AT91sam9260ek开发板linux编译

1.VMware下ubuntu12.04开发环境搭建

3、源列表更新
建议使用网易源，比较稳定速度也比较快，更新源的方法如下：
root@ubuntu:/# cd /etc/apt/
备份之前的源列表文件，并创建新的源列表文件 sources.list
root@ubuntu:/# vi sources.list
在打开的文件中输入以下列表：
deb http://mirrors.163.com/ubuntu/ precise main restricted
deb-src http://mirrors.163.com/ubuntu/ precise main restricted
deb http://mirrors.163.com/ubuntu/ precise-updates main restricted
deb-src http://mirrors.163.com/ubuntu/ precise-updates main restricted
deb http://mirrors.163.com/ubuntu/ precise universe
deb-src http://mirrors.163.com/ubuntu/ precise universe
deb http://mirrors.163.com/ubuntu/ precise-updates universe
deb-src http://mirrors.163.com/ubuntu/ precise-updates universe
deb http://mirrors.163.com/ubuntu/ precise multiverse
deb-src http://mirrors.163.com/ubuntu/ precise multiverse
deb http://mirrors.163.com/ubuntu/ precise-updates multiverse
deb-src http://mirrors.163.com/ubuntu/ precise-updates multiverse
deb http://mirrors.163.com/ubuntu/ precise-backports main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ precise-backports main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ precise-security main restricted
deb-src http://mirrors.163.com/ubuntu/ precise-security main restricted
deb http://mirrors.163.com/ubuntu/ precise-security universe
deb-src http://mirrors.163.com/ubuntu/ precise-security universe
deb http://mirrors.163.com/ubuntu/ precise-security multiverse
deb-src http://mirrors.163.com/ubuntu/ precise-security multiverse
deb http://extras.ubuntu.com/ubuntu precise main
deb-src http://extras.ubuntu.com/ubuntu precise main
保存之后退出，用如下命令更新源列表：
root@ubuntu:/# sudo apt-get update
3、更新成功之后就可以进行软件的安装了，以下安装一些常用必备的软件：
root@ubuntu:/# apt-get install build-essential
root@ubuntu:/# apt-get install libncurses5-dev
root@ubuntu:/# apt-get install bison
root@ubuntu:/# apt-get install flex
root@ubuntu:/# apt-get install gettext
root@ubuntu:/# apt-get install texinfo
root@ubuntu:/# apt-get install subversion
（注意：更改sourse.list后需要重启）

 2.安装gcc4.3.2

解压gcc4.3.2，并安装到路径/usr/local/arm/4.3.2/lib/arm-none-linux-gnueabi

3.bootstrap编译

1、vi ~/.bashrc  修改环境变量    在其最后一行加上export PATH=usr/local/arm/4.3.2/bin:$PATH       source ~/.bashrc使其生效 2.进去工作页面 3.修改makefile ifndef ERASE_FCT
ERASE_FCT=rm -f
endif
ifndef CROSS_COMPILE
CROSS_COMPILE=arm-linux-
endif


TOOLCHAIN=gcc


BOOTSTRAP_PATH=../../.. 然后make就可以

4.uboot编译

make clean 

make at91sam9260ek-config make 就可以编译

5.内核编译

make uImage ubuntu@ubuntu:~/work9260/linux-2.6-1/linux-2.6.30/arch/arm/boot$ 
会在以上目录生成所需要的uImage文件 如果遇到的问题：/bin/sh :1:lzop:not found 解决方式：sudo apt-get install lzop

6.文件系统编译

1.解压：gunzip ramdisk.gz 2.镜像文件挂载 mount -o loop /hpme/..../ramdisk  /mnt/loop 3.cd /mnt/loop 4.修改完以后卸载文件系统：跳到/mnt/loop 目录外  umount /mnt/loop 5.压缩gzip -V9 ramdisk

7.应用程序编译 

makefile：1.工具路径修改 2.ADDEDLIBS = -lpthread -lcommon.....          是整个app中编一个 3.chmod +x yaffs zimage使其具有可执行权限
