1. 下载最新的版本为busybox-1.20.0
2. 修改busybox的makefile：

   CROSS_COMPILE ?= arm-linux-

   ARCH ?= arm

3. Make menuconfig配置busybox

   Busybox Settings --->

   Build Options --->

   

   Installation Options ("make install" behavior) --->

   

   Busybox Library Tuning --->

   

4. 编译busybox执行

   Make install

   这时候会提示一个错误提示说：

   miscutils/ubi_tools.c:63:26: error: mtd/ubi-user.h: No such file or directory
   miscutils/ubi_tools.c: In function 'ubi_tools_main':
   miscutils/ubi_tools.c:133: error: 'UBI_DEV_NUM_AUTO' undeclared (first use in this function)
   miscutils/ubi_tools.c:133: error: (Each undeclared identifier is reported only once
   miscutils/ubi_tools.c:133: error: for each function it appears in.)
   miscutils/ubi_tools.c:134: error: 'UBI_VOL_NUM_AUTO' undeclared (first use in this function)
   miscutils/ubi_tools.c:153: error: storage size of 'req' isn't known
   miscutils/ubi_tools.c:161: error: 'UBI_IOCATT' undeclared (first use in this function)
   miscutils/ubi_tools.c:153: warning: unused variable 'req'

make[1]: *** [miscutils/ubi_tools.o] 错误 1
make: *** [miscutils] 错误 2

出现这么多的错误，核心问题就是出现在miscutils/ubi_tools.c:63:26: error: mtd/ubi-user.h: No such file or directory这个上面，无法找到mtd/ubi-user.h头文件，查阅了相关资料后，原来这是一个Linux下新支持的UBI文件系统，需要手 工加入。从Linux3.3.5的include\mtd\ubi-user.h拷贝到busybox下的include\mtd下，如果 busybox下的include没有mtd文件夹，那就先建立一个mtd文件夹，然后复制了。这样做了之后，编译就OK了。出现下面的信息就说明编译成 功了。

1. 建立根目录，这里我们直接写一个脚本程序运create_rootfs.sh行就可以了,脚本的内容如下：

   #!/bin/sh
   echo "------Create rootfs directons start...--------"
   mkdir rootfs
   cd rootfs
   echo "--------Create root,dev....----------"
   mkdir root dev etc boot tmp var sys proc lib mnt home usr
   mkdir etc/init.d etc/rc.d etc/sysconfig
   mkdir usr/sbin usr/bin usr/lib usr/modules
   echo "make node in dev/console dev/null"
   mknod -m 600 dev/console c 5 1
   mknod -m 600 dev/null c 1 3
   mkdir mnt/etc mnt/jffs2 mnt/yaffs mnt/data mnt/temp
   mkdir var/lib var/lock var/run var/tmp
   chmod 777 tmp
   chmod 777 var/tmp
   echo "-------make direction done---------"

   运行脚本执行：

   ./ create_rootfs.sh

   ls rootfs

   boot dev etc home lib mnt proc root sys tmp usr var

2. etc/inittab 系统init进程配置文件，并更改权限 chmod +x inittab

   ::sysinit:/etc/init.d/rcS
   ::askfirst:-/bin/sh #没有这就不行，就不能打开console控制台。
   ::restart:/sbin/init
   ::ctrlaltdel:/sbin/reboot
   ::shutdown:/bin/umount -a -r
   ::shutdown:/sbin/swapoff –a

3. etc/init.d/rcS系统启动加载项文件，并更改权限chmod +x etc/init.d/rcS

   #!/bin/sh
   PATH=/sbin:/bin:/usr/sbin:/usr/bin
   runlevel=S
   prevlevel=N
   umask 022
   export PATH runlevel prevlevel
   mount -a
   mkdir /dev/pts
   mount -t devpts devpts /dev/pts #用于telnet登录时使用

   echo /sbin/mdev > /proc/sys/kernel/hotplug
   mdev -s
   mkdir -p /var/lock
   /bin/hostname -F /etc/sysconfig/HOSTNAME

