zedboard, fmcomms3, iiostream example

Hi,

I am getting a segfault trying to run the iiostream example program on a zedboard with fmcomms3.  Debug code shows that rx0_i is null (the other channel ptrs probably are too).  I built everything from the following sources:

• hdl: 2014.r2 branch
• kernel: xcomm_zynq branch
• libiio: master branch 

I'm guessing it's important to match up the above branches.  Which should I use?
