TP-LINK TL-WR703N OpenWRT 12.09 从U盘启动
先把固件弄到12.09，12.09的地址在这http://downloads.openwrt.org/attitude_adjustment/12.09/ar71xx/generic/
cd /tmp wget http://downloads.openwrt.org/attitude_adjustment/12.09/ar71xx/generic/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-sysupgrade.bin sysupgrade openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-sysupgrade.bin
重新启动之后，安装相关的软件包(我的是ext4的U盘，并且对应/dev/sda)
opkg update opkg install kmod-usb-ohci kmod-usb2 kmod-fs-ext4 kmod-usb-storage # 如果找不到U盘的话reboot一下
mkdir /tmp/root #创建/挂载点 mount -o bind / /tmp/root/ # 挂/ cp /tmp/root/* /tmp/u -a # 将系统备份到U盘 echo "--booted from flash--" >> /etc/banner # 设置内部启动标识 echo "--booted from u disk--" >> /tmp/u/etc/banner # 设置U盘启动标识 umount /tmp/u # 卸载U盘 umount /tmp/root/ # 卸载/ opkg update # 更新软件源 opkg install block-mount # 安装 block-mount
vi修改/etc/config/fstab文件为如下mount内容：
config mount
# option target /home
option device /dev/sda
option fstype ext4
option options rw,sync
option enabled 1
option enabled_fsck 1
option is_rootfs 1
成功的话启动你能看到：
