Custom board reboot at high cosumption

[navarrocantero]

Hi, I have a problem with my custom PCB.

Im ussing Segger in Mac, the latest sdk (15.02) and the latest softdevice too. 

I have a custom pcb with a buzzer and when i try to turn on, the pcb lost the connection and reboot itself.

But the strange its that, if i have the jlink wire connected the buzzer works like a charm and dosnt reboot.

Can you help me please¿? thanks !
