Are you able to run BLE applications? If you can do BLE you can be sure that you have handled the LF clock is working correctly. It shouldn't be necessary to change anything other than the setting is the wizard.

Here is my code for nrf5 sdk 12

                             bsp_event_handler);
 APP_ERROR_CHECK(err_code);
 err_code = bsp_btn_ble_init(NULL, &startup_event);
 APP_ERROR_CHECK(err_code);
 *p_erase_bonds = (startup_event == BSP_EVENT_CLEAR_BONDING_DATA);

@ Martin

Yes, except i have to change the pin definition correspondingly
Yes.
This is due to the hardware limitation.

Just a thought...is it possible due to the absent of 32768 crystal and somehow i do not configure to use internal RC properly? I have set the CLOCK_CONFIG_LF_SRC to RC in Configuration Wizard. Do i need to change any code in the project files??

Thanks

So the exact same code works on the nRF51, but not your custom board?
I assume you have double checked that you use the correct pins?
Is there a reason why you configure Button 1 without pullup resistor, and button 2 with pullup?

Thanks Amigo, tried to add this but it makes no difference (also the original code works in NFF51 DK board do not need it)

Below are the code i initialize the buttons...

static void buttons_leds_init(bool * p_erase_bonds)
{    
	uint32_t err_code;
	static app_button_cfg_t p_button[] = {{BUTTON_1, APP_BUTTON_ACTIVE_HIGH, NRF_GPIO_PIN_NOPULL, button_handler},		
											  {BUTTON_2, APP_BUTTON_ACTIVE_LOW, NRF_GPIO_PIN_PULLUP, button_handler}};	
				
	APP_GPIOTE_INIT(APP_GPIOTE_MAX_USERS);																					
	// Initializing the buttons.
	err_code = app_button_init(p_button, sizeof(p_button) / sizeof(p_button[0]), BUTTON_DEBOUNCE_DELAY);
	
	APP_ERROR_CHECK(err_code);																					
	err_code = app_button_enable();	
	APP_ERROR_CHECK(err_code); 
}

NVIC_EnableIRQ(GPIOTE_Irqn) ?
