Problem with crystal and custom board

Question

Hi, i build my own custom board with a NRF52832, i'm having problem with the softdevice (i think so)... my code is base on BLE s132 central and peripheral... 
 I developed the code and test on a NRF52 DK and it worked all right, everything was ok.. 
 I test a simple code (toggle Leds) in my custom board and it worked ok (No softdevice) 
 I load the softdevice s130 and the code (central device) and my custom board get reset and start again.. I can see when the scanning led turn on and inmediatily restart and start again.. 
 I'm going to paste my init code. Hope you can help me.
