Welcome to the XINU for Routers Main Page. This is for documentation for our development process that began in the summer of 2006.

As this is a wiki, you can sign up and begin adding and editing content, uploading images, and generating the needed documentation for our efforts.

About this Project

This is an ongoing research and implementation project in the area of Operating Systems and Embedded Systems. Its goal is to port the XINU Operating System to the MIPS platform by specifically targeting LinkSys WRT54GL routers, with the hope that it can soon be used as the basis for classes on Operating Systems, Embedded Systems, and Networking classes.

The Embedded XINU project was conceived and is supervised by Dr. Dennis Brylow and is being conducted by both graduate and undergraduate students in the Math, Statistics, & Computer Science department of Marquette University in Milwaukee, Wisconsin. The first major phase of work on Embedded XINU took place in the Summer of 2006.

Guides to Replicate Our Work

In this section we are developing instructions so that other groups can benefit from the work we are doing. These guides can be followed more or less in order to create a relatively inexpensive platform for a custom operating system. As our work develops further, there will be more XINU-specific information.

  1. Install OpenWRT
  2. Modify the Linksys hardware
  3. Connect to a modified router
  4. Run your own code

Internal Documentation

Project Outline

  • Goals
  1. Infect WRT54GL Routers with a XINU kernel
  2. Develop XINU to a point where it can control the router's basic functions
  3. Use this platform for a course in embedded systems and/or networking

More Research

  • TODO: (concrete tasks)
    • XINU Tasks
      • Complete wired NIC driver.
      • Start on wireless NIC driver and "RoboSwitch".
      • Integrate XINU TCP/IP stack.
  • TOTHINK: (abstract goals and wishlists)
    • Learn more about the memory structure and underlying hardware.
    • How should the loader discover hardware parameters if CFE does not implement device enumeration?
    • How do we safely access flash memory without bricking the router?
