This looks like what happened to me when trying to upgrade to the latest
version of yaffs.

We were using the yaffs kernel config option:

YAFFS_DISABLE_TAGS_ECC set to "y"

When upgrading to the latest version of yaffs, this option is still
available in Kconfig, but the code to support it is gone, it is now only
available as a mount option.

Since this config option was missing when the new version of yaffs
mounted my filesystem, yaffs interpreted all my blocks as bad, and
erased everything, leaving only a lost+found folder. This happened even
if the filesystem was mounted read-only.

Perhaps this is what's happening to you as well? If yaffs expects a
different ECC layout/config than it gets, then this matches the
behaviour I've seen.
