I don't know of people specifically using YAFFS with Nucleus, but YAFFS h=

been used successfully with various RTOSs. The YAFFS Direct stuff was wri=

specifically for this purpose.

Note that to use YAFFS in this way will likely require a licensing deal=20
(unless you're doing a GPL project). See=20

YAFFS direct is pretty well tested since this is the primary method using=

test yaffs_guts (ie. the internal file system algorithms).

It should not be **that** difficult.

The actual RTOS porting just involves filling out a few stub functions to=
=20
provide a locking semaphore etc in direct/yaffscfg.c and of course provid=
ing=20
some NAND access functions.
