I am working on Ubuntu, SEGGER Embedded Studio for ARM Release 5.50d, ncs 1.6.99 version. After compile, I tried &quot;Connect J-Link&quot;.

Though you shouldn&#39;t&nbsp;need to worry about that, it should be the right project by default.&nbsp;</p> <p>You&nbsp;also don&#39;t need to actively connect to J-Link using the Target drop-down menu. As long as it is built, simply&nbsp;selecting <em>download zephyr.elf</em> be sufficient.</p> <p>Best regards,</p> <p>Elfving</p><div style="clear:both;"></div>
