VFS: Mounted root (yaffs filesystem).
Mounted devfs on /dev
从这两句可以看出，文件系统已经可以工作了，但是没有busybox的信息，说明busybox没有工作或者工作量串口没有输出
尝试修改etc/inittab 的s3c2410_serial0为ttyS0或ttySAC0均无效
#etc/inittab
::sysinit:/etc/init.d/rcS
s3c2410_serial0::askfirst:-/bin/sh
::ctrlaltdel:/sbin/reboot
::shutdown:/bin/umount -a -r
参考http://www.cnblogs.com/leaven/archive/2010/10/09/1846809.html
串口输出内容如下：yaffs: dev is 32505859 name is "mtdblock3"
yaffs: passed flags ""
yaffs: Attempting MTD mount on 31.3, "mtdblock3"
yaffs_read_super: isCheckpointed 0

原因一:
内核与文件系统中的busybox不是同一个版本的编译器编译出来的。在内核启动的过程中，会有如下打印信息，从中可以确认
是当前编译的内核：
Linux version 2.6.25.20 (root@ubuntu) (gcc version 4.3.3 (Sourcery G++ Lite 2009q1-203) ) #5 Tue Oct 12 17:05:52 CST 2010
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
原因二
是busybox编译为armv6架构的，所以不能执行。
另外，在/etc/inittab文件中通过::respawn:-/bin/login 登录控制台，而密码文件/etc/passwd由于是从主机中拷贝过来的其内容为：
root:x:0:0:root:/root:/bin/bash
修改为：
root:x:0:0:root:/root:/bin/ash 或者 root:x:0:0:root:/root:/bin/sh
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
原因三
编译器编译出来的busybox配对使用的内核版本最好要与实际内核版本配对

这个busybox1.2.0用gcc4.3.2编译的，用3.4.1编译出来是这样
