Warning: set_interface_assignment: Interface "hps_io" does not exist

I'm trying to create an interface to my DDR3 memory connected to the HPS on a Cyclone V. In platform designer I get the warning "Warning: set_interface_assignment: Interface "hps_io" does not exist...

What are the specs for the DDR3 memory that you are using? And what particular FPGA board that you are working on?

I'm using a Micron DDR3L SDRAM MT41K64M16 . Since this is not available in the HPS component, I have selected MT41J64M16 and modified the voltage to 1.35V.

I have updated the input clock to 50MHz, (Clock 2 is not used, but I found no way to disable it, so it is also set to 50 MHz).

Apart from this I believe that it is default settings.

The board is my own design using Cyclone V 5CSEMA5F31C6.
