Design and Portability of Embedded Software Bootloader
Because of its specificity of embedded electronic products, software related with hardware needs portability before use. How to design and transplant Bootloader which is the first code of device boot program is particularly important. Bootloader of different kernel development platforms need to modify and write. The embedded software classification, bootstrap program classification, function of Bootloader, program design method is introduced, and the working mechanism of U-Boot and the important method is analyzed.
