[Yaffs] Yaffs2 and nandsim problem

<-- Warning: charset 'ks_c_5601-1987' is not supported -->

Hello!

My system-----------------------------------
OS: Fedora Core 6
kernel version: 2.6.18.1 (recompile)
MTD: Embedded mtd in the kernel
Yaffs: yaffs_fs.c,v 1.56 2007/01/19 04:07:48
--------------------------------------------

I want to use yaffs2 with nandsim(in mtd) that have a 2048 page.
I load module nandsim after the nandsim build. So, I saw the aleph1 site.
# modprobe nandsim first_id_byte=0x20 second_id_byte=0xa2
third_id_byte=00 fourth_id_byte=0x15

I can find error messages(too many) by dmesg command.
Almost message is cut because buffer size.
I copy some of error messages. (Below)

But nandsim module is loaded.
I mount yaffs2
# mount /dev/mtdblock1 test_dir -t yaffs2
# cd test_dir
# touch testtile
But Memory isn't allocated to create file.

Why can I don't load nandsim module?
Perhaps, is not support(or not perfectly support) MTD and nandsim for nand
flash with pages of 2048 bytes?

I want to your answer or hint, please.
Thank you.
