Hi.

You need change in Pin Planner:

DRAM_LDQM to DRAM_DQM[0]

DRAM_UDQM to DRAM_DQM[1]

and

DRAM_BA_0 to DRAM_BA[0]

DRAM_BA_1 to DRAM_BA[1]

And then, you can assign these pins to your Nios II as buses.

DRAM_DQM[1..0]

DRAM_BA[1..0]

You must do this because Nios II in SOPC Builder 9.1 SP2 has buses for these connections to the SDRAM

I hope to be clear enough :)
