nrf51822 Not Running

We have 2 identical development boards and have been using only one until now. I was able to download code into the 2nd board successfully but it will not run. It does not run in either standalone or debug mode (PICKit3). What are the likely causes?

"Does not run" means that it will not run code. If I put a simple test to turn on an LED and nothing happens. It will not single step or run to a breakpoint in debug mode. On the second board it runs the code as expected.

My mistake. The programmer/debugger is a Segger. (Working on 2 project simultaneously hence my confusion).
