摘要
嵌入式电子产品由于其专用性的特性,使得与硬件相关的软件需要经过移植才能使用。如何设计与移植设备开机第一个运行的代码引导程序Bootloader尤为重要。不同内核开发平台的Bootloader均需要重新修改及烧写。在此介绍了嵌入式软件分类、引导程序分类、Bootloader功能、设计方法,并分析U-Boot工作机制、移植具体方法。
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.
