I don't know of people specifically using YAFFS with Nucleus, but YAFFS has
been used successfully with various RTOSs. The YAFFS Direct stuff was written
specifically for this purpose.
Note that to use YAFFS in this way will likely require a licensing deal
(unless you're doing a GPL project). See

YAFFS direct is pretty well tested since this is the primary method using to
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
provide a locking semaphore etc in direct/yaffscfg.c and of course providing
some NAND access functions.
