How can I use `nrfutil` to make `dfu` packages that don&#39;t use a SoftDevice?https://devzone.nordicsemi.com/f/nordic-q-a/41886/how-can-i-use-nrfutil-to-make-dfu-packages-that-don-t-use-a-softdeviceAs per description, I don&#39;t understand how to make a dfu package that writes the whole MBR+Application range and doesn&#39;t use a SoftDevice, for example out of a hex file such as \examples\zigbee\light_control\light_bulb\hex\nrf52840_xxaa.hex .

If you want to update just the application (no softdevice) you can just use --sd-reg 0x00 and don&#39;t provide softdevice hex.&nbsp;</p> <p>The MBR can&#39;t be updated with DFU. MBR need to be flashed by a programmer.&nbsp;</p><div style="clear:both;"></div>
