Hi,

The first step is to start debugging the issue. How did it "crash"? What state is the device in at that point? What happened just before the crash (logging, error codes, stack trace etc. might give tell you something about what happened.

Build target 'nrf51422_xxac_s110'
linking...
Program Size: Code=41980 RO-data=9804 RW-data=496 ZI-data=4336
FromELF: creating hex file...
"..\..\..\hex\app.axf" - 0 Error(s), 0 Warning(s).

What do you mean by it crashing? Non responsive? Reset? Can you debug to see if any errors are caught? You have to do that via a debug probe. Please see An introduction to error handling in nRF5 projects.
