pwm can not work with softdevice, when i use s110(v7.1) , sdk 6.1

Hi Nordics,

I copy pwm sample code into my proximity project, to drive a buzzer .

I init pwm before softdevice. but, once "SOFTDEVICE_HANDLER_INIT" is excuted, the buzzer pin no longer toggle.

My question is , softdevice use TIMER0, my pwm use TIMER2, it seems that they are independent two modules. why pwm not working ?

Many thanks !

I found this example is for NRF51422, so I changed project settings. 1, select device 'nRF51822_xxab' 2, set IROM1: start at '0x18000', size '0x28000' 3, set IRAM1: start at '0x20002000', size '4000'

rebuild, there are 18 errors:
