Uboot_for_Tiny6410_移植步骤详解

Uboot_for_Tiny6410_移植步骤详解1、 设计 领导形象设计圆作业设计ao工艺污水处理厂设计附属工程施工组织设计清扫机器人结构设计 要求1.目的1)掌握U-boot剪裁编写2)掌握交叉编译环境的配置3)掌握U-boot的移植2.实现的功能1)U-boot编译成功2)移植U-boot，使系统支持从NANDFLASH启动2、设计方案1.硬件资源1)ARM处理器：ARM11芯片(SamsungS3C6410A)，基于ARM1176JZF-S核设计，运行频率533Mhz,最高可达667Mhz2)存储器：128MDDRRAM，可升级至256M；MLCNANDFlash(2GB)3)其他资源：具有三LCD接口、4线电阻触摸屏接口、100M 标准 excel标准偏差excel标准偏差函数exl标准差函数国标检验抽样标准表免费下载红头文件格式标准下载 网络接口、标准DB9五线串口、MiniUSB2.0接口、USBHost1.1、3.5mm音频输入输出口、标准TV-OUT接口、SD卡座、红外接收等常用接口；另外还引出4路TTL串口，另1路TV-OUT、SDIO2接口(可接SDWiFi)接口等；在板的还有蜂鸣器、I2C-EEPROM、备份电池、AD可调电阻、8个中断式按键等。2.软件资源1)arm-linux-gcc-4.5.1（交叉编译）2)u-boot-2010.09.tar.gzarm-linux-gcc-4.5.1-v6-vfp-20101103.tgz3、移植过程1.环境搭建1)建立交叉编译环境2)去这2个网站随便下载都可以下载得到最新或者你想要的u-boot。（http://www.icdev.com.cn/batch.viewlink.php?itemid=1694ftp://ftp.denx.de/pub/u-boot/）下面是具体的对u-boot…的修改一：下载并解压u-boot-gxb.tar.gz。
