Hangs at iio_device_create_buffer

I have a dev system based on FMC carrier board and FMCOMMS4-EBZ. With it I can run the IIOstream example and copt RF input to RF output. Great.

However,when using my own carrier board with the AD9364 device and the same PicoZed from my dev system the iiostream example hangs here:-

        rxbuf = iio_device_create_buffer(rx, BUFFERSIZE , false);// Enabled Cyclic Receive

Obviously some signal  is missing compared to the FMC carrier and FMCOMMS system but i can not see what signal would cause the code to hang here. Can anyone help me?

I can see the carrier frequency output of the AD9364 on a spectrum analyser and change it in /sys/bus/iio/devices~etc . I have all the devices shown in /dev/iio~
