Enable OFDM modulator AD9364 + KC705 : dac_init problem

I have a problem with AD9364 NoOS driver in AD9364 mode.

I have a KC705 board and AD9364 evaluation card. Moreover, I use Vivado2013.4 and a HDL ref design for AD9364 Compatible to this Vivado Version.

When I run the SDK with the given NoOS driver, normally it should work when I keep


0  two_rx_two_tx_mode_enable,

0  frequency_division_duplex_mode_enable,


under the dfault_init_param in main.c script.

But the problem is when I set these value zeros I do not observe anything transmitted or received.

But when I make then '1'. It works.


Why it is so? Did you observe the same problem at your end?

Please note that I am unable to test new release of your driver, when I run it I do not see any output. Should I update my ref HDL design as well?

Because the problem is I can not test new HDL ref because it is for Vivado 2014 but I still have Vivado 2013.4 and for the moment everything works for this ref design. May be later on I will switch to new Vivado.

Please let me know if you need any information regarding this problem.

Best regards,
