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;

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
