Hi All,
        I been working on a 2.4.19 kernel with a 2002 mtd snapshot(yes
old but only one working with 2.4.19 for right now :( ) .I have a
samsung k9F1208U0M nand chip on a custom pxa hardware.
dmesg shows me that a mtd partition has been detected
0x00000000-0x00040000 : "Bootloader"
0x00040000-0x00140000 : "Kernel"
0x00140000-0x02000000 : "Filesystem"
NAND device: Manufacture ID: 0xec, Chip ID: 0x76 (Samsung K9D1208V0M)
Creating 1 MTD partitions on "Samsung K9D1208V0M":
0x00000000-0x02000000 : "Filesystem on nand"

[root@manav /root]#cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00040000 00040000 "Bootloader"
mtd1: 00100000 00040000 "Kernel"
mtd2: 01ec0000 00040000 "Filesystem"
mtd3: 02000000 00004000 "Filesystem on nand"

but when i do a
[root@manav /root]#cat /proc/yaffs
YAFFS built:Oct 28 2004 11:35:04

$Id: yaffs_guts.c,v 1.37 2004/10/20 20:12:43 charles Exp $

and thats it . 
mkyaffs /dev/mtd3 does try to format the device but ends up getting a 

nand_read_oob: from = 0x00444000, len = 16
nand_read_oob 1: col = 0, page=2220
Erasing block at 0x08444000

nand_read_oob: from = 0x00448000, len = 16
nand_read_oob 1: col = 0, page=2240
Block at 0x08448000 is damaged and is not being formatted

and mkyaffs -e /dev/mtd3 sample.yaffs gives 
[root@manav /root]#./mkyaffs -e /dev/mtd3 root-balloon-base.yaffs
Image not a multiple of 528 bytes

Shouldnt my /proc/yaffs be showing some entries ?Any clues what is
happening in here ?

regards,
band
