Description: In this paper, the design and implementation of general bootloader based on ARM embedded system is studied. The Bootloader is a piece of code that executes in the embedded system before the kernel operating system, and its primary role is to load the kernel image.
On practice platform, this topic has been used in the hardware Intel Xscale wasn't entirely series PXA255 as processor, Xscale wasn't entirely core is compatible with ARM V5TE framework, thus has certain representativeness, and practice in order to set up subject hardware platform, software in Linux as the operating system. In the realization of the specific goal is in addition to realize the basic function of bootloader, will it into a more complex system, namely to increase support for hardware circuit board, to facilitate developers debug and development. Therefore, this paper focuses on the practical design, concrete implementation and simple evaluation of its role. Finally, the implementation of the bootloader is expanded: in order to clarify some common features of the bootloader in the ARM embedded system, this paper introduces how to carry out the transplantation of other ARM systems to achieve universality.
