[Yaffs] yaffs2 utilites and testing?

Hi everyone,

I am wondering if I could get a utilities for yaffs2 filesystem testing.
The flash I have is 256 MB Samsung, 8 bit. and the board is arm9.
Is the following order right?
Generating image, pushing it to flash, mounting mtdblock as yaffs2 on a directory, running test cases in the mounted directory?

Any information of mounting and testing would be great.

Thanks,

Pradeep
