How can I use yaffs2 in uboot
I add CONFIG_YAFFS2 in /include/configs/smdk2410.h
my2440 # nand write 0x30008000 80000 40000
NAND write: device 0 offset 0x80000, size 0x40000
262144 bytes written: OK
my2440 #
my2440 # ymount /flash
yaffs: Mounting /flash
my2440 # ywrm a 0x30008000 40000
Error opening file: -1

Maybe you try a "yls" first to check which files are present in your file system. Then test if read accesses are working. I'm not sure if write mode has been tested (or even implemented).
Also, it might make sense to enable YAFFS2_DEBUG while testing.

You have to use absolute path with all commands. eg "yls /flash/" This path must match your mount points as configured in fs/yaffs/yaffscfg.c

Write mode is in use and working.
