Hi Terry,

Please execute the 251064.bat in the devzone.nordicsemi.com/.../251064.zip. Please let me know this can run the ble_app_buttonless_dfu on your nRF52832DK or not. If so, you can take a look at the program flow in the 251064.bat.

Hi Amanda,

Maybe my poor presentation.

What I want to say is I have followed your instructions

nrfutil settings generate --family NRF52 --application ble_app_buttonless_dfu_pca10040_s132.hex --application-version 1 --bootloader-version 1 --bl-settings-version 1 bootloaderSettings.hex

mergehex -m ble_app_buttonless_dfu_pca10040_s132.hex bootloaderSettings.hex -o merged.hex

nrfjprog --program merged.hex --sectorerase

nrfjprog -r

However, the ev board cannot run. Seems it hangs

Hi Terry,

If you want to program the ble_app_buttonless_dfu with nrfjprog, you should use the image which merges bootloaderSettings and ble_app_buttonless_dfu instead as I mentioned in the previous reply instead of FW.

Hi Amanda,

I did exactly what you mentioned above.

I could update the application FW through mobile APP and the FW could run on the ev board.

However, the FW could not run on the ev board while I programmed apllication FW using 'nfrjprog'.

That is very frustrating!!!

Hi Terry,

[quote user="terrychan"]Thus, I can program the application image through mobile APP.[/quote]

If you upload the application, you should prepare the package as:

nrfutil pkg generate --application ble_app_buttonless_dfu_pca10040_s132.hex --application-version 1 --application-version-string "1.0.0" --hw-version 52 --sd-req 0xB7 --key-file private.pem FW.zip

If you program the ble_app_buttonless_dfu with nrfjprog (with the programed bootloader + SD), you should prepare the application as:

nrfutil settings generate --family NRF52 --application ble_app_buttonless_dfu_pca10040_s132.hex --application-version 1 --bootloader-version 1 --bl-settings-version 1 bootloaderSettings.hex

mergehex -m ble_app_buttonless_dfu_pca10040_s132.hex bootloaderSettings.hex -o merged.hex

nrfjprog --program merged.hex --sectorerase

nrfjprog -r

Or you can merge your mergedBootloadersettingsApplication.hex and mergedBootloaderSoftdevice.hex to one hex (bootloader+softdevice+setting+app) to program and reset.

Yes, I can see that. Thus, I can program the application image through mobile APP.

The application is the example "ble_app_buttonless_dfu".

What is the application you used? Is it your application or example application? If you use hrs_application_s132 + bootloader setting, you should see the device advertises with the name as "Nordic_HRM" after programing and reset. If you can work with the example application, you could see the step-5--debugging-application-fw-with-bootloader-in-place.

Hi Amanda,

The version of nrfutil is 3.3.2

I am developing on Ubuntu 16.04.

The command I used is as below

nrfutil settings generate --family NRF52 --application application.hex --application-version 1 --bootloader-version 1 --bl-settings-version 1 bootloaderSettings.hex

If I set the '--bl-settings-version' to '2', I got the below error,

Hi Amanda,

I used another PC in which I install the nrfutil version 6.1.0.

I used the below command to generate the bootloader setting

nrfutil settings generate --family NRF52 --application application.hex --application-version 1 --bootloader-version 1 --bl-settings-version 2 bootloaderSettings.hex

And then, I used the below command to program the application + bootloader setting

echo Merging: application.hex and bootloaderSettings.hex
mergehex -m ./application.hex ./bootloaderSettings.hex -o mergedBootloadersettingsApplication.hex

echo Flashing: mergedBootloadersettingsApplication.hex
nrfjprog -f nrf52 --program mergedBootloadersettingsApplication.hex --sectorerase

sleep 2

nrfjprog -f nrf52 --reset

rm -fv bootloaderSettings.hex
rm -fv mergedBootloadersettingsApplication.hex

However, the EV board could not be booted up

Please note that I programmed the bootloader + SD with the below command

echo Merging: bootloader.hex and s132_nrf52_6.1.1_softdevice.hex
mergehex -m ./bootloader.hex ./s132_nrf52_6.1.1_softdevice.hex -o mergedBootloaderSoftdevice.hex

echo Flashing: mergedBootloaderSoftdevice.hex
nrfjprog -f nrf52 --program mergedBootloaderSoftdevice.hex --chiperase

sleep 2

nrfjprog -f nrf52 --reset

rm -fv mergedBootloaderSoftdevice.hex

Hi Terry,

[quote user="terrychan"]I also found that according to this. The '--bl-settings-version' for SDK 15.3.0 was required to be set to '2'. However, I only could set it to be '1' otherwise, I got error.[/quote]

Please provide the complete command you used and the error message.

What is the nrfutil version?

Is it ok for me to set the '--bl-settings-version' to '1'?

Terry — Fri, 12 Jun 2020 07:33:32 GMT

Hi Amanda,

Thank you for your information. They are very helpful.

Now, I can flash the application image to the DK using mobile APP.

However, I still have a problem on flashing the application image using SES. I followed the tutorial to setup the SES.

After I ran the application image, I got the below error.

<error> app: No bootloader was found
<error> app: ERROR 4 [NRF_ERROR_NO_MEM] at /home/15v3_0/sdk/examples/ble_peripheral/ble_app_buttonless_dfu_evboard/main.c:854
PC at: 0x0002FAD1
<error> app: End of error report

But I INSTALLED the bootloader image and the SoftDevice image before.

Hi Terry,

[quote user="terrychan"]I tried just building the examples of 'sdk/examples/dfu/secure_bootloader' and 'sdk/examples/ble_peripheral/ble_app_buttonless_dfu'.[/quote]

Did you mean testing with the unmodified secure_bootloader and ble_app_buttonless_dfu examples here?

To perform the Buttonless DFU Template Application, you have to prepare the image which combines sd + bootloader + buttonless + setting page

In the BLE Secure DFU Bootloader/Testing, it indicates how to get the bootloader HEX file with the bootloader settings. I would also suggest you take a look at the getting started with nordics secure dfu bootloader to know how to prepare the uploaded image.

Would you get still the error after you flash the application with the bootloader and the bootloader setting image?

If you generate the bootloader setting page, could you post the script?

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?

RE: Implementing buttonless_dfu to hrs_freertos

Amanda Hsieh — Thu, 11 Jun 2020 08:54:32 GMT

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 am using PCA10040.

RE: Implementing buttonless_dfu to hrs_freertos

Amanda Hsieh — Thu, 11 Jun 2020 06:40:53 GMT

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,

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: End of error report

Is it related to the project configuration file .emProject?

RE: Implementing buttonless_dfu to hrs_freertos

Terry — Thu, 11 Jun 2020 02:13:57 GMT

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 Terry,

Try to add "DEBUG" to your preprocessor definitions, and see what the log says then.

1. Let me know if you are not sure how to define DEBUG in your preprocessor definitions. If you use the segger, you can compile with Debug mode.

2. The log will probably point to somewhere in your code where it says APP_ERROR_CHECK(err_code); What function call returned that err_code?

3. Your next mission is to find out why it returned that err_code.
