Hi,

I'm trying to shift from Jffs2 to Yaffs, but I have some problems...

Well, I work on a Coldfire platform, with uClinux and a 2.4.22 kernel.

I successfully compiled Yaffs on this distrib, but I've a problem when I 
want to mount a Nand partition with Yaffs.
Actually, it's a Jffs2 partition (empty), so I unmount it, I use 
'mkyaffs /dev/mtd1' to format it, and I use 'mount -t yaffs /dev/mtd1 
/var/parameters' to mount it, but I have this message :

mtdblock_open
ok
yaffs: dev is 7937 name is "1f:01"
yaffs_read_super: MTD block size 4096
yaffs: Attempting MTD mount on 31.1, "1f:01"

I tried to trace it a bit, and it seems there is a problem with 
list_entry stuff...

I must say that this not the last MTD (this is the original MTD from 
uClinux-dist-200412xx distrib) : indeed, I tested newests MTD, but then, 
Jffs2 didn't work and I had some kernel bug panic stuff..!

So, if you have some ideas and/or some advices, I would appreciate it.

Thanks.
Ludovic.
