&lt;div&gt;
&lt;pre&gt;&lt;code&gt;nrfjprog.exe --snr &amp;lt;your_jlink_debugger_serial_number&amp;gt; --memwr 0x10001008 --val 0xFFFFFF00
&lt;/code&gt;&lt;/pre&gt;
&lt;/div&gt;
&lt;p&gt;This will make 32MHz crystal to be used by default instead of 16MHz crystal.&lt;code&gt;&lt;/code&gt;&lt;/p&gt;
