AW: Could not create MTD Partitions

Well, actually I'm not sure. But I found some details
In the manual:

32x Bus DDR
SDRAM w/ ECC

32 MByte=20
128 Mbit (8M x 16 bit) devices
2 Micron MT46V8M16TG-6T
4 MBytes x 4 banks x 2 devices =3D 32 MBytes total
2 bit bank address at 4[BA0,BA1]
12 bit row address at 4K [A0:A11]
9 bit column address at 512[A0:A8]

64 MByte=20
256 Mbit (16M x 16 bit) devices
2 Micron MT46V16M16TG-6T
8 MBytes x 4 banks x 2 devices =3D 64 MBytes total
2 bit bank address at 4[BA0,BA1]
13 bit row address at 8K [A0:A12]
9 bit column address at 512[A0:A8]

128 MByte=20
512 Mbit (32M x 16 bit) devices
2 Micron MT46V32M16TG-6T
16 MBytes x 4 banks x 2 devices =3D 128 MBytes total
2 bit bank address at 4[BA0,BA1]
13 bit row address at 8K [A0:A12]
10 bit column address at 1K[A0:A9]


Are the details for the 64MByte corresponding to that post
from Gerhard?

@Gerhard
Here are some parts of my configuration regarding the MTD settings.
Could you tell which I have to modify to get running the MTD partitions?

Hi all,



I got a problem during creating the MTD partitions. I'm using the

ELDK 4.1 with 2.6.19.2 Kernel and the MPC8343 board with 128MB RAM

and 64MB flash memory.

Are you sure its a single flash chip that is 64M or multiple flash =20
chips?
