fstorage with nrf51 and sdk12.2

[ANKITTY]

i want to store and retrieve data in flash. i followed steps as in the sdk infocenter but i am not getting the interrupt after fs_store(). Actually return value of fs_store() i am getting success but interrupt is not executed. i changed only the start address of write as in the program // p_config_i->p_start_addr = p_current_end - (p_config_i->num_pages * FS_PAGE_SIZE_WORDS);

to p_config_i->p_start_addr = p_current_end - 50 * FS_PAGE_SIZE_WORDS;

because i think if write in the beginning addresses it may corrupt the board.i AM using a soft device also.is the start address assignment got any problem. so my registered interrupt is not serviced, how to sort out this problem

if any good example program pls share

Could you try this..it would much easy to store data.

		    NRF_LOG_RAW_INFO("store_flag: %d  \r\n", store_flag);
	 }else if( (evt->id == FS_EVT_ERASE) && (result == FS_SUCCESS) ){
		    erase_flag = 0;

Hey, i hope it´s ok if i pick up this question again. I am trying to use the flash storage for some data aswell, but i can´t get the event handler to work, the software seems to stuck after 2 loops after fs_erase FS_SUCCESS.

 while(erase_flag == 1) { power_manage();SEGGER_RTT_printf(0,"loop\r\n"); } 

The event handler doesn´t fire at all. Any ideas?

Best regards

Can you try uncomenting the call to fs_sys_event_handler() on main.c:sys_evt_dispatch()?

That works for me...
