In fact, I remember seeing a link to it on the Nordic website just days ago. However, the links are all broken now, and it&#39;s not listed in Nordic&#39;sen-USTelligent Community 13Mon, 06 Jul 2015 14:34:36 GMThttps://devzone.nordicsemi.com/thread/19923?ContentTypeID=1Mon, 06 Jul 2015 14:34:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fa986f1e-26b0-4fa8-a0d8-76568c52fccdStian R&#248;ed Hafskjold<p>A new tutorial is posted here: <a href="https://devzone.nordicsemi.com/tutorials/7/development-with-gcc-and-eclipse/">devzone.nordicsemi.com/.../</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/19922?ContentTypeID=1Mon, 23 Feb 2015 10:36:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:19e0c5a6-5441-4e86-9689-8bac328d4773Stian R&#248;ed Hafskjold<p>This app note was outdated and did not work on the newer versions of eclipse.
