https://devzone.nordicsemi.com/f/nordic-q-a/67399/nrf52811-reset-pinHi, I have a problem with the reset pin not working on the nrf52811. The firmware was developed on the nrf52840dk board and now that we are migrating to the real nrf52811 chip the reset won&#39;t trigger. Here is the Makefile for the project where we removeden-USTelligent Community 13Tue, 20 Oct 2020 13:57:05 GMThttps://devzone.nordicsemi.com/thread/275963?ContentTypeID=1Tue, 20 Oct 2020 13:57:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:344a0d3a-207f-43f9-bffc-4b3a98a5837cVojislav<p>The problem was with UICR registers, that&nbsp;had rest pin value, when I did --eraseall as you suggested, everything was ok.<br /><br /></p> <p>Thanks a lot!<br /><br />Best regards,<br />Vojislav</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/275927?ContentTypeID=1Tue, 20 Oct 2020 12:48:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:079f398c-e8cb-4897-80ed-1d4235d74e64Kenneth<p>Hi,</p> <p>First check that the CONFIG_GPIO_AS_PINRESET works as intended in system_nrf52811.c; In other words that the correct pin 21 is written to UICR (it will only check that a value is written, not that it is pin 21 when using nRF52811, so you may need to execute an &#39;nrfjprog --eraseall&#39; first to erase UICR).&nbsp;</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
