 macOS 10.14.6 Segger Embedded Studio 4.20a nRF Connect SDK 1.0 
 Trying with nRF52-DK / nRF52840-DK. 
 When Hex (elf) is downloaded / verified with Segger Embedded Studio, it works normally. It seems that it does not boot when the DK power is turned</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Thu, 10 Oct 2019 13:32:06 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/53044/why-does-nrf-connect-sdk-not-boot-unless-i-press-the-reset-button" /><item><title>RE: Why does nRF Connect SDK not boot unless I press the reset button?</title><link>https://devzone.nordicsemi.com/thread/214396?ContentTypeID=1</link><pubDate>Thu, 10 Oct 2019 13:32:06 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:293f70bf-c15b-4f2a-85ac-8920da9b5687</guid><dc:creator>Kenta</dc:creator><description>&lt;p&gt;Hi Simon.&lt;/p&gt;
&lt;p&gt;The cause was that the sensor was initialized before starting ZephyrOS.&lt;/p&gt;
&lt;p&gt;If the sensor was initialized in the main thread, it worked without problems.&lt;/p&gt;
&lt;p&gt;thanks for the support.&lt;/p&gt;
&lt;p&gt;It was very helpful.&lt;/p&gt;
&lt;p&gt;&lt;br /&gt;Best regards.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Why does nRF Connect SDK not boot unless I press the reset button?</title><link>https://devzone.nordicsemi.com/thread/214392?ContentTypeID=1</link><pubDate>Thu, 10 Oct 2019 13:27:38 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:f0b5f0fa-319a-41ca-a893-786249d0b916</guid><dc:creator>Simon</dc:creator><description>&lt;p&gt;I&amp;#39;m sorry but&amp;nbsp;&lt;a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.0.0/nrf/index.html"&gt;nRF Connect SDK&lt;/a&gt;&amp;nbsp;does not support nRF52840, only nRF9160. To use Zephyr samples on nRF52 series, please&amp;nbsp;&lt;a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/getting_started/index.html#getting-started-guide"&gt;follow this guide&lt;/a&gt;. More information can be&amp;nbsp;&lt;a href="https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/nrf5x-support-within-the-zephyr-project-rtos"&gt;in this link&lt;/a&gt;, and as stated in the bottom of the page: &amp;quot;Also if you want to get involved with Zephyr, or simply need help as a user, you can join the Zephyr&amp;nbsp;&lt;a href="https://lists.zephyrproject.org/mailman3/lists/"&gt;mailing list&lt;/a&gt;&amp;nbsp;or join the #zephyrproject IRC channel.&amp;quot;&lt;/p&gt;
&lt;p&gt;Nordic Semiconductor is part of the&amp;nbsp;&lt;a href="https://www.zephyrproject.org/what-is-zephyr/"&gt;Zephyr Project&lt;/a&gt;&amp;nbsp;and contributes with misc. components/software, but we do not give support for Zephyr running on nRF52840.&amp;nbsp;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;I should have told you this earlier, I am sorry for this.&lt;/p&gt;
&lt;p&gt;Thanks for your understanding.&amp;nbsp;&lt;/p&gt;
