SD+BL+APP DFU update failure

Rafalino

Hi everyone ,

I want to perform DFU of SD+Bl+APP via UART.

I use nrfutil version 6.1.3.

The Softdevice is s140_nrf52_7.2.0_softdevice.hex and the application is based on SDK 17.0.2.

I prepared a ZIP file using :

nrfutil pkg generate --hw-version 52 --application-version 3 --application ../images/brg/version_3.0.0/3.0.0.hex --sd-req 0x00,0x0100 --softdevice ../images/brg/version_3.0.0/s140_nrf52_7.2.0_softdevice.hex --sd-id 0x0100 --bootloader ../images/brg/version_3.0.0/brg-secure_bootloader_uart_3.0.0.hex --bootloader-version 3 --key-file ../images/bootloader/private.key ../images/brg/version_3.0.0/3.0.0.zip

The zip contains: 

  • 3.0.0.bin
  • 3.0.0.dat
  • sd_bl.bin
  • sd_bl.dat
  • manifest.json

This is the manifest file : 

{
    "manifest": {
        "application": {
            "bin_file": "3.0.0.bin",
            "dat_file": "3.0.0.dat"
        },
        "softdevice_bootloader": {
            "bin_file": "sd_bl.bin",
            "dat_file": "sd_bl.dat",
            "info_read_only_metadata": {
                "bl_size": 24340,
                "sd_size": 153140
            }
        }
    }
}

When I call nrfutil dfu serial --package 3.0.0.zip -p COM7 -fc 0 -b 115200 -t 10  it starts upgrading the but stops after 53% (probably after upgrading the sd_bl).

version_3.0.0>nrfutil dfu serial --package 3.0.0.zip -p COM7 -fc 0 -b 115200 -t 10

Can anyone suggest what is the problem and how to fix it ?

Thanks in advance ,

Rafalino.
