Over on Embedded Star is an article about debugging Linux kernel and applications. The increasing popularity of high-speed 32-bit ARM based microcontrollers allowed Linux to enter the world of embedded devices. That is why the need for debugging its kernel and applications have become essential. Since Linux is a true multi-process operating system, it utilizes a Memory Management Unit (MMU) to give each process a separate memory space. The MMU is also responsible for the protection of each process’s memory space against each other. The switching among different processes complicates debugging, so the aticle will show you how to debug Linux kernel and applications.
