I had assumed that since it was in the git tree, it was being maintained and ready for use. Especially since they keep a close tie with the kernel.org tree. Once I wiped it out and patched it with the latest yaffs code from CVS the fs/yaffs2 compiled. The problem most likely comes from the fact that yaffs2 is maintained outside the kernel and requires the patch-ker.sh. -- Jeff Angielski The PTR Group www.theptrgroup.com
