I have a question about how to enable a 32 MHz crystal oscillator on a custom board? I have 32 kHz and 32 MHz quartz crystals on the board. I found the following config lines to enable 32 kHz: CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=y CONFIG_CLOCK_CONTROL_NRF_K32SRC_50PPM</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Thu, 09 Jan 2025 13:51:52 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/117741/question-about-clock-speed" /><item><title>RE: Question about clock speed</title><link>https://devzone.nordicsemi.com/thread/517726?ContentTypeID=1</link><pubDate>Thu, 09 Jan 2025 13:51:52 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:4b3de60e-ff18-4a3c-987b-edb82ebf7774</guid><dc:creator>Illia Alexandrov</dc:creator><description>&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1736430707368v1.png" alt=" " /&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Question about clock speed</title><link>https://devzone.nordicsemi.com/thread/517600?ContentTypeID=1</link><pubDate>Thu, 09 Jan 2025 07:49:17 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:79d6d625-499a-4073-a61d-c3e6444d63e5</guid><dc:creator>Priyanka</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;In case you get any errors, could you attach a screenshot of what errors that you get after assigning&amp;nbsp;&lt;span&gt;CONFIG_CLOCK_CONTROL_NRF_HFXO=y in your prj.conf&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Question about clock speed</title><link>https://devzone.nordicsemi.com/thread/516920?ContentTypeID=1</link><pubDate>Mon, 06 Jan 2025 08:51:28 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:9493f13b-6c1f-4b65-a4cf-cf3c11b442f2</guid><dc:creator>Illia Alexandrov</dc:creator><description>&lt;p&gt;I get&amp;nbsp;attempt to assign the value &amp;#39;y&amp;#39; to the undefined symbol CLOCK_CONTROL_NRF_HFXO&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Question about clock speed</title><link>https://devzone.nordicsemi.com/thread/516896?ContentTypeID=1</link><pubDate>Mon, 06 Jan 2025 06:40:21 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:7efa82d1-f5cd-4e57-9aa4-1d088dd29d2e</guid><dc:creator>Priyanka</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;The 32MHz should be automatically enabled by default whenever there is a requirement of high-accuracy timing, say, for the radio, peripherals or the CPU.&lt;/p&gt;
&lt;p&gt;Is this not the case?&lt;/p&gt;
&lt;p&gt;If so, please try enabling&amp;nbsp;CONFIG_CLOCK_CONTROL_NRF_HFXO=y in your prj.conf&lt;/p&gt;
&lt;p&gt;Regards,&lt;/p&gt;
