 As part of my internship, I am trying to modify an application and send the output of the application via CoAP. My goal is to modify the CoAP Client sample that comes together with nrf-sdk (v.1.4.2). I am using Ubuntu 20.04 and build/program from</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Fri, 05 Feb 2021 13:10:46 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/71353/changing-zephyr-base" /><item><title>RE: Changing Zephyr Base</title><link>https://devzone.nordicsemi.com/thread/293092?ContentTypeID=1</link><pubDate>Fri, 05 Feb 2021 13:10:46 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:65eeea7d-f4d4-4e6f-b0b6-eafbb46360a2</guid><dc:creator>H&amp;#229;kon Alseth</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
[quote user=""]And finally my question: What might be the reason that is causing different behaviors for the two versions of Zephyr bases? And most importantly, is there any way to run the nrf-sdk CoAP Client sample by setting the Zephyr base to ~/zephyrproject/zephyr?[/quote][quote user=""]Let me emphasize that I don&amp;#39;t get this error when I set the Zephyr base to&amp;nbsp;(~/source_code_directory/ncs/zephyr) and the CoAP Sample works.[/quote]
&lt;p&gt;You cannot source the upstream zephyr repo and build a sample with ncs deps, as there&amp;#39;s then no link back to the &amp;quot;nrf&amp;quot; repos. We do follow upstream zephyr as close as we can, but we&amp;nbsp;have smaller changes, like a link in our external repositories, like &lt;a href="https://github.com/nrfconnect/sdk-nrf"&gt;sdk-nrf&lt;/a&gt;, directly in the&amp;nbsp;&lt;a href="https://github.com/nrfconnect/sdk-zephyr"&gt;sdk-zephyr&lt;/a&gt;&amp;nbsp;tree.&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Kind regards,&lt;/p&gt;
&lt;p&gt;Håkon&lt;/p&gt;
