ARM VxWorks Embedded Systems Practical Tutorial Guide
📘 Overview #
This book is part of the ARM Embedded Technology Series Tutorials. It provides a hands-on introduction to developing embedded systems using VxWorks on ARM platforms, with a strong focus on real-world engineering workflows.
Using the JX2410 experimental platform and the S3C2410 processor, the material walks through the complete embedded system lifecycle: development environment setup, BSP porting, driver implementation, and application-level development. It also demonstrates debugging workflows using Wind River’s Tornado II IDE.
The content is suitable both as a structured learning path for beginners and as a technical reference for experienced VxWorks engineers.
