FW works on nRF51 DK but when I flash in my target board it doesn't.

I developed an application based on ble_app_uart and it is working on my nRF51 DK. I can see the ports driven by my application responding and Bluetooth communication is working perfectly.

I generated the HEX file as "Additional output format" in the Linker option and flashed it on my target board using JLink.

Well, the controller of my target board just doesn't start!

Does the HEX file contain the Soft Device? What am I doing wrong?

Have you tried debugging the application, to see if any code is executed, and if any errors are reported?
