https://devzone.nordicsemi.com/f/nordic-q-a/11865/bricked-dead-running-cannot-connect-to-any-nrf-deviceSo, I have made 3 custom boards (all boards have the same layout, with a nrf51822AC) and I&#39;ve been able to develop code. I&#39;ve been using the swd lines from the nrfdk (pca10028) to flash code onto my custom boards.

I suspect that your RSSI levels might be due to imperfect matching. Alternately you can post them here, and we will do our best to assist you.</p> <p>From my understanding the error is only present in one of the boards, were all the boards functional originally and is it possible that something got fried the first time you programmed it?</p> <p>Best regards,</p> <p>Øyvind</p><div style="clear:both;"></div>
