ADPS-21469 accessing full DDR2 memory range

I am currently using ADSP-21469 EZ board with 128 MB DDR2 memory (64M x 16).

The memory map defines a range starting from 0x0020 0000 to 0x21F FFFF for external DDR2 memory.

This address range represents 32M words (16 bits) so half of the total available space available in the DDR2.

I am wondering if the other 32M part of the memory can be accessed and how?


Best regards,
