Uboot_for_Tiny6410_移植步骤详解一、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NAND FLASH启动二、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：128M DDR RAM，可升级至256M；MLC NAND Flash(2GB)3)其他资源：具有三LCD接口、4线电阻触摸屏接口、100M 标准网络接口、标准DB9 五线串口、Mini USB 2.0 接口、USB Host 1.1、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SD WiFi)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.tgz三、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。
