FDS after Init show ok,but always waitting for ready

[Panda]

Hi,

I  want to add FDS basedon  dimming_serve example ,However,after fds_init(); it  not jump to fds_evt_handler but stop wait .

The below is my code:

static void initialize(void)
{
    __LOG_INIT(LOG_SRC_APP | LOG_SRC_ACCESS | LOG_SRC_BEARER, LOG_LEVEL_INFO, LOG_CALLBACK_DEFAULT);
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "----- BLE Mesh Dimming Server Demo -----\n");

    ERROR_CHECK(app_timer_init());
    hal_leds_init();

    ble_stack_init();

#if MESH_FEATURE_GATT_ENABLED
    gap_params_init();
    conn_params_init();
#endif

    //mesh_init();

    uint32_t status = app_pwm_init(&PWM0, &m_pwm0_config, NULL);
    APP_ERROR_CHECK(status);
    m_pwm0_max = app_pwm_cycle_ticks_get(&PWM0);
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "PWM max ticks: %d\n", m_pwm0_max);

    #if 1
    //FDS
    /* Register first to receive an event when initialization is complete. */
    status=fds_register(fds_evt_handler);//(void) fds_register(fds_evt_handler);
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Status fds register is : %d\n",status);

    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Initializing fds...\n");

    status=fds_init();
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Status fds init is : %d\n",status);
    APP_ERROR_CHECK(status);

    /* Wait for fds to initialize. */
    wait_for_fds_ready();
    #if 0
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Available commands:\n");
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "- print all\t\tprint records\n");
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "- print config\tprint configuration\n");
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "- update\t\tupdate configuration\n");
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "- stat\t\tshow statistics\n");
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "- write\t\twrite a new record\n");
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "- delete\t\tdelete a record\n");
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "- delete_all\tdelete all records\n");
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "- gc\t\trun garbage collection\n");
    #endif

    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Reading flash usage statistics...\n");

    fds_stat_t stat = {0};

    status = fds_stat(&stat);
    APP_ERROR_CHECK(status);

    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Found %d valid records.\n", stat.valid_records);
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Found %d dirty records (ready to be garbage collected).\n", stat.dirty_records);

    fds_record_desc_t desc = {0};
    fds_find_token_t  tok  = {0};

    status = fds_record_find(CONFIG_FILE, CONFIG_REC_KEY, &desc, &tok);

    if (status == FDS_SUCCESS)
    {
        /* A config file is in flash. Let's update it. */
        fds_flash_record_t config = {0};

        /* Open the record and read its contents. */
        status = fds_record_open(&desc, &config);
        APP_ERROR_CHECK(status);

        /* Copy the configuration from flash into m_dummy_cfg. */
        memcpy(&m_dummy_cfg, config.p_data, sizeof(configuration_t));

        __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Config file found, updating boot count to %d\n", m_dummy_cfg.boot_count);

        /* Update boot count. */
        m_dummy_cfg.boot_count++;

        /* Close the record when done reading. */
        status = fds_record_close(&desc);
        APP_ERROR_CHECK(status);

        /* Write the updated record to flash. */
        status = fds_record_update(&desc, &m_dummy_record);
        APP_ERROR_CHECK(status);
    }
    else
    {
        /* System config not found; write a new one. */
        __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Writing config file...\n");

        status = fds_record_write(&desc, &m_dummy_record);
        APP_ERROR_CHECK(status);
    }

   #endif
}

And The Bellow is Log:

<t: 0>, main.c, 558, ----- BLE Mesh Dimming Server Demo -----
<t: 17925>, ble_softdevice_support.c, 124, RAM Start is 0x20002DA0
<t: 17945>, main.c, 575, PWM max ticks: 1600
<t: 17948>, main.c, 581, Status fds register is : 0
<t: 17950>, main.c, 583, Initializing fds...

How To solve this ? TKS in anvance.

Hi, 

When adding fds (and fstorage) care should be taken to avoid overlapping the flash area occupied by the mesh flash manager module. We have a guide here about integrating Mesh into nRF5 SDK and vice versa. 

How do you configure the fds module ? and fstorage module ? 

Do you need to use fds or it's possible to use flash manager from mesh instead ?

Hi Hung,

   I have read the guide and The bellow is what i did:

      1)set the Heap Size to 8192 bytes in project option

      2)in nrf_mesh_config_app.h file add include and define

      3)for the "optional changes"and "Flash palcement project files"part ,the code has alreadly been existed.

  I have enable FDS_ENABLED 1 in file sdk_config.h

  My purpose is to storage data  which  power on again after user's setting.

 The new Log:

I have pressed  RESET Button four times. The process stopped after 'fds_record_write' this time.

Could you give me some advices.Thanks.

Best Regars,

Hi Panda, 

Could you provide the full project so I can test here ? I assume you are testing using SDK v3.2 ? 

Which value you used for FDS_PHY_PAGES ? 

Please make sure you erase full flash before testing. 

Which backend for fstorage you used ? NRF_FSTORAGE_SD or NRF_FSTORAGE_NVMC ?

[Panda]

Hi Hung,

   I send you main codedimming_server_DFU.rar   ,Just extract it and place path ：...\nrf5_SDK_for_Mesh_v3.2.0_src\examples\experimental_dimming .

   nRF SDK:     nRF5_SDK_15.3.0_59ac345

   mseh SDK:  nrf5_SDK_for_Mesh_v3.2.0_src 

   I used NRF_FSTORAGE_SD  fstorage (example default) .FDS_PHY_PAGES=3*1024/1024=3 （fds_internal_defs.h and sdk_config.h)

  If anything else is needed,Please tell me .Thank you for you help.

Best Regards,

Hi Panda, 

I think we found what's wrong with the code.  You forgot to include INITIALIZE_USER_SECTIONS in the preprocessor definition. 

Without that the section variable will not be initialized with the value defined in the section register.
