Migrating from x86 to PowerPC, Part 1: Robots and networked appliances on a shoestring
This series on embedded development shows you how to migrate a project prototype from x86 to PowerPC. This initial installment explains the realities and rationale of the project: it introduces the robotic submarines that were the start of the project (and where they came from), and describes the Linux/GCC development environment and the bare-bones Kuro Box PowerPC development board.

Migrating from x86 to PowerPC, Part 2: Anatomy of the Linux boot process
This installment of "Migrating from x86 to PowerPC" discusses detailed similarities and differences between booting Linux on an x86-based platform (typically a PC-compatible SBC) and a custom embedded platform based around PowerPC, ARM, and others. It discusses suggested hardware and software designs and highlights the tradeoffs of each. It also describes important design pitfalls and best practices. 		Articles 08 Feb 2005  
 
Migrating from x86 to PowerPC, Part 3: Kuro Box Linux up close
This installment of "Migrating from x86 to PowerPC" moves from the abstract to the concrete, looking into implementation details of the Kuro Box. Lewin Edwards shows how to get the box configured with development tools and device drivers installed and updated. 		Articles 08 Mar 2005  
 
Migrating from x86 to PowerPC, Part 4: Build a minimal embedded Web interface
This installment shows you how to use small-footprint, highly portable, Free Software tools to Web-enable your unmanned submarine, in anticipation of browsing its onboard photo library from an underground lair in the next episode. 		Articles 05 Apr 2005  
 
Migrating from x86 to PowerPC, Part 5: Create a Kuro-based Web album
In the fifth article of the Migrating from x86 to PowerPC series, Lewin Edwards shows how to get a photo album running on the Kuro Box. In the process, he covers embedded systems design goals, Web server security, and shows off a few handy tricks for off-loading processing work to the client system. 		Articles 17 May 2005  
 
Migrating from x86 to PowerPC, Part 6: Add vision to your robot submarine
In this episode of the ongoing Kuro Box project, learn how to add a USB camera to the machine. This article includes example Linux code to initialize and read from a USB camera through Video4Linux. Also find a brief introduction to edge detection techniques in captured images. 		Articles 21 Jul 2005  
 
Migrating from x86 to PowerPC, Part 7: Basic design of the vehicle control module
Get an overview of some design decisions involved in configuring a secondary processor to handle maintenance tasks on your robot submarine, and see some of the setup code allowing the subordinate processor to interact with the main system. 		Articles 06 Sep 2005  
 
Migrating from x86 to PowerPC, Part 8: Add stepper motors to the vehicle control module
Lewin Edwards reviews the I/O expansion possibilities for the slave microcontroller on the robot submarine. The Inter-IC Communication (I2C) bus provides a simple and compatible way to expand the submarine's I/O options and connect it to a number of stepper motors. 		Articles 11 Oct 2005  
 
Migrating from x86 to PowerPC, Part 9: Sensors, sensors, sensors!
From schematics to code, get a leg up on building your own robot submarine. Building on previous successes, Lewin Edwards shows how to add more sensors to your submarine, looking at the design requirements of different sensors and ways of sanity checking the results they provide.
