| 摘 要： | 启动装载过程是系统程序设计的必须部分,用以把存储器中的程序内容装载到CPU片内ROM中并启动系统。通过分析嵌入式操作系统的启动装载原理,提出一种基于BF531DSP的无操作系统数字存储示波器的启动加载程序设计,以ADI公司的BF531为核心,控制Flash,SDRAM等硬件的初始化并控制SL811从USB中读写更新文件。实验结果表明,该设计能实现系统正常模式启动装载和在线升级功能,且操作简单,执行效率高。

| Abstract: | Bootloader,which is used to load programs into on-chip ROM and startup system at the same time,is an indispensable part of system procedures.After analyzing the principle of bootloader in embedded operating system,the author had designed a bootloader based on BF531 DSP for a digital storage oscilloscope without operating system.The design used ADI BF531 as the core,controlled the initialization of Flash,SDRAM and other hardware,and controlled SL811 to read/write updating files from USB.The experimental resu... |
