Welcome to the XINU for Routers Main Page. This is for developing 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.
Project Outline
- Goals
- Infect WRT54GL Routers with a XINU kernel
- Develop XINU to a point where it can control the router's basic functions
- Use this platform for a course in embedded systems and/or networking
- Hardware (Mod that LinkSys!)
- Why we add serial ports
- How we add serial ports
- Pictures of building
- Wiring Diagrams
- Chip Diagrams
- Software
- How to connect to a modified router
- Our Project's Directory Structure
- And then there was light: the Common Firmware Environment
- Interacting with the CFE Command Line Interface
- Fun freebies in the CFE API
- How code can Interface with CFE
- OpenWRT (When all else fails, steal it from Linux!)
- Important OpenWRT places of interest
- XINU (an O/S of our own)
