https://devzone.nordicsemi.com/f/nordic-q-a/106905/reset-after-flashI have a custom board that is based on the nRF9160 DK. I&#39;ve copied the board definition files and made some minor alterations for pinouts, but that&#39;s about it.

Sorry for the inconvenience.&nbsp;</span></p> <hr /> <p>The nRF52 on the nRF9160DK <a href="https://infocenter.nordicsemi.com/topic/ug_nrf91_dk/UG/nrf91_DK/board_controller.html">works as the board controller and&nbsp;controls analog switches</a>&nbsp;on the&nbsp;<span>nRF9160 DK</span>, enabling routing of some of the nRF9160&nbsp;GPIO&nbsp;pins to onboard functionality, for example LEDs, or the regular GPIO interfaces.

If you wish to mimic this process, find or create a mechanism replicating this action in your settings.</p> <p>A good start would be inserting JTAG into a DK bootloader or flipping the constant &#39;1&#39; GPIO of 3rd party on an interrupt from the bootloader.&nbsp;</p><div style="clear:both;"></div>
