Unable to initialize the FDS module

[Muhammad Akram Karimi]

Hello,

I wanna use FDS module and started with FDS example given in SDK 11.

I have used the exactly same functions for initialization but it seems like FDS module is not getting initialized.

I have searched the forum and found some people facing the same problem but there fixes did not work for me. That is why I raised this question, may be I am missing something else.

Here is the sequence in which I am initializing my modules.

I am posting this because this post FDS Initialization Failed reports that the wrong initialization sequence may result into FDS initialization error but I have taken this into consideration but to no avail for my case.

// Initialize.
    timers_init();			//It calls APP_TIMER_INIT which should be called once
		buttons_leds_init(&erase_bonds);
		ble_stack_init();
		
   
		//Step2 in DB discovery ::  Initialize the db_discovery module with ble_db_discovery_init() in main().
		db_discovery_init();
		os_c_init();				//Our Service Init STH
		
		gap_params_init();
    conn_params_init();
		services_init();
		advertising_init();
    
		//device_manager_init(erase_bonds);
    peer_manager_init(erase_bonds);
		

		/****************		TEST FDS		*****************/
		
		err_code =fds_test_init();
		APP_ERROR_CHECK(err_code);
		while(fds_init_done==0);												//Waiting for initialization event for FDS
		

Here is the code for the "fds_test_init" which is same as in example.

static ret_code_t fds_test_init (void)
{
	
		ret_code_t ret = fds_register(my_fds_evt_handler);
		if (ret != FDS_SUCCESS)
		{
					return ret;
		}
		ret = fds_init();
		if (ret != FDS_SUCCESS)
		{
				return ret;
		}
		
		return NRF_SUCCESS;
		
}

Can anyone help me identify why my flag "fds_init_done" is never set to 1.

while I am setting it the FDS event handler as follows:

 switch (p_fds_evt->id)
    {
        case FDS_EVT_INIT:
            if (p_fds_evt->result != FDS_SUCCESS)
            {
                // Initialization failed.
            }
						else if (p_fds_evt->result == FDS_SUCCESS)
            {
                // Initialization succeeded
								fds_init_done=1;
            }
            break;

Your help will really be appreciated.

Thanks

Update 1:

I have recently tested the fds_example_master code (without any change) downloaded from github here FDS Example.

I am getting the same error i.e. err_code=0x2 in fds_test_find_and_delete(); function which means that the FDS module is not initialized.

Can anyone test the example code and verify this.

I am using SDK11.

Thanks

Did you remember to add fs_sys_event_handler(..) to sys_evt_dispatch()?

static void sys_evt_dispatch(uint32_t sys_evt)
{
    // Dispatch the system event to the fstorage module, where it will be
    // dispatched to the Flash Data Storage (FDS) module.
    fs_sys_event_handler(sys_evt);

    // Dispatch to the Advertising module last, since it will check if there are any
    // pending flash operations in fstorage. Let fstorage process system events first,
    // so that it can report correctly to the Advertising module.
    ble_advertising_on_sys_evt(sys_evt);
}
 // (SDK 12.3.0)

Dear Kristin,

It's already there in the main file in sys_evt_dispatch().

You can also check in the link I downloaded the source code from. as I mentioned in UPDATE 1 .

Dear Kristin,

I guess, this is not the problem of registering the event handler.

Because I have just checked that my app goes into the my_fds_evt_handler()

BUT p_fds_evt->result != FDS_SUCCESS

Please check the code below

static void my_fds_evt_handler(fds_evt_t const * const p_fds_evt)
{
    switch (p_fds_evt->id)
    {
        case FDS_EVT_INIT:
            if (p_fds_evt->result != FDS_SUCCESS)
            {
                // Initialization failed.
            }
						else if (p_fds_evt->result == FDS_SUCCESS)
            {
                // Initialization succeeded
								fds_init_done=1;
            }
            break;

Could you test this example and check if it works at your side?
