KC705 and AD9567-FMC-250-EBZ - Issue with capturing a large number of samples

I am trying to run an experiment where I need to capture around 1 second of data from the ADC so I can analyse it off line and develop a signal processing algorithm.


Using the reference design on the wiki page for the board I have been able to read out over the UART port a small number of samples (2000) when capturing at 250MHz, please see attached the modified main.c code which allows me to do this.  When I increase the loop count to larger figures such as 300K (ideally 250M to get me 1 second) my system seems to fall over or get stuck.


Can you provide any insight into why this is happening?
