AD9361 DMA problem

Hi,

I'm currently using FMCOMMS3-EBZ+ML605+NO-OS driver and i can't get an output signal in dma mode (#define DAC_DMA).

While debugging I noticed that program gets stuck at this point

But if variable "length" is manually changed to less then 0xBF program runs to the end, and there is output signal which is very lame (using default lut table there has to be sine wave, but i get dc with rf signal inside).

 

How can I fix this?

 

Thank you very much.
