[U-Boot] Fw:How can I use yaffs2 in uboot

Thank you for your help

NOW with absolute path can write and read (small files)

but When I write large files,such as 50M (Nand flash size is 256M)

Display

yaffs: Could not allocate Tnodes yaffs: Could not allocate Tnodes yaffs: Could not allocate Tnodes ... (Many)

and then restart

my2440 # yls /fash

yaffs: Mounting /flash

yaffs: Could not allocate Tnodes

Error mounting /flash, return value: -12

opendir failed
