https://devzone.nordicsemi.com/f/nordic-q-a/93924/can-t-do-debug-in-real-boardHi, I am currently having a project which is communicating between nrf52811 and nrf9160. I have an issue in nrf52811 when I try to check or debug in realboard. I already did the flash for the board and all the process is completed.

I actually did not know that not enabling this option could lead to a verification error. I will keep this in mind if I see anyone else report the same.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/396079?ContentTypeID=1Wed, 16 Nov 2022 19:12:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a703cefe-7106-41de-9ec6-230b06c92495azwawe<p>Hi, thanks for your help Vidar. I am using a custom board. But now I manage to debug it. The issue was I didn&#39;t activate the <strong>download to flash</strong> again for debug like the picture below.</p> <p><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1668625955225v1.png" alt=" " /></p> <p>Again, really thanks.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/395946?ContentTypeID=1Wed, 16 Nov 2022 10:44:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e4f820de-697d-4456-a239-5616da5d0711Vidar Berg<p>Hi,</p> <p>The verification error indicates that there may be a HW issue. Is this a custom board you have designed, or is it a board you have bought from a third party?</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
