I am currently trying to receive 16-bits of data from the EMIF from
one of the connectors on the DSK. What I want to do is look at this
data at a memory location and do some decisions based upon the value.
The question I have is, how do I get this data from the location the
EMIF uses to store it? I believe the data is stored in CE1, so do I
point to the starting address of 0x9000000? Any help would be greatly
appreciated!
Thanks,
David

David,
Try 0xA0000000 [CE2] or 0xB0000000 [CE3].

Will reading in data from an external daughtercard and storing it in
CE2 or CE3 via EMIF cause bus contention with the other devices on
the board? If so, how can I not cause the contention.

David,
The only "contention" will be for the time that it takes to do a memory
read or write.
Just to clarify - when you read/write from/to add 0xA0000000 the CE2 signal
will be sent out to enable the daughtercard hardware. A memory read or
write cycle will take place.
