摘　　要：讨论了启动引导程序在嵌入式系统开发过程中的作用,对启动引导程序的工作原理和实现方法做了详细的分析;介绍了Intel?PXA272微处理器的芯片体系结构特征和开发板UraniumV0.9的硬件平台结构;结合基于Intel?的PXA272的开发板UraniumV0.9的设计、研发和调试过程,详细说明开发板的启动引导程序的设计、实现方法;简述了启动引导程序为配合开发板器件的测试而扩展的部分测试功能。The function of the bootloader during the development of the embedded system is discussed. The operational principal and implement method of the bootloader are analyzed. Some information about the architecture of the Intel PXA272 processor and the hard- ware framework of the Uranium V0.9 are introduced. Based on the design and debugging of the Uranium V0.9 with the Intel PXA272 processor, the design and implementation of the embedded Linux＇s bootloader is presented in detail. Finally the expanded testing functions are given for the testing of the electronic device on the board.