4. etc/fstab 系统挂载文件系统列表文件

   #device mount-point type option dump fsck order
   proc /proc proc defaults 0 0
   sysfs /sys sysfs defaults 0 0
   mdev /dev ramfs defaults 0 0
   none /var ramfs defaults 0 0
   none /tmp ramfs defaults 0 0

5. etc/profile用户环境配置文件

   # Ash profile
   # vim: syntax= sh
   # No core file by defaults
   # ulimit - S - c 0> / dev/ null 2> & 1

   USER="id -un"
   LOGNAME=$USER
   PS1="[\u@\h \w]#" #\w 目录将显示全路径
   PATH=$PATH
   HOSTNAME= '/bin/hostname'
   alias cls="clear"
   export USER LOGNAME PS1 PATH

6. /etc/passwd shadow 用户文件以及密码

   把主机的passwd shadow 文件拷贝到/etc下

   # cp /etc/passwd rootfs/etc
   # cp /etc/group rootfs/etc
   # cp /etc/shadow rootfs/etc

7. etc/sysconfig/HOSTNAME的内容为你自己的名字即可,内容为"Pillar"

   gedit /etc/sysconfig/HOSTNAME 然后键入 Pillar

8. 在busybox目录下会看见 _install目录，里面有/bin /sbin l inuxr三个文件
   将这三个目录或文件拷到第一步所建的rootfs文件夹下。

   #cp bin/ sbin/ linuxrc /home/rootfs -ra

   在把_install目录的usr里面的bin,sbin也按照刚才的方法拷贝到rootfs目录下

   切记一定要带上-a的参数，因为bin目录里大部分都是链接，如果不带-a的参数，拷过去之后会做相应的复制，不再是链接的形式

   将交叉编译器下的lib下的库拷贝到lib文件夹下
   cp /usr/local/arm/4.2.2-eabi/lib/* ./

9. 这时候rootfs目录下的tree应该是这个样子的：

10. 修改uboot的bootargs为下面内容：

    setenv bootargs noinitrd root=/dev/nfs ip=192.168.1.104:192.168.1.103:192.168.1.1:255.255.255.0::eth0:off nfsroot=192.168.1.103:/home/superzuo/rootfs,nolock,proto=tcp consloe=ttySAC0,115200

    其中192.168.1.104为开发板的IP地址（用print命令可以查看）

    192.168.1.103为虚拟机的IP地址

    192.168.1.1为路由器的网关，在电脑上可以用ipconfig /all命令查看

    255.255.255.0为子网掩码，在电脑上可以用ipconfig /all命令查看

    先备份一下之前用yaffs2的启动

    noinitrd root=/dev/mtdblock3 rootfstype=yaffs2 console=ttySAC0 init=/linuxrc video=fb:AT070TN83

11. 使开发板支持域名解析：

1. 配置内核：

   [*] Networking support --->

   

   File systems --->

   [*] Network File Systems --->

   

2. 启动开发板就可以看见一下信息：

   Registering the dns_resolver key type

   VFP support v0.3: implementor 41 architecture 1 part 20 variant b rev 5

   input: gpio-keys as /devices/platform/gpio-keys/input/input0

   s3c-rtc s3c64xx-rtc: setting system clock to 2000-07-27 09:18:46 UTC (964689526)

   dm9000 dm9000.0: eth0: link down

   IP-Config: Complete:

   host=192.168.1.104, domain=, nis-domain=(none),

   bootserver=192.168.103.0, rootserver=192.168.1.103, rootpath=

   VFS: Mounted root (nfs filesystem) on device 0:10.

   Please press Enter to activate this console.

   Pillar

   [root@Pillar /]#ls

   bin dev home linuxrc proc sbin tmp var

   boot etc lib mnt root sys usr

   这说明NFS已经完全挂载上了，这比飞凌官网提供的系统好多了，我这里文件系统支持文件路径显示和主机信息显示。

   在启动的过程中可能 会碰到一个问题：

   Starting pid 768, console /dev/console: '/etc/init.d/rcS' （这个错误就在启动信息的最后一行一定要注意）

   解决的方法是在主机给rcS修改权限：

   chmod -R 777 init.d/*

   最后来一个启动信息最后的截图：
