This board turns on when the button is pressed through the power button circuit. And I created the reset function using NVIC_SystemReset(). However, this will turn the board off and not turn on again.en-USTelligent Community 13Wed, 11 Nov 2020 22:42:48 GMThttps://devzone.nordicsemi.com/thread/279597?ContentTypeID=1Wed, 11 Nov 2020 22:42:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c8b9480a-08ad-4009-97d4-9f9c9b689788awneil[quote userid="92575" url="~/f/nordic-q-a/68260/on-a-board-with-a-power-button-circuit-does-the-board-just-turn-off-when-the-system-is-reset"]the custom board[/quote] <p>If it&#39;s a <em>custom</em> board, then nobody knows any details of the hardware design - besides you &amp; your team!</p> [quote userid="92575" url="~/f/nordic-q-a/68260/on-a-board-with-a-power-button-circuit-does-the-board-just-turn-off-when-the-system-is-reset"]<p><span>Does the power circuit prevent the board from turning on when resetting?</span></p> <p></p>[/quote] <p>How can we possibly tell?
