嵌入式Bootloader机制的分析与移植

Analysis and Transplant of Embedded Bootloader Mechanism

由于嵌入式系统的专用性和多样性,嵌入式启动引导程序(Bootloader)的移植工作繁琐复杂。为了减少Bootloader移植工作的盲目性,加速产品进入市场的时间,以U-Boot-1.1.1为例,对嵌入式Bootloader进行分析,结合HHPPC852T嵌入式开发板的具体情况,提出在嵌入式系统上移植Bootloader的一般方法,该方法简单可行。

Due to the specialty and diversity of the embedded systems, much tedious transplant work must be done when embedded Linux is deployed on the target embedded system. In order to overcome the blindness of transplant work and speed up the entry markets time of the embedded products, a brief introduction to the embedded system Bootloader（U-Boot as an example） is given, with emphasis on its basic structure and mechanism. Based on the implementation of transplanting U-Boot to HHPPC852T target, a typical method for transplanting Bootloader to a new target is presented, which is simple and practicable.
