摘要
嵌入式系统由于其自身的特点,一般没有通用的Bootloader。而U-Boot是一款功能强大的Bootloader软件,它可以支持很多架构的CPU,但是U-Boot相对的也会比较复杂。通过对U-Boot的目录结构以及运行机制的详细分析,在此基础上结合飞利浦LPC2210微控制的硬件架构特点,对U-Boot进行移植。对移植成功的U-Boot代码进行测试分析表明,该移植是成功的,能够为使用LPC2000系列CPU进行嵌入式系统开放的人员提供一些参考。
Because of the characteristics of embedded system, there isn＇t an all-purpose Bootloader in it. U-boot is a powerful Bootloader, but it is also more complex than other Bootloaders. Analyzing the directory construction of U-Boot and its running mechanism, U-Boot is ported on LPC2210 based on the machine mechanism of this CPU. During analyzing the results of U-Boot ruing LPC2210, this porting is successful and the porting experiment maybe offer some experiences for someone, who use the CPU of LPC2000 series to build their embedded system.
