Updating firmware with dfu bootloader

Geoffroy

Hi,

i would like to program my module nRF52840 via uart.

I generated private then public key using nrfutil.exe tool

i could programm softdevice and bootloader and flash them on my nRF52840.

I use : https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v11.0.0%2Fbledfu_example_serial.html

now i want to update firmware, first i'm testing an existing package : softdevice_s140.zip (nRF5_SDK_15.0.0_a53641a\examples\dfu\secure_dfu_test_images\uart\nrf52840)

so i try to execute this cmd : 

D:\Work\nRF5_SDK_15.0.0 ble_telechargement_uart\examples\dfu\secure_dfu_test_images>nrfutil.exe dfu serial --package softdevice_s140.zip --port 4 -fc 1 : here is the result : 

D:\Work\nRF5_SDK_15.0.0 ble_telechargement_uart\examples\dfu\secure_dfu_test_images>nrfutil.exe dfu serial --package softdevice_s140.zip --port 4 -fc 1
