Development and Optimization of Embedded μ Clinux Bootloader

The purpose of bootloader development is to build optimized booting environment in which embedded operating system is able to correctly operate with specific hardware platform.This paper expatiates on the design roadmap of development of μClinux bootloader and describes the way to download kernel,which is based on programming implementation.At the same time,it presents the solution to optimize the process of transporting kernel file and improves system's portability.This solution uses UU(Unix to Unix) algorithm to encode and decode kernel files during transporting process,which proves to be feasible in practice.
