[USRP-users] 512 DDR3 SDRAM on E310

Howdy,

I'm trying to use the SDRAM attached to the FPGA on the E310.  Has anyone
tried to do this?

I think I narrowed the part number down to Micron MT41K256M16HA-125 IT.  I
tried the Xilinx Memory Interface Generator to make the interface.  I used
the schematic to place the pins.  Upon validation, however, I get the error

ERROR : The port ddr3_addr[0] is allocated in the bank 33 where the input
ports are allocated. Enable the Internal Vref to use the Vref as GPIO.

What do I do here?

Thanks,
Jeremy
