DAC38J82: FPGA access to EVM using SPI

Part Number: DAC38J82

I am trying to program DAC38J82 EVM via FPGA (Xilinx). 

I see following for SPI access, and JP3 on EVM to be changed to FMC position

sclk : c14 
sdio : c15 
sdo : d14 
sen_dac: d15
sen_lmk: g15

Are there any other signals needed to access. I have not set SDIO and SDO as pullups. Also, due to FPGA bank sharing with other signals, I can only use 1.8V for it. I am still not able to access.

Thanks,
