AD9361 No Os driver

Hi,

I am able to run no os driver on Altera SOC platform.

In 1Tx1Rx mode i am getting harmonics in spectrum analyzer.

After initialization as given in example design what output should come in TX port?

What data can i route to AD9361 via DAC and How?

because when i call dac_init(phy,DATA_SEL_DMA);

                                     dac_datasel(1,DATA_SEL_DMA);

whatever spurious was coming that has gone.  Please help us in how can i feed data to DAC -->AD9361?

Regards
