Vladimir,

I've checked the FM, and it made me go through the datasheet of MT48LC4M16
again. I've found that the page size of that SDRAM is 256 B and the BF531
supports page size 512 B or more, so that might be one of those problems I
have (anyway, I got some data from that working). So now I'll wait for the
final word from Analog and see if they got any recommendations.

Then you are out of luck.

Well, not realy, I just need to replace it with a different one. I've took
a look and the MT48LC16M16 (32 MB) is pin compatible with my MT48LC4M16 (8
MB), it has just one more address pin connected (will connect that missing
pin with wire), so it will be no bit deal :)

We use the MT48LC4M16A2P-7E IT:G with a BF532. I would lay iy out for the
larger part. This gives you a universal footprint.

Al, do you got it working all ok? Because I have the feeling from the
manuals that there might be some issues with it.

My SDRAM setup looks like this:
*pEBIU_SDRRC = 0x00000816;
*pEBIU_SDBCTL = 0x00000001;
*pEBIU_SDGCTL = 0x00911149;
