Hi, my friends:

I make yaffs image by mkyaffs2image.

There is only file 05.mp3 in 05.yaffs.

When I mount the partition, the file size is wrong.

but when I test some small size file(5095 Bytes), it can work.

I use mkyaffs2image.c version r1.4 2007-02-14.

my nand flash pagesize is 2KB, oob is 64 B.

If I make a larger yaffs image (6,363,456 bytes),  the situation is worst.

There are lost some files and some file size is wrong.

BTW: copy a file into yaffs partition is OK.

Any suggestition for me?

Thanks a lots.


underneath is my log:
