根文件系统烧进去了
我本来设置的Kernel cmd line是下面这个
Kernel command line: noinitrd root=/dev/bon/3 init=/linuxrc console=ttySAC0 cons

这样也会出错，然后我把它改成了noinitrd root=/dev/mtdblock3 init=/linuxrc console=ttySAC0 跟内核的那个kernel boot string设置成一样的然后就出了上面的错，第一次的错误如下

vivi>　　　　　　

不知道你那个内核的驱动里是不是mtdblock3哦　　　　　　

看你的出错信息 应该是内核没找到根文件系统  

你在vivi中把根文件系统设置成 root=/dev/bon/3 或者 root=/dev/mtdblock3   这可不是乱设置的  这是根据做的根文件系统里的 /dev 下面的设备节点来设置的 (当然也和你内核里的MTD相联系) 看你根文件系统下的mtdblockN(N=0,1,2...) 建了没

看你这个错误 :VFS: Cannot open root device "bon/3" or unknown-block(2,0)
说明 /dev 下面没bon/3   

再看你这个错误:No filesystem could mount root, tried:  cramfs romfs
说明内核到/dev/mtdblock3 找根文件系统了 只不过没找到  所以报错.这错误还给我们一个信息,那就是flash是以块设备的形式(mtdblock)组织的

我们可以用个苯点的法子来解决这个问题: 在vivi下设置启动参数时 其中的 root=/dev/mtdblock3 把3改为 1 2 4 5 6 一个一个来试.

顺便说一句

我们开始的时候最后通过网络挂根文件系统的方式来调板子和程序.

你的MTD分区名字最好能重新命名一下  方便调试 呵呵

晕，咋不像是在你那个分区上哦？　　　　　　

我也觉得是内核里的Flash分区没有生效，我再重新编译一个内核试试
谢谢版主！！

在/arch/arm/match-s3c2410/devs.c中添加的内核分区没有生效。

2.
vivi中的linux_cmd_line设置改为
noinitrd root=/dev/mtdblock3 init=/linuxrc console=ttySAC0



修改了内核MTD分区后，内核可以启动，根文件系统算是挂载上并且可以进入Shell
但是根文件系统还有些问题
我参考的这篇文章做得
///////////////////////////////////////////////////////////////////////////////////////////////////////
1. busybox的编译

-----------------------------------------------------------------------------
一 修改busybox中的 Makefile文件
找到 ARCH 和 CROSS_COMPILE 修改成如下
ARCH               ?= arm
CROSS_COMPILE      ?= /usr/local/arm/3.3.2/bin/arm-linux-

二 配置

[root@localhost busybox-1.4.2]# make defconfig
[root@localhost busybox-1.4.2]# make xconfig
=============================================
修改配置 主要修改如下
=============================================
Busybox Settings
        Build Options
      

Build BusyBox as a static binary   
         //选此项静态编译。

Miscellaneous Utilities
        []taskset       //选了就会出错

-------------------------------------------------
三 编译
[root@localhost busybox-1.5.1]# make all install
-----------------------------------------------------------------
最后会在 busybox-1.5.1/_install/目录生成你要的 bin sbin usr 目录
------------------------------------------------------------------

2. 编写linuxrc 文件
-----------------------------------------------------------------
#!/bin/sh
#echo "mount /etc as ramfs"
/bin/mount -n -t ramfs ramfs /etc
/bin/cp -a /mnt/etc/* /etc

echo "re-create the /etc/mtab entries"
# re-create the /etc/mtab entries
/bin/mount -f -t cramfs -o remount,ro /dev/mtdblock/3 /

#mount some file system
echo "mount /dev/shm as tmpfs"
/bin/mount -n -t tmpfs tmpfs /dev/shm


#挂载/proc为proc文件系统
echo "mount /proc as proc"
/bin/mount -n -t proc none /proc

#挂载/sys为sysfs文件系统
echo "mount /sys as sysfs"
/bin/mount -n -t sysfs none /sys

/bin/mount -f -t ramfs ramfs /etc

echo "yaffs is mounted"
/bin/mount -t yaffs /dev/mtdblock/1 /mnt/yaffs
exec /sbin/init
---------------------------------------------------------------------
3. 权限修改
chmod chmod 775 linuxrc

4. 编写 inittab文件

---------------------------------------------------------------------
::sysinit:/etc/init.d/rc

::askfirst:-/bin/sh
tty2::askfirst:-/bin/sh
tty3::askfirst:-/bin/sh
tty4::askfirst:-/bin/sh
tty0::askfirst:-/bin/sh
   
::restart:/sbin/init
        
::ctrlaltdel:/sbin/reboot
::shutdown:/bin/umount -a -r
::shutdown:/sbin/swapoff -a
----------------------------------------------------------------------

5. rc文件
----------------------------------------------------------------------
#!/bin/sh

/bin/mount -a
-----------------------------------------------------------------------

6. fastab 文件
----------------------------------------------------------------------
none      /proc      proc defaults 0 0
none      /dev/pts devpts mode=0622 0 0
tmpfs      /dev/shm tmpfs defaults 0 0
----------------------------------------------------------------------


7. 各文件的关系
----------------------------------------------------------------------
7.1 建立一个目标板的空根目录
我们将在这里构建构建根文件系统，创建基础目录结构. 存放交叉编译后生成的目标应用程序
（BUSYBOX，TINYLOGIN），存放库文件等。
[root@localhost rootfs]# mkdir my_rootfs
[root@localhost rootfs]# pwd
/home/arm/dev_home/rootfs/my_rootfs
[root@localhost rootfs]# cd my_rootfs
[root@localhost my_rootfs]#
7.2 在my_rootfs中建立Linux目录树
[root@localhost my_rootfs]#mkdir bin dev etc home lib mnt proc sbin sys tmp root usr
[root@localhost my_rootfs]#mkdir mnt/etc
[root@localhost my_rootfs]#mkdir usr/bin usr/lib usr/sbin
[root@localhost my_rootfs]#touch linuxrc
[root@localhost my_rootfs]#tree
|bin
|dev
|etc
|home
|lib
|linuxrc
/* 此文件为启动脚本，是一shell脚本文件。本文后面有专门介绍 */
|mnt
| `etc   
|proc
|sbin
|sys
|tmp
|root
`usr
|bin
|lib
`sbin

8. 把上面编译出来的 busybox文件拷贝到 my_rootfs 文件系统

---------------------------------------------------------------
把 busybox1.5.1/_install/目录下的 bin sbin usr 覆盖 my_rootfs
文件夹里的空文件夹。
--------------------------------------------------------------

9. 把 5 生成的文件(rc)拷贝到 /mnt/etc/init.d/目录（先在/mnt/etc/目录新建格init.d目录）
把 4，6生成的文件（inittab和 fastab ）放到 /mnt/etc/目录
把 2 生成的文件linuxrc 放到/目录
            这里所提到的 /目录即my_rootfs目录。
10. 新建/dev设备,在/dev目录（即my_rootfs/dev/）.
mknod console c 5 1

8. 生成cramfs文件

----------------------------------------------------------------
下载mkfs.cramfs工具，然后用下面命令生成你要的cramfs文件系统
./mkfs.cramfs ./my_rootfs       ./root.cramfs

//////////////////////////////////////////////////////////////////////////////////////////////
挂载后的结果是

请版主指点一下应该修改，或增加那些东西 我的内核是2.6.18.3的。　　　　　　

dev下的设备文件还是没有建全吧　　　　　　

我 配置 了 devfs，设备 结点应该自动建立
