 due to unknown reasons, my nrf52840-DK (1.0.0) didn&amp;#39;t come back up after flashing software to it. Means the LED that usually turns on when you power it up remains off.

&lt;p&gt;Have you tried turning off the dev kit &amp;amp; holding in the Reset button on the DK while powering it back on. You should then see the device appear as a Bootloader drive. You should then be able to drag &amp;amp; drop &lt;a href="https://www.nordicsemi.com/Software-and-Tools/Development-Kits/nRF52-DK/Download#infotabs"&gt;this file&lt;/a&gt;&amp;nbsp;(i.e. interface MCU FW)&amp;nbsp;to the DK. Afterwards, power cycle the DK &amp;amp; you should see the DK work as a JLINK device again.&lt;/p&gt;
&lt;p&gt;Regards,&lt;/p&gt;
&lt;p&gt;Bjørn&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
