You won't be able to use any file system with NAND unless you can write the
OOB.
All file systems I am aware of at the very least use OOB for storing ECC etc.
Have a look at the code for mkyaffs. This should give you a good kick-off
point for programming YAFFS. I am aware of at least one smartphone
manufacturer pre-programming NAND chips directly with YAFFS.
