Hello everyone,

I just try to connect the MT48LC64M4A2 SDRAM (16 Meg x 4 x 4 banks) to
my 5307.
I want to use 8 Chips (each with 4 bit data bus). How do I have to
connect and initialise it? The coldfire Init-Tool seems to be confused
with this configuration.
It shows the following config:

ColdFire Pin:    A15 A14 A13 A12 A11 A10 A9 A17 A19 A21 A23      A24 A25
A26 A27
SDRAM Pin:       A0  A1  A2  A3  A4  A5  A6 A7  A8  A9  A10(CMD) BA0 BA1
BA2 BA3

But I only have 4 Banks (BA0 and BA1)! I use 11 Bit column adress A0..9
+ A11. Portsize is 32 Bit.
Where is my fault?

Greetings

Frank
