Issue with NRF_SDH_SOC_OBSERVER

Question

Hi, 
 I use NRF52840 on a custom board. I am utilizing low-level SoftDevice flash API for accessing flash: 
 sd_flash_page_erase() and sd_flash_write(). 
 
 I want to register an event handler so that I can received notification when the flash operation is done and also to receive the status. 
 I did it by calling NRF_SDH_SOC_OBSERVER as follow: 
 NRF_SDH_SOC_OBSERVER(m_soc_evt_observer, 0, FlashEvtHandler, NULL); 
 However, I got this compile error: "the size of an array must be greater than zero" 
 What did I do wrong? 
 Does it refer to m_soc_evt_observer? I couldn't find its declaration in the library nor in the example code. 
 
 Thank you.

Hi. 
 Then you should enable that one as well. That will enable the SoftDevice Handler SoC Module. 
 And sorry, I made an error in my previous reply, what I ment by enabling the SoftDevice handler was to set the following in sdk_config: 
 // <e> NRF_SDH_ENABLED - nrf_sdh - SoftDevice handler
//==========================================================
#ifndef NRF_SDH_ENABLED
#define NRF_SDH_ENABLED 1
#endif 
 Best regards, 
 Andreas
