https://devzone.nordicsemi.com/f/nordic-q-a/54547/issues-with-mergehex-nrf52811Having a bizarre issue with mergehex and DFU. I hadn&#39;t had a problem with this previously with this code base. When I try and merge the App, Bootloader, Bootloader Settings and SD I get the following when I program the chip: ERROR: The file specifieden-USTelligent Community 13Tue, 19 Nov 2019 15:02:25 GMThttps://devzone.nordicsemi.com/thread/220910?ContentTypeID=1Tue, 19 Nov 2019 15:02:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:62e4dcbd-857b-4775-b581-9bd09926d12cbjorn-spockeli<p>HI Dave,&nbsp;</p> <p>if the merged hex is intended for the nRF52811, then you need to use the --family NRF52810 option when generating the settings page for the bootloader. Otherwise, the settings page will be placed at 0x7F000, which is way out side the 192kB( 0x30000) of the nRF52811.&nbsp;</p> <p>Best regards</p> <p>Bjørn</p><div style="clear:both;"></div>
