 I have two sets of hardware, one is nrf52840 DK, and the other is my own board. I use the same program, update package and mobile phone. When using nrf52840 DK, the firmware update is normal, and when using my own board, NRF_ Toolbox reports GATT</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Fri, 10 Sep 2021 03:53:51 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/79408/devic-firmware-update-duf-over-ble-by-nrf-toolbox" /><item><title>RE: Devic Firmware Update (DUF) Over Ble by nrf Toolbox</title><link>https://devzone.nordicsemi.com/thread/328906?ContentTypeID=1</link><pubDate>Fri, 10 Sep 2021 03:53:51 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:a7cb77c4-071b-4810-baa5-30e52ff86f4c</guid><dc:creator>xiang san </dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;&amp;nbsp; &amp;nbsp; I have solved the question ,It&amp;#39;s the clock crystal oscillator.&lt;/p&gt;
&lt;p&gt;Thank&amp;nbsp; you very much!&lt;/p&gt;

Do you have the spec or part number for the 32 MHz crystal?

&lt;p&gt;OK,this is my schematic:&lt;/p&gt;
&lt;p&gt;&lt;a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/feeder_5F00_52840_5F00_v1.1.4.pdf"&gt;/cfs-file/__key/communityserver-discussions-components-files/4/feeder_5F00_52840_5F00_v1.1.4.pdf&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;can you find something wrong?&lt;/p&gt;
&lt;p&gt;According to my debugging, I found that using the &amp;quot;nrf_connect&amp;quot; app , the DK board can enter dfutarg, but my own board cannot display the Bluetooth name&amp;nbsp;of dfutarg. that&amp;#39;s why?&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;I have found the queston and sloved it.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Thank you very much!&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Devic Firmware Update (DUF) Over Ble by nrf Toolbox</title><link>https://devzone.nordicsemi.com/thread/328618?ContentTypeID=1</link><pubDate>Wed, 08 Sep 2021 13:06:40 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:bebbab8a-6f82-4a07-a6d0-7d720eba9101</guid><dc:creator>ketiljo</dc:creator><description>&lt;p&gt;What&amp;#39;s the difference between your custom HW and the DK?
