 I noticed this in SDK 2.5 
 nRF52840 based device boots and functions as expected but the RTT log is filled with same messages ( timestamps are identical ) - see below 
 Logging is configured as follows 
 
 CONFIG_LOG =y

&lt;p&gt;Still occurs in the latest JLink 7.94e&lt;/p&gt;
&lt;p&gt;I listed my kconfig options above&lt;/p&gt;
&lt;p&gt;I noticed this started to happen when I switched to SDK 2.5&lt;/p&gt;
&lt;p&gt;I&amp;#39;ll try revert back to 2.2 and will let you know if the problem goes away&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: RTT log is filled with same message</title><link>https://devzone.nordicsemi.com/thread/464617?ContentTypeID=1</link><pubDate>Wed, 17 Jan 2024 13:42:52 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:103befce-bc3e-4773-93dd-f79187af3d91</guid><dc:creator>Kenneth</dc:creator><description>&lt;p&gt;Hello,&lt;/p&gt;
[quote user=""]... same messages repeat multiple times. All the while device functions properly so it&amp;#39;s not like it&amp;#39;s rebooting.[/quote]
&lt;p&gt;Not seen reports of something similar before, I can only suggest to try other samples and see if you see the same, and possible try different kconfig options. Also possible try to update nRF Comment line tools (including j-link driver from segger).&lt;/p&gt;
&lt;p&gt;Edit: I can see you have made a case afterwards where it doesn&amp;#39;t seem you experience this anymore, were you able to resolve this?&lt;/p&gt;
