Author Anthony J. Massa shows you how to save thousands of dollars and hundreds of programming hours by effectively using the open-source eCos environment from market leader Red Hat. This workbook shows developers and managers the advantages of using eCos -- the Embedded Configurable Operating System -- over proprietary or commercial embedded operating systems. Overview - How to build low-cost, royalty-free embedded solutions with eCos
- Covers eCos architecture, installation, configuration, coding, debugging, bootstrapping, porting, and more
- Incorporates additional open-source software components to extend the features and functionality of eCos, meeting the requirements of a wide range of embedded systems
- Includes open-source tools for a complete embedded software development environment with eCos as the core
- Contains extensive code examples and complete application case study
"Anthony's book is easily the most complete treatment of eCos system development. I believe it is destined to become part of every eCos developer's library." —Michael Tiemann, CTO, Red Hat Software and Co-founder of Cygnus Solutions The Embedded Configurable Operating System (eCos) gives professionals a low-cost, royalty-free embedded software development solution that works in highly constrained hardware environments, while scaling smoothly to larger products. In this start-to-finish guide to eCos solution building, Anthony Massa covers eCos architecture, installation, configuration, coding, deployment, and the entire eCos open-source development system. Additional open-source tools are included to configure a complete embedded software development environment. Massa's code examples and application case study illuminate techniques for building virtually any embedded system, from the simplest device to complex Internet-enabled wireless systems. Coverage includes: - Understanding eCos architecture: kernel, hardware abstraction layer, and other components
- Preparing your eCos embedded development environment
- Incorporating additional open-source tools for a complete embedded software development environment
- Working with exceptions, interrupts, and virtual vectors
- Managing threads and synchronization
- Utilizing the eCos networking stack, I/O system, and file system
- Covering additional eCos functionality, including third-party open-source contributions
- Using RedBoot, the standardized embedded debug and bootstrap solution
- Porting eCos to new hardware platforms
The accompanying CD-ROM contains the complete eCos development environment, along with all the code presented in this book. Table of Contents Foreword Preface 1.
