基于OpenOCD的嵌入式远程调试系统的研究与实现

Embedded Remote Debugging System Based on OpenOCD

近年来,国内嵌入式芯片技术飞速发展,适配国产化芯片的嵌入式软件开发环境越来越重要。以研究嵌入式开发环境为目的,选定Cortex-M架构芯片为调试目标,FTDI2232芯片为JTAG信号转换芯片,基于OpenOCD实现了一套嵌入式远程调试系统,完成了添加断点、删除断点、单步运行、继续运行等常用的调试命令以及查看目标芯片信息的基本指令,验证了远程调试系统的可行性与正确性,为后续开发国产化嵌入式软件开发环境奠定了基础。

In recent years,the rapid development of embedded chip technology in China has made it increasingly important to adapt to the embedded software development environment of domestically produced chips.This paper aims to study the embedded development environment,selecting chip based on Cortex-M architecture as the debugging target,and the FTDI2232 chip as the JTAG signal conversion chip.Based on OpenOCD,an embedded remote debugging system was implemented,successfully executing commonly used debugging commands such as adding breakpoints,deleting breakpoints,stepping,and continuing to run,as well as basic instructions for viewing target chip information,The feasibility and correctness of the remote debugging system have been verified.
