制作文件系统
编译步骤省略

# mkdir lib etc proc tmp sys# arm-linux-strip *.so

# vi etc/inittab::sysinit:/etc/init.d/rcS ::askfirst:-/bin/sh::ctrlaltdel:/sbin/reboot::shutdown:/bin/umount -a –r::restart:/sbin/init

注：/bin/sh前须要添加前缀“-”，否则会提示以下错误：

/bin/sh: can't access tty; job control turned off 

# mkdir etc/init.d# vi etc/init.d/rcSmount -t tmpfs mdev /dev    mkdir /dev/pts  mount -a  echo /sbin/mdev > /proc/sys/kernel/hotplug  mdev -s  exec /usr/local/rc.local# chmod +x rcS

rc.local 是默认启动的最后一个脚本文件

# vi usr/local/rc.local#!/bin/shinsmod led.ko/home/led_app
