文件系统挂载问题。

15# embedsky_lxt

版主啊，那个选项没起作用额，还是不行。
你看看我 u-boot里面的设置对不对呢？
baudrate=115200
ethaddr=0a:1b:2c:3d:4e:5f
mtdids=nand0=nandflash0
filesize=1063a40
filesize+1=1080000

netmask=255.255.255.0
ipaddr=192.168.1.230
serverip=192.168.1.100
bootargs=noinitrd root=/dev/mtdblock2 init=/linuxrc console=ttySAC0 rootfstype=yaffs
bootdelay=3
bootcmd=nand read 30008000 100000 300000;bootm 30008000
mtdparts=nandflash0:512k@0(bios),128k(params),384k(toc),3m(kernel),-(root)
stdin=serial
stdout=serial
stderr=serial

Environment size: 455/131068 bytes

mtdparts 这个变量我改过，不晓得对不对，

我说一下我的制作内核的过程：
进入解压后的目录（我的是linux-2.6.30）
make menuconfig－>make zImage->cp arch/arm/boot/zImage ./ —>
mkimage -A arm -O linux -T kernel -C none -a 30008000 -e 30008040 -n linux-2.6.30 -d zImage uImage.img
－>通过uboot的tftp下载uImage.img 到内存30008000处－>bootm 30008000
然后就打印出（前面的打印信息略过）：（文件系统已经在mtdblock2上）

先向各位版主问好。
这是挂载文件系统后的打印信息，里面增加的文件都是照手册上copy下来的，不晓得为什么会出现这样的错误。。。。

弄好了！原来是要在dev目录下创建块设备的节点

brw-rw----    1 0        0         31,   2 Jan  1 00:00 mtdblock2

但是现在又有一个新问题：第次开机启动的时候都打印这个，而且一次比一次多！
Partially written block 116 detected

我的也出现这个问题。。
我的串口是打印：

分区是这样的：

0x000000000000-0x000000040000 : "uboot"

0x000000500000-0x000010000000 : "yaffs2"

dev目录下面我创建了 console字符设备和null设备。。
问一下我的有什么问题吗？

LZ你的是发现了坏块。。

21# zengraoli


还要在dev目录下面创建nand的分区结点.

创建三个块设备

23# vip2009


好的 我试试。。不行再来问一下！

我的还是不行啊。。
不知道我设备创建对不对?
我这样创建的。。

然后启动之后 串口还是会

19# vip2009
设备节点的创建，自然有驱动来完成，如果你这些节点没有完成，我怀疑是nand的驱动方面的问题

26# shufexiu


那我的又是怎么回事呢？怎么总是挂载不成功？我只是在制作文件系统啊？内核用的是光盘自带的，u-boot也是的。。

27# zengraoli


你怎么烧的文件系统？

28# vip2009


在U-boot按6 通过DNW烧啊？不对吗？

我不知道那个6号键是将文件系统烧到什么地方去了，有可能没有在你的文件系统的分区里面，我个我是猜的哈，你可以用nand write试试;
我是在uboot启动后按两次"q"后通过tftp 把文件系统下载到内存，然后用nand erase擦除，nand write.yaffs 写到nand的第三个分区上的。
