[Ltib] yaffs image creation seems to have some problem

[Gernot Hillier]

Hi!

I'm having a hard time using a yaffs flash image created by LTIB on an 
ARMv5TE based board (home-brewn LTIB platform).

Therefore I just wanted to ask if someone of you recently used the YAFFS 
image creation functionality in LTIB and can verify that it works 
correctly in the current 10.1.1 release?

I re-used the linux-fsl-2.6.23-yaffs.patch for my kernel and it is 
perfectly able to mount a pre-existing YAFFS partition on flash.

However, when I try to flash the rootfs.yaffs image created by LTIB and 
mount it, the mount seems to be ok, but the image always looks empty (I 
can only see "lost+found").

I tried to verify things as much as I could (same issue occurs when 
mounting rootfs.yaffs from real flash as well as via nandsim.ko, 
rootfs.tmp looks ok as well as the mkfs.yaffs2 commandline).

Unfortunately, there doesn't seem to be a known-to-work, documented 
upstream version of mkfs.yaffs which I could easily try to see if the 
LTIB's version has an issue.

So I wonder if the mkfs.yaffs2 from LTIB was tested recently and is 
known to work or if this whole yaffs stuff is a bit outdated...
