Embedded Linux: Hardware, Software, and Interfacing
Embedded Linuxcovers the development and implementation of interfacing applications on an embedded Linux platform. It includes a comprehensive discussion of platform selection, crosscompilation, kernel compilation, root filesystem creation, booting, remote debugging, real-world interfacing, application control, data collection, archiving, and presentation.This book includes serial, parallel, memory I/O, USB, and interrupt-driven hardware designs using x86-, StrongARM®-, and PowerPC®-based target boards. In addition, you will find simple device driver module code that connects external devices to the kernel, and network integration code that connects embedded Linux field devices to a centralized control center. Examples teach hardware developers how to store and activate field bits and deliver process information using open source software. If you are a hardware developer, software developer, system integrator, or product manager who's begun exploring embedded Linux for interfacing applications, this book is for you.Select an embedded Linux platform (x86, StrongARM®, and PowerPC®architectures are covered)Create a cross-compiling and debugging development environmentBuild a custom Linux kernel for each architectureCreate a minimum root filesystemBoot the custom Linux kernel on three target boards with x86, SA-1110, and MPC860 microprocessorsRemote debug programs running on a target board across an ethernet network using GNU toolsConnect data acquisition and control electronics/peripherals using the microprocessor's serial, parallel, memory I/O, and USB interfacesMeasure average interrupt latencies for the x86, SA-1110, and MPC860 microprocessors and design an interrupt-driven process timer with 1mS accuracyInterface the peripherals to the kernel and applications using device driver modulesCollect, control, store, and present data via open source protocols and applicationsAnalyze embedded Linux vendor product offerings0672322269B03282002
