Hi
I have a set of 8 1GB data flash chips (Samsung) on an MPC8245 Ref. Board.
These are on a 64-bit bus-mode.
---DBUS_SIZ[0-1]:DBUS_SIZ[2] = 110b ---
All 8 chips are selected by a single chip select (RCS1). Trying a 32-bit read
from the Data Address Location after giving the Command
Are you sure you are not using software floating points?

32 bit reads should be easy: reading 32 bits should cause a 64 (full width)
read since you only have one chip select and the processor will ignore the
32 bits it doesn't want. I'm confused when you say you have only one chip
select but then say only 4 chips respond when you do a 32 bit read.

Steve,
I tried to use fp assembly instructions (like lfd). But my assembler has
problems and doesnt let me generate my

I am not very clear as to:
(a) How do we perform writes to send out data out on
all 64-bits of the bus..?
(b) How would we ideally access 64-bit data through 32-bit reads..?
(c) Or must we *have* 64- bit read/write
instructions..?
This has been
