Are there any other options to load a code on top of using the debugger? The main issue here is how we should load the deviceen-USTelligent Community 13Fri, 30 Oct 2015 15:53:08 GMThttps://devzone.nordicsemi.com/thread/37036?ContentTypeID=1Fri, 30 Oct 2015 15:53:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ed8f7f05-75ae-4330-8ac7-7fdc6ae208afStefan Birnir Sverrisson<p>Hi</p> <p>Thank you for your question</p> <p>I can add a littlebit to syntroniks comment</p> <p>Some suggestions on the programming method are e.g. on <a href="https://devzone.nordicsemi.com/question/22056/combining-sd-dfu-and-application-hex-and-programming/?answer=22246#post-id-22246">this thread</a>, update from 28.10.2015. It should identical identical nrfjprog commands for the nRF52 except: use &quot;--program&quot; when programming softdevice instead of &quot;--programs&quot;. Make sure you have updated toolset for nRF52, as described in the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52.v1.0.0/migration/software.html?cp=1_3_2">migration document</a>, section about &quot;toolchain upgrades&quot;.</p> <p>Connections needed in order to program nRF51 are described on <a href="https://devzone.nordicsemi.com/question/3863/pinout-of-p3-swd-on-pca10004-and-pca10005/">this thread</a>.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/37035?ContentTypeID=1Thu, 29 Oct 2015 18:46:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7ef949e9-7d7a-4b84-bb30-b894305e18b4syntroniks<p>I don&#39;t have any production devices yet, but I&#39;m programming my development board with nRFGo Studio &amp; Keil 5. You could probably use nrfjprog or a generic program in production, it is just a cortex M4F anyway.</p><div style="clear:both;"></div>
