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,

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

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

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

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

What is the application you used? Is it your application or example application?

The application is the example "ble_app_buttonless_dfu".

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, 

Please execute the 251064.bat in the 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.
