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

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.

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

What is the nrfutil version? 

C:\WINDOWS\system32>nrfutil version
nrfutil version 5.2.0

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

I think this version is too old to support SDK 15.3 later.

After you program the bootloader + SD, you should see the device advertises with the name as "DfuTarg".

 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.

As replied before, I have continued my testing on another PC and the version of the tool is 6.1.0.

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

Amanda Hsieh said:

The application is the example "ble_app_buttonless_dfu".

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.
