摘要
对Bootloader的启动流程进行分析。结合串行Flash自身特殊的物理组织结构,基于AMBA AHB总线接口设计了一款高速SPI总线,以增强Bootloader对串行Flash的读写操作功能。将串行Flash上存储的Bootloader拷贝到DDR SDRAM中执行,完成Bootloader从串行Flash的启动,实现了引导Linux操作系统内核启动的目的。
The booting process of Bootloader was analyzed.In order to enhance the reading and writing function of Bootloader to serial Flash,a high-speed SPI bus based on AMBA AHB bus was designed combined with the special physical organization structure of the serial Flash.Bootloader stored in the serial Flash was copied to DDR SDRAM and then was executed.As a result,the booting of Bootloader from serial Flash was completed and the aim of the booting of Linux operation system kernel was realized.
