Transplant and Realization of Bootloader Object Based on PXA270 Embedded Systems

Liu Jian-she

Abstract

In order to meet the configuration diversity and flexibility of embedded operating system and hardware platform,Bootloader is designed to initialize basic hardware and boot the operating system kernel.Based on PXA270,transport methods and procedures of embedded system Linux Bootloader is summarized;The design and implementation of Bootloader is introduced;The application of position independent code in the Bootloader is discussed;Based on Bootloader,extended function for testing embedded hardware interface is described.In addition to complete the basic functions of Bootloader,position independent code is applied to boot fast,expanded function is used to test the basic hardware of PXA270.Direct reference can be provided to the similar system.
