The settings page cannot be included in a DFU image.&nbsp;</p> [quote user=""]Do you need to pass all the same options again as when using settings generate[/quote] <p>The options are similar, but not identical. You should also make sure to bump the version number as the bootloader will reject downgrades by default.&nbsp;</p> <p><a title="Generating DFU packages" href="https://infocenter.nordicsemi.com/topic/ug_nrfutil/UG/nrfutil/nrfutil_pkg.html?cp=6_5_3">Generating DFU packages</a></p> <p><a title="Generating and displaying bootloader settings" href="https://infocenter.nordicsemi.com/topic/ug_nrfutil/UG/nrfutil/nrfutil_settings_generate_display.html?cp=6_5_6">Generating and displaying bootloader settings</a></p><div style="clear:both;"></div>
