nRF52832 - SDK 15.3 - RTC example: Dummy_Handler loop

Question

Hi all, 
 I am using the nRF52832 and Segger Studio for developing a project. 
 My code is based on saadc, spi and rtc examples from 15.3 SDK. The saadc and spi work fine but when I use the code of the rtc example, especifically when I execute " nrf_drv_clock_lfclk_request(NULL) " function, after the subfunction " nrfx_clock_lfclk_start(); " the program stops at this point and never exits from here: 
 .thumb_func .weak Dummy_Handler Dummy_Handler: b . 
 I am using the same code of rtc example, and I have configured my sdk_config.h according to saadc, spi and rtc clocks, even though I use more peripherals. I have tried to use XTAL and RC for LF clock (changing NRFX_CLOCK_CONFIG_LF_SRC macro at sdk_config.h). RC is used by default for HF clock. I have both externals HF and LF clocks, but I have removed them also. 
 I have compared the codes, sdk_config.h, etc. and I don't know whats is the reason why my code doesn't work and it is blocked at " Dummy_Handler". 
 Please, can anybody help me with this? What is exactly the problem? 
 Finally I would like to share my functions, config file and CPU registers in order to give to the community more info. 
 Thanks. 
 Joaquim.
