Hi Chris,
Currently, YAFFS2 has a dependency on the correct release of the MTD
code. This mainly has to do with MTD's AUTOPLACE feature that YAFFS2
knows nothing about.
Your best bet is to go to
http://www.toby-churchill.org/ and download
the linux-2.4.25 kernel that has a working MTD/YAFFS2 combination. See
http://www.aleph1.co.uk/pipermail/yaffs/2005q2/001172.html for more
information.
I don't know about 2K-aware mkyaffsimage or mkyaffs.
