Thanks for the patch. It did not work for me though. My current solution is to make a standard
ext2 fs image, mount it in loopback mode and copy the image to a mounted NAND-yaffs2 directory:

1. eraseall /dev/mtdN
2. mount -t yaffs2 /dev/mtdblockN /dest/dir
3. mount -t ext2 -o loopback ext2_image /source/dir
4. cp source to dest

This is similar to what Brian suggested.

thanks,
