移动医疗系统的Bootloader设计与实现

Design and Implementation of Bootloader for M-health System

启动引导程序(Bootloader)是嵌入式系统加电后运行的第一段软件代码。但是由于嵌入式系统的专用性和多样性,Bootloader的移植工作繁琐复杂。为了减少Bootloader移植工作的盲目性,加速产品开发进程,进行Bootloader分析总结,并针对设计的基于嵌入式技术的移动医疗系统设计一种应用于其上的Bootloader。除基本内核镜像的引导与加载外,提供多接口下载模式,且易于不同CPU的移植与扩展,具有一定的实际应用价值和参考意义。

The Bootloader is the first run software code of embedded systems after power on.Due to the specific and diversity of embedded systems,it is too complex to complete Bootloader transplantation.In order to reduce the blindness of Bootloader transplantation and accelerate product development process,as for a M-health system based on embedded technology,Bootloader is analyzed and summarized.After that design an Bootloader for the application,which can provide multi-interface download means besides boot and loading support of kernel image,also easy to maintain and expand for different CPU,has a certain practical and reference for development.
