[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

Good.

I cannot recall having seen that error, but I don't think I have ever tried
with files larger than 20MB. Besides our out of tree port have started to slightly move away from upstream U-boot.
I suggest you try to debug your problem. "yaffs_traceMask" in fs/yaffs/yaffscfg.c is probably your friend.

Sounds like a pretty clear error message - doesn't it?
Increase CONFIG_SYS_MALLOC_LEN in your bard config file.
[It might make sense to improve the error message in fs/yaffs2/yaffs_guts.c to include information how many bytes were to be allocated, so you get an idea on how uch to increase the malloc arena size.]
