Uboot_tiny6410

移植u-boot-2010.09到Tiny6410开发板

Hyz

一、开发环境

Fedora13、tiny6410开发板

二、u-boot

1.版本：u-boot-2010.09

2.下载地址：www.denx.de/pub/u-boot/

三、移植

(一)首先需建立交叉编译环境

1.将光盘Linux 目录中的arm-linux-gcc-4.5.1-v6-vfp-20101103.tgz 复制到Fedora9 某个目录下如tmp/，然后进入到该目录，执行解压命令：

#cd /tmp

#tar xvzf arm-linux-gcc-4.5.1-v6-vfp-20101103.tgz –C /

注意：C 后面有个空格，并且C 是大写的，它是英文单词“Change”的第一个字母，

在此是改变目录的意思。

如果你没有arm-linux-gcc-4.5.1-v6-vfp-20101103.tgz请到我的QQ空间下载。

执行该命令，将把 arm-linux-gcc 安装到/opt/FriendlyARM/toolschain/4.5.1 目录。

2.把编译器路径加入系统环境变量，运行命令

#gedit /root/.bashrc

编辑/root/.bashrc 文件，注意“bashrc”前面有一个“.”，修改最后一行为export PATH=$PATH: /opt/FriendlyARM/toolschain/4.5.1/bin，注意路径一定要写对，否则将不会有

效。

如图，保存退出。

重新登录系统(不必重启机器，开始->logout 即可)，使以上设置生效，在命令行输入arm-linux-gcc –v，会出现如下信息，这说明交叉编译环境已经成功安装。

(二)解压安装源代码

1.首先创建工作目录

工作目录/opt/FriendlyARM/tiny6410/linux

执行命令：#mkdir –p /opt/FriendlyARM/mini6410/linux

2.将源代码放到linux系统下（使用sharefoder等）

如：放到/mnt/hgfs/share下

3.解压安装u-boot源代码

在工作目录/opt/FriendlyARM/mini6410/linux 中执行：

#cd /opt/FriendlyARM/tiny6410/linux

#tar xvzf /mnt/hgfs/share/u-boot-2010.09.tar.gz

会自动生成u-boot-2010.09文件夹

(三)对u-boot-2010.09源代码进行修改

1.打开顶层目录下的Makefile，并在ARM1176处添加下面红色部分内容
