Matlab IIO streaming to AD9364

I am using the AD-FMCOMMS4-EBZ board in conjunction with the Xilinx ZED board to test the AD9364 transceiver chip.  Attached is a Matlab program ad9364test.m and associated configuration file ad9364.cfg.  I have defined a subframe to have 10000 samples at a sample rate of 1 MHz.  It appears that 5 subframes must be sent before one receive frame can be captured (N=5).  If I lower N to less than 5, then no RX data is received.  I N is raised higher than 5, then the RX only contains one subframe of data.

 

Questions:

1.  Is there a way to reduce the start-up latency?

2.  How do I capture consecutive subframes?

3.  Is there a maximum sample rate for a given frame size?
