Dear sir,

I have created the Custom component of CDMA_ENCODING and CDMA_DECODING as per Mr.Kevin Jennings suggestions.

NIOS-->(S)CDMA_ENCODING(M)-->(S)CDMA_DECODING-->slave

Now , while building my own system in SOPC builder.

i added components in this order.

NIOS

ONCHIP MEMORY

CDMA_ENCODING

CDMA_DECODING

SLAVE(SD RAM).

I am getting these errors:

cpu_0:nois ii instruction master cannot address memories over 2^32.

cpu_0:nois ii data master cannot address memories over 2^32.

memory map cannot fit within the addressable memory space of the nios ii data master which is restricted to 31 adress bits..

my both address and data masters are 32-bit only.

what is the cause of this error, and suggest me the possible solution .

thank you.
