In this mode, the DIF (debugger interface) is detached, and you cannot flash. Try unplugging the USB and reconnecting it, and try to flash your application then. If that does not work, you can use the &quot;recover&quot; option in nRFgo Studio.</p> <p>The new error message you are seeing &quot; &#39;No CPU DLL specified&#39;&quot; indicated that your project setting has been altered. Try with another example, or &quot;restore&quot; the specific project that you have.</p> <p>Best regards Håkon</p><div style="clear:both;"></div>
