What do you mean by crash? Will not compile (FPGA)? Crashes as soon as you set one of those inputs to False? Crashes when ran (Scan mode)?

I don't have a cRIO it test this, but my first thought is that the FPGA can't handle the unknown size of data when End is set to False.

To troubleshoot: Try Scan Mode if you're using FPGA mode. Try running on on the development computer rather than the target (to see if it's your code). Also try using Peak Detector PtByPt.vi.
