基于ColdFirc的嵌入式调试系统的设计与实现 基于ColdFirc的嵌入式调试系统的设计与实现 中文摘要 中文摘要 嵌入式软件的特殊性使得其开发过程比传统的通用计算机软件要复杂得多，而调 试作为嵌入式系统开发中的关键环节，扮演着十分重要的角色。目前，国内在嵌入式 调试技术方面所做的研究工作较少，一般嵌入式开发调试工具都使用国外产品。因此， 深入研究嵌入式调试技术并研发自己的开发调试工具具有重要意义。 为了缓解国内嵌入式开发调试工具严重依赖进口、开发资料较少等一系列问题， 本文针对国内外市场发展迅猛的ColdFire微处理器，使用基于GDB调试器的远程调 试方式，设计并实现了一套ColdFire嵌入式调试系统，包括硬件调试平台 SDMCF52233EVB、调试桩GDBStub for ColdFire以及宿主机端集成调试软件SD．IDE for ColdFire，为用户提供了一种功能完备、操作简单、价格低廉、能满足学习和开发 双重需求的集成调试平台。 本文详细阐述了ColdFire调试系统的开发流程。首先分析了GDB相关调试技术 并给出了本调试系统的实现结构框架；其次给出了硬件调试平台SDMCF52233EVB 的最小系统设计、各硬件功能模块的实现方案以及硬件测试流程；随后在借鉴 GDBStub的一般调试原理和工作机制的基础上，设计并实现了GDBStub for ColdFire， 以作为目标机端调试代理，配合GDB完成调试；最后按模块讨论了宿主机端集成调 试软件SD．IDE for ColdFire的实现，包括添加工程模板、交叉编译、代码写入和代码 调试。本课题的研究成果为开发基于其他型号微处理器的调试系统以及类似的嵌入式 产品提供了借鉴和参考。 关键词：ColdFire，MCF52233，GDB，远程调试，调试桩 作 者：陈祠； 指导老师：王宜怀 ABSTRACT ABSTRACT Design and Implementation ofEmbedded Debugging Syaem based ColdFire ABSTRACT The speciality of embedded software makes its development much more complicated than the traditional general computer software’S．Debugging as a critical process in the embedded development，plays a very important role．Currently,there is little domestic research in the area of embedded debugging．The developing and debugging tools are provided bY foreign companies generally．So it is greatly meaning to study the embedded debugging technology deeply and develop the tools of ourselves． To ease a series of problems such as too much dependency on import tools and lacking of development documents interiorly,we aim at ColdFire CPUs which are rapidly enlarged in the national market，adopt the remote debugging method based on GDB to design and implement a ColdFire embedded debugging system including hardware debugging platform SDMCF52233EVB，debugging stub GDBStub for ColdFire and integated debugging software SD—IDE for ColdFire in the host．It provides an integated debugging platform、耐tll full function,simple operation and low price to meet the needs of both study and develo
