摘要
针对WinCE7.0嵌入式系统开发过程中,通过以太网(Ethernet)来下载系统镜像的EBoot存在诸多不足的问题,本文实现了通过SD卡下载WinCE7.0系统的EbootSD。对WinCE7.0的Bootloader的架构、引导过程、实现方法进行了详细阐述,并结合TI公司的Cortex-A8处理器AM3359的Beaglebone开发板硬件特性,完成了Bootloader的移植工作,实现了通过SD卡下载WinCE7.0系统镜像程序的设计。测试结果表明,该Bootloader达到了设计目标。
Aiming at the problem of downloading the EBoot of system image by Ethernet during the embedded system development with WinCET. 0,downloading EbootSD of WinCET. 0 system by SD card is realized. The framework, booting process and implementation method of WinCET. 0 Bootloader are introduced in detail. Using hardware features of Beaglebone development board based on TI＇s AM3359 （Cortex-AS processor）, Bootloader is transplanted,and downloading the mirror image program of WinCET. 0 system by SD is realized. Test result indicates that the Bootloader meets the design objectives.
