Implementing buttonless_dfu to hrs_freertos

[Terry]

Hi,

I am developing the 'buttonless dfu' to the 'hrs freertos' using the SDK v15.3.0.

However, after I compiled the modified code and loaded to the target broad, I got the below error.

    <info> app: nrf_sdh_ble_enable() err:0 ram_start:0x20002258
    <error> app: Fatal error

Is there any example for this application?

Thanks

Hi Amanda,

Thanks for your help.

Yes. I am using SEGGER Embedded Studio in my development.

After enabled the DEBUG mode, I got more information about this issue as below.

    <info> app: nrf_sdh_ble_enable() err:0 ram_start:0x20002210
    <error> app: ERROR 4 [NRF_ERROR_NO_MEM] at /home/15v3_0/sdk/examples/ble_peripheral/ble_app_hrs_freertos_dfu/main.c:648
PC at: 0x0002DF83
    <error> app: End of error report

And, the error was reported after calling sd_ble_uuid_vs_add().

Hi Amanda,

Finally, I found out the solution by setting NRF_SDH_BLE_VS_UUID_COUNT to 1.

However, after I built and programmed the 'sdk/examples/dfu/secure_bootloader' to the development board, I got the below error returned by fds_init() in the appliction FW.

<info> app: nrf_sdh_ble_enable() err:0 ram_start:0x20002220
<error> peer_manager_pds: Could not initialize flash storage. fds_init() returned 0xB.
<error> peer_manager: pm_init failed because pds_init() returned NRF_ERROR_STORAGE_FULL.
<error> app: ERROR 3 [NRF_ERROR_INTERNAL] at /home/15v3_0/sdk/examples/ble_peripheral/ble_app_hrs_freertos_dfu/main.c:940

<error> app: End of error report

Is it related to the project configuration file .emProject?

Hi Terry, 

fds_init() return 0x0B meaning FDS_ERR_NO_PAGES.

Which board are you using? Are you using pca10040e on nRF52832 DK?

Hi Amanda,

I am using PCA10040.

Hi Terry,

The error message seems that the flash area for flash storage has been erased. Please check the number of FDS_VIRTUAL_PAGES (in your application) reserved for the FDS storage match with NRF_DFU_APP_DATA_AREA_SIZE inside the bootloader. By default, they are 3 pages. (12kB).

Hi Amanda,

I checked that FDS_VIRTUAL_PAGES is 3 while NRF_DFU_APP_DATA_AREA_SIZE is 12288.

I tried just building the examples of 'sdk/examples/dfu/secure_bootloader' and 'sdk/examples/ble_peripheral/ble_app_buttonless_dfu'.

After loaded the bootloader image through 'SEGGER Embedded Studio -> Debug', the bootloder could run.

Then, I loader the application image through 'SEGGER Embedded Studio -> Debug', the problem occurred.

That means I got the same problem even, I just built and loaded the example codes.

Do you know what is the problem?
