二、配置tftp
#setup 选择系统服务，把tftp选项打*
#vim /etc/xinetd.d/tftp
disable = no
#service xinetd restart
把zImage拷贝到/tftpboot下
三、给SD卡分区
1.把SD卡插入PC机
2.卸载SD卡
fdisk -l 查看SD卡对应的设备
umount /dev/sdb1 卸载掉SD卡的分区
3.删除SD卡原有分区并建立新的分区
fdisk /dev/sdb 给SD卡创建分区表
zhiyongli@LZY:~ fdisk /dev/sdb
You will not be able to write the partition table.
Command (m for help): m 查看帮助
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
l list known partition types
m print this menu
n add a new partition
o create a new empty DOS partition table
p print the partition table
q quit without saving changes
s create a new empty Sun disklabel
t change a partition's system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)
Command (m for help): p 打印分区表

Command (m for help)：q 退出
4.挂载分区2并写入跟文件系统
root@LZY:~# mkfs.ext3 /dev/sdb2
root@LZY:~# mount /dev/sdb2 /mnt/
root@LZY:/home/zhiyongli/smdk6410_lzy/rootfs# tar -xvf rootfs.tar -C /mnt/
root@LZY:~# umont /dev/sdb2
三、烧写sd卡u-boot
主机：
#./write_sd /dev/sdb u-boot-movi.bin
四、配置主机IP和开发板IP
开发板：
[u-boot-sd]# set serverip 192.168.1.10
[u-boot-sd]# set ipaddr 192.168.1.20
[u-boot-sd]# save
五、下载并烧写内核到SD卡
[u-boot-sd]# tftp 50000000 zImage
[u-boot-sd]# movi write kernel 50000000
六、设置自动启动和挂载跟文件系统
[u-boot-sd]# set bootargs “noinitrd root=179:2 rw console=ttySAC0,115200”
[u-boot-sd]# set bootcmd “movi read kernel 50008000;bootm 50008000”
[u-boot-sd]# save
[u-boot-sd]# reset
七、启动根文件后, 使用nfs 挂载主机上的工作目录
mount -t nfs -o intr,nolock 192.168.1.10:/nfsroot /mnt
