https://devzone.nordicsemi.com/f/nordic-q-a/24770/rtt-message-logging-with-power-cyclesGreetings, I&#39;ve got an embedded project where a NRF52 is a &quot;co-processor&quot;. The NRF52 used to output UART debug messages but I&#39;ve since changed this to use RTT. During operation, the main microcontroller frequently performs a power cycle on the NRF52en-USTelligent Community 13Fri, 08 Sep 2017 15:35:36 GMThttps://devzone.nordicsemi.com/thread/97544?ContentTypeID=1Fri, 08 Sep 2017 15:35:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ccd0d14c-aa77-4d07-931b-3f84b01d0997Turbo J<p>How is the debugger&#39;s V_target connection wired up?</p> <p>If it does not see the power drop of the NRF52, there is nothing the debugger can do - it will simply loose the debugging connection as the debug interface inside the NRF will be reset, too.</p> <p>If it could see the power drop it may be possible to restart the debugging interface - but you will probably be much better of using a &quot;high speed&quot; UART(-2USB) connection.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/97543?ContentTypeID=1Fri, 08 Sep 2017 15:14:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:41c31e9b-eab0-436f-be7c-6ff29935d816bjorn-spockeli<p>Several other of my colleauges and I have also seen this issue, but we have not been able to find a solution either.</p> <p>My suggestion would be to contact Segger regarding this issue.</p><div style="clear:both;"></div>
