Are you sure that your flash device name in Linux is just "0" ? Which
board is this?

The kernel boot messages  contain  a  section  about  MTD  partitions
found, something like this:


	...
	io scheduler noop registered
	io scheduler anticipatory registered
	io scheduler deadline registered
	io scheduler cfq registered
	RAMDISK driver initialized: 4 RAM disks of 4096K size 1024 blocksize
	loop: loaded (max 8 devices)
	PPC 4xx OCP EMAC driver, version 3.53
	mal0: initialized, 4 TX channels, 2 RX channels
	eth0: emac0, MAC 00:50:c2:1e:af:fe
	eth0: found Generic MII PHY (0x00)
	eth1: emac1, MAC 00:50:c2:1e:af:fd
	eth1: found Generic MII PHY (0x01)
	PPChameleon: Found 1 x16 devices at 0x0 in 16-bit bank
	 Amd/Fujitsu Extended Query Table at 0x0040
	PPChameleon: Swapping erase regions for broken CFI table.
	number of CFI chips: 1
	cfi_cmdset_0002: Disabling erase-suspend-program due to code brokenness.
===>	Creating 3 MTD partitions on "PPChameleon":
===>	0x00000000-0x00180000 : "linux"
===>	0x00180000-0x003c0000 : "user"
===>	0x003c0000-0x00400000 : "u-boot"
	...

Can you see these messages on your system? Is the flash  name  really
"0"? Are the partitions correct?

Best regards,
