Reset pin(P0.18) of NRF5280 is measured lowhttps://devzone.nordicsemi.com/f/nordic-q-a/59662/reset-pin-p0-18-of-nrf5280-is-measured-lowhi I`m debugging the nrf52840 on the pcb I made and have some problem I know Reset pin is P0.18 of nrf52840 but 3.3V was not measured. So the reset pin does not work. I think the reason why the reset pin does not work is related to 3.3V.

Note that the <a href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/power.html#unique_1418146595">PINRESET needs to be enabled by writing UICR registers</a>. The default (reset) value is 0xFFFFFFFF, which means that the RESET pin is disconnected. You&nbsp;can enable pin reset with the <a href="https://infocenter.nordicsemi.com/topic/ug_nrf5x_cltools/UG/cltools/nrf5x_nrfjprogexe_reference.html">nrfjprog command</a> &#39;nrfjprog --pinresetenable&#39;.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
