Abstract: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 presentedin detail.Finally the expanded testing functions are given for the testing of the electronic device on the board.
Keywords:bootloader  embedded system  microprocessor  Linux OS  BSP
