Can you verify that you are able to perform an application DFU with the pre-made test images by following the BLE Secure DFU Bootloader Testing guide?

If you are able to successfully perform DFU with the test image, then please answer the following questions:

Does the DFU process finish without any errors? If so does the device advertise as DfuTarget after the update or does it not advertise at all?
If you debug the bootloader, do you reach the nrf_bootloader_app_start(MAIN_APPLICATION_START_ADDR); call in nrf_dfu_init() in nrf_dfu.c?
How did you generate the Application DFU image with nrfutil? Please post the commands as well as the nrfutil version.

Hi Suzhou,

could you please explain in detail what that is not working.

Does the DFU process finish without any errors? If so does the device advertise as DfuTarget after the update or does it not advertise at all?
If you debug the bootloader, do you reach the nrf_bootloader_app_start(MAIN_APPLICATION_START_ADDR); call in nrf_dfu_init() in nrf_dfu.c?
How did you generate the Application DFU image with nrfutil? Please post the commands as well as the nrfutil version.

Best regards
