嵌入式远程调试器的设计与实现

Design and Implementation of Embedded Remote Debugger

为解决嵌入式系统不支持本地调试,且开发周期较长的问题,提出了一种采用软件插桩技术针对嵌入式系统的远程调试方案;对嵌入式系统远程调试所采用的关键技术及其工作原理作了详细说明,介绍了调试器基本功能的实现过程、交叉调试所用到的远程通信协议,最后重点剖析了调试器的设计与实现要点;实践证明该设计方案较好地解决了嵌入式系统调试过程中受限于系统自身资源与空间的问题,缩短了系统开发周期,达到设计要求。

An approach adopting the technology of tnsertmg stub to implement embedded remote debugging is addressed in this paper. It introduces the key technology and the principle of the embedded remote debugging, then carries on the deep discussion into the primary functions and the communication protocol of debugger, at last emphasizes on the design and implementation of embedded remote debugger. Practice has proved that the approach has solved the problem of lacking resource and space of system during debugging. It also help to shorten systematic development period and has reached the designing requirement.
