Designing and Porting Boot Loader and uClinux with Its Implementation Based on LPC2478

As various applications have been developped for different intention in Embedded System the combination of bootloader and uClinux which is as the base of those plays a more and more important role. uClinux,a linux distribution designed for processors without a Memory Management Unit (MMU), is the operating system that assorts with the device drivers, the platform for applications and the core of Embedded System. Additionally, the boot loader is a program that loads the main operating system. Transparently, boot loader which initializes necessary environment should execute before uClinux. Therefore, those two are feasible on LPC2478, a processor without MMU from NXP semiconductors. This paper introduces the configuration of boot loader and uClinux and represents a whole process of porting boot loader and uClinux on LPC2478.
