Please try building and running the pca10100 project instead. You should not see this issue there.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/285008?ContentTypeID=1Tue, 15 Dec 2020 10:44:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:388c15ae-51bb-447d-bf8e-a9c1e7dca16aawneil<p>First thing is to find where the Hard Fault is actually happening.</p> <p>Do you get any debug logs - over RTT or UART ?</p><div style="clear:both;"></div>
