No matter how you approach it, Linux debugging will always be complex. The first part of this Short Cut examines some of these complexities as they relate to kernel debugging and present ideas and methods to improve your debugging skills, inside the kernel itself and then inside device drivers. You begin by learning to use Kernel GNU Debugger (KGDB) to probe the kernel.

As embedded systems grow more complex, developers are integrating full-fledged operating systems into them. Linux is an especially attractive option: it supports virtually all hardware architectures and many peripherals, scales well, offers full source code, and requires no royalty payments. However, building custom versions of Linux for new embedded systems has traditionally been difficult.
Linux Fundamentals
Linux Kernel Development details the design and implementation of the Linux kernel, presenting the content in a manner that is beneficial to those writing and developing kernel code, as well as to programmers seeking to better understand the operating system and become more efficient and productive in their coding. The book details the major subsystems and features of the Linux kernel, including its design, implementation, and interfaces.
Real-time and embedded systems face the same development challenges as traditional software: shrinking budgets and shorter timeframes. However, these systems can be even more difficult to successfully develop due to additional requirements for timeliness, safety, reliability, minimal resource use, and, in some cases, the need to support rigorous industry standards.
