【摘要】 嵌入式Linux的开发和应用越来越广泛,其中一个重要环节就是Linux内核的调试。Kgdb是一种插桩式、纯软件的嵌入式Linux的内核调试工具,主要应用于i386体系结构中。分析了kgdb的原理和它的实现过程,并在目前使用比较广泛的arm板上对kgdb进行了移植,主要包括串口驱动,陷阱处理和调试命令的移植3个部分。更多还原

【Abstract】 The development and application of the embedded Linux become more and more popular,and one important tache in the process is the kernel-debug.The kgdb which use the stub method is a software Linux kernel-debug tool and is most applicated on the i386 architecture.Kgdb’s theory and how to implement are analyzed;and kgdb is transplanted to the arm borad which is popular nowdays,including three portions: The uart driver,trap dispose and the transplant of the debug commands.更多还原
