&lt;p&gt;&lt;strong&gt;nrfx_reset_reason_get&lt;/strong&gt;() should&amp;nbsp;work for getting the reset reason. Alternatively the Zephyr hwinfo API should also be usable:&amp;nbsp;&lt;a href="https://nrfconnectdocs.nordicsemi.com/ncs/3.1.1/zephyr/doxygen/html/group__hwinfo__interface.html"&gt;https://nrfconnectdocs.nordicsemi.com/ncs/3.1.1/zephyr/doxygen/html/group__hwinfo__interface.html&lt;/a&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
&lt;p&gt;Simon&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
