https://devzone.nordicsemi.com/f/nordic-q-a/111105/52811-nreset-invalid-problemI originally had a case using the 52832 QFN48 package, but then the customer needed to use the 52811 functionality. We found that the PIN definitions of 52811 and 52832 on the QFN48 are the same, so we replaced 52832 with 52811 without any modificationen-USTelligent Community 13Tue, 14 May 2024 07:23:28 GMThttps://devzone.nordicsemi.com/thread/483168?ContentTypeID=1Tue, 14 May 2024 07:23:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:10fc55f8-a738-4ee2-97ee-d4a5d3932585Simonr<p>Hi</p> <p>Do you have any external pull-up of any kind on the nRF52811 reset pin? If it was working as expected on the nRF52832 it should also work as intended for the nRF52811 AFAIK, so please also double and triple check your soldering.&nbsp;</p> <p>If that doesn&#39;t solve anything either, please create a private case where you upload the schematics and PCB layout files for the design so we can review it on our end.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
