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)

eth1: emac1, MAC 00:50:c2:1e:af:fd

===> 0x003c0000-0x00400000 : "u-boot"
...
Can you see these messages on your system? Is the flash name really
"0"? Are the partitions correct?
