This book and CD-ROM set details the interaction of the firmware and hardware during the critical first few seconds after the microprocessor is powered up. It also describes minimal footprint features that can make firmware development more convenient and more productive. By focusing on these critical junctures where software meets hardware, readers are given a powerful and concrete introduction to what makes embedded development different from application development. Each critical step in the start-up process and the development process is explained in detail. Then the book shows how to combine these various critical components (flash file system, extensive command line interface through serial port and/or UDP, TFTP/XMODEM data transfer, DHCP/BOOTP startup and more) into a sophisticated embedded system boot platform that can be used to implement a run-time environment on a wide range of microprocessor based systems. The companion CD-ROM includes the complete source and user documentation for the platform plus some of the MicroCross GNU X-Tools compiled for Windows are included for cross compilation and debug. Ed Sutter started his career with AT&T Bell Labs in 1981. Now a distinguished member of the technical staff (DMTS) at Lucent, he has been working in embedded systems since 1983. Starting with the 8085, Ed has worked with a wide range of systems over the years including most of today's common CPU architectures. He has put his experience in developing hardware, firmware, and software to good use by building several different development environments. While he is most comfortable with C and assembly language on embedded systems, he has developed code for Win32 and Unix varieties as well. His firmware tools have recently been the subjects of articles in Embedded Systems Programming and Circuit Cellar OnLine magazines. Tags: embedded systems firmware demystified |
