Please refer to the chapter-10 of ADSP-21065L User Manual. The minimum size supported for SDRAM is 16 MBytes. If you use any size less than 16 MBytes (as you seem to be currently asking), you will not be able to use some of the address ranges of SDRAM - because these address ranges will be aliased to some other address ranges. For example with 8MByte SDRAM (as you are asking), (1) remaining ...
