摘要
Bootloader(引导加载程序)是嵌入式系统开发的重要环节,它使得操作系统和硬件平台联系起来,对嵌入式系统的后继软件开发十分重要。介绍了Bootloader的特点及其在DM6446平台上的引导方式,分析了U-Boot的运行机制,给出了U-Boot在DM6446平台上的移植步骤和关键技术,修改和调试了U-Boot,最后对结果进行了测试并且稳定运行。这对基于DM6446处理器的产品开发有一定的参考价值。
Bootloader is an important part of linking up the operating system and hardware platform,and also important for embedded system of software development.The paper introduces the general characteristics of Bootloader and the start-up method about DM6446,analyzes the source code of U-Boot,explaines the porting step and key technology about U-Boot on the DM6446,constructes and debugges the code of U-Boot.In the end,the ported U-Boot works steadily in the embedded system after testing.It is useful to develop the product based on DM6446.
