help:yaffs partition can't mount, no such file, with detailed problem description

["frankxu0217" <frankxu0217@xxxxxxxxxxxx>]

Hello,all,

I'm now using an s3c2410-based board, with 64MB nand flash and 64MB SDRam. And now the 2.4.18 kernel and the cramfs file system works!
But the yaffs partition in my fstab can't mount while initialing system, the detailed problem description attaches below:

The bootloader -vivi partitions：
vivi> part show
mtdpart info. (5 partitions)
name offset size flag
------------------------------------------------
vivi : 0x00000000 0x00020000 0 128k
param : 0x00020000 0x00010000 0 64k
kernel : 0x00030000 0x00800000 0 8M
root : 0x00830000 0x00400000 4 4M
usr : 0x00c30000 0x033d0000 4 51M+832k 
Referring to some online documents, I have made a self-defined file system my_rootfs:

the busybox version is 1.1.3, linuxrc is linked to busybox, and below are some init scripts:

finally I made them to a cramfs filesystem root.cramfs, download it to root partition in vivi:
[root@redhatel3 root]# mkcramfs my_rootfs root.cramfs 
here is my boot information：

Thank you for taking so much time to read above descriptions, now my questions:
1/ I have made the yaffs support in the kernel, why is there no corresponding information in the booting information?
1/ how can I format my /dev/mtdblock/4 in rootfs or usr/ in vivito to yaffs format? 
3/ when mounting the /dev/mtdblock/4, why is it saying "no such file or directry"?
4/ there is a lost+found directry in the /mnt/usr, after a "umount", then the directry has nothing, what does that mean?
Thanks again！
