Hi all,

Please help me if you have able to access HPS DDR3 memory for your processing.

My problem is:

I have used malloc for reserve memory in DS-5 code.so I got one start address.now I pass the same to my DMA write start address .so DMA in qsys will start write data from that location.

Now I want to read that location form DS-5 code.

so I need to translate that address to read data from HPS DDR3 memory? if yes ,How?

Thanks in advance.
