AD9467+Zedboard Matlab Sampling rate and trigger signal

Hallo,

 

I am using the AD9467-FMC-250EBZ with a Zedboard. The Zedboard run with a Linux OS from the Zynq & Altera SoC Quick Start Guide. I  aquire the data with matlab and used the IIO System Object guide to set it up. It works, but how can i change the Sampling rate in the matlabscript?

 

I want to record the data from a mesure system, who wait for a trigger signal to send a THz pulse and recive the returning signal. The trigger should have a duration of approx 0.2 micro seconds. To send a trigger signal and record data with the AD9467, i think i have to modify the hdl and the driver, to add a Pmod output during data record. My second Question is: how do i modify the hdl and maby the AD9467 driver of the Linux distribution?

 

I saw the ZED HDL Reference Design on AD9467 Native FMC Card / Xilinx Reference Design [Analog Devices Wiki] , but is this the same as in the Linux distribution? And where can i update it?
