busybox制作文件系统 no init found panic解决办法

busybox制作文件系统 no init found panic
使用busybox制作文件系统。
首先使用脚本建立rootfs根文件系统如下

JScript code

echo "making dir:bin dev etc lib proc sbin sys usr gui flash"mkdir bin dev etc lib proc sbin sys usr gui flash mnt varmkdir usr/bin usr/lib usr/sbin lib/modulesmknod -m 600 dev/console c 5 1mknod -m 666 dev/null c 1 3echo "making dir:mnt tmp var"mkdir mnt/etc mnt/jffs2 mnt/yaffs mnt/data mnt/tempmkdir var/lib var/lock var/log var/run var/tmpchmod 1777 var/tmpecho "making dir:home root boot"mkdir home root bootecho "done"

然后在init.d/rcS中编译：
#!/bin/sh

# Start all init scripts in /etc/init.d
# executing them in numerical order.
mount -t proc proc /proc
mount -a
echo hello

使用mkfs.jffs2制作jffs2文件系统：
cd rootfs
chmod +x etc/init.d/rcS
cd ../
mkfs.jffs2 -e 0x10000 --pad=0x200000 -l -d rootfs -o jffs2.bin

file mkfs.jffs2显示：
mkfs.jffs2: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, not stripped

将jffs2.bin使用jtag烧写到nor flash后，通过uboot引导启动，但是显示pannic

然后一直打印以下内容：

这是哪里有问题，

[解决办法]
Kernel command line: init=/linuxrc rootfstype=jffs2 root=/dev/mtdblock2 rw console=ttyS0,115200 mem=32M
Kernel panic - not syncing: No init found. Try passing init= option to kernel. 

你bootargs中指定的 init=/linuxrc 系统没找到， 你在rootfs文件夹下看生成linuxrc了没。
有些是不用linuxrc的，换成其他的.

另，很多步骤可能出错的. 不如你jffs2的大小，系统的大小端等等.

LZ看看一个个排除下吧。

最后，那个生成的jffs2是Intel 80386的？？？？？ 
我file了我生成的jffs2，提示说是 data （我的jffs2不做根文件系统）.
没file过jffs2 不知道你这个80386的bin对不对.... 
还有那个busybox，我咋没见到它的身影捏...
