Thank you Al,
I got it working with your help and with the help of ADI e-mail support -
the memory is mapped to 4 regions per 2 MB now:
- 0x000000 - 0x1fffff
- 0x400000 - 0x5fffff
- 0x800000 - 0x9fffff
- 0xC00000 - 0xdfffff
Best regards,
Jookie

Our settings for BF 532 with SCLK = 132MHz
*pEBIU_AMBCTL1 = 0xFFFEFFFE;
*pEBIU_AMBCTL0 = 0xFFFEFFC0;
*pEBIU_AMGCTL = 0x00F3;
*pEBIU_SDGCTL = 0x819199CD;
*pEBIU_SDBCTL = 0x0005; //0x0013 for 256 Mb 0x0005 for 64 Mb
*pEBIU_SDRRC = 0x008C3;

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;

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.

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 :)

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.

Hello Vladimir,
thank you for your answer. I'm still not sure if the SDRAM controler inside
the BF531 can do it, so I've wrote an e-mail do AD technical support - I
will see if I will get an answer and what it will be :)
Best regards,
Jookie
