull - Then run:
./install
- First: Programming CPLD with BIT BANG firmware
- Second: Programming Flash with specified OS
- Third: Verifying flash was programmed successfully
- Forth: Programing CPLD with OpenXenium firmware
Note: You will need to provide your own PrometheOS bin file. (save it in the /xenium-bin folder as promOS.bin)
- After the PI has fully booted and the green led is on...
- Press the FIRST button to program the OpenXenium with XeniumOS.
- Hold the FIRST button to program the OpenXenium with PrometheOS.
- Press the SECOND button to program the flash chip with XeniumOS. (**The CPLD must be programmed with the Bit Bang firmware or this will fail.)
- Hold the SECOND button to program the flash chip with PrometheOS. (**The CPLD must be programmed with the Bit Bang firmware or this will fail.)
- Press the THIRD button to program the CPLD with the OpenXenium Firmware.
- Hold the THIRD button to program the CPLD with the BitBang Firmware.
- Press the FOURTH button to clear any errors.
- Hold the FOURTH button to shutdown the Raspberry Pi.
This is good to do if you keep getting an error trying to program the chips. (Red LED remains on)
Note: You will need to provide your own PrometheOS bin file. (save it in the /xenium-bin folder as promOS.bin)
- Connect to the PI via SSH or Serial terminal
- Change dir to AdvancedXeniumProgrammer
- You can program CPLD and FLASH in one single step with XeniumOS (XOS).
- Run:
./xenium-programmer-smd
- Run:
- You can program CPLD and FLASH in one single step with PrometheOS (PromOS).
- Run:
./PromOS-programmer-smd
- Run:
- You can program just the CPLD in one two ways.
- To program the Bit Bang firmware:
- Run:
./BitBangOnly
- Run:
- To program the OpenXenium firmware:
- Run:
./OX-Only_SMD
- Run:
- To program the Bit Bang firmware:
- You can program just the Flash in oe of two ways. (The CPLD MUST have the Bit Bang Firmware loaded)
- To program XOS:
- Run:
./FlashOnly - To program PromOS:
- Run:
./FlashOnlyProm
- To program XOS:
- Run:
Just a quick and simple design I put together. I'm sure this thing could be improved upon greatly. Sharing for anyone wanting it.
NOTE: for the "light pipes", I just used some clear PLA (2.90mm not standard 1.75) filament.
Huge thanks to James Bolding for the Original Eagle PCB hardware design! This PCB design is based on his original work.
- 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!
There are a couple parts not listed in BOM that could be helpful.
- Pin headers 2.54 spacing
- 1 2x7 for LPC port
- 1 1x2 for 3v3 (Optionally... but connect two points with solder)
- Will need a 2-Pin Jumper/Bridge Cap if installing 1x2 pin header
- 6 Pogo pins (P75-E3 pogo pins seem to work the best)
- Koos du Preez - Creator ([email protected] - Comments, improvements, critique, etc. is welcome!)
- Dtomcat - SMD programmer PCB design and code split to allow status LEDs.
- James Bolding - Orignal hardware design and PCB!
- Ryzee119 - OpenXenium Firmware and hardware and all round awesomeness!
- XC3SPROG - Not sure who to thank here, but the source code was pivotal in making this work!
