I would recommend having a look at the <a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/releases/release-notes-3.0.0-preview2.html">changelog.</a>&nbsp;</p> <p>undefined reference to `__device_dts_ord_112&#39; typically means that there is something lacking in the dts file. What is new in DTS in NCS 3 is among other things that&nbsp;</p> <ul> <li>Device tree and driver initialization ordering has become stricter.</li> <li>Some device tree nodes or aliases may have changed.</li> <li>Kconfig options or shield/board overlays may need updates.</li> </ul> <p>It is hard immediately to say exactly what is at fault though.</p> <p>Regards,</p> <p>Elfving</p><div style="clear:both;"></div>
