https://devzone.nordicsemi.com/f/nordic-q-a/112758/mcu-boot-logs-swap-issueHi, I evaluate MCUBOOT and trying to understand how it works. I am using a nRF52840DK. I have base my demo on this course ( Exercise 1 - DFU over UART - Nordic Developer Academy (nordicsemi.com) ) I would like to do DFU through UART and seeing log,en-USTelligent Community 13Mon, 08 Jul 2024 08:23:25 GMThttps://devzone.nordicsemi.com/thread/492626?ContentTypeID=1Mon, 08 Jul 2024 08:23:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2c963e10-e87b-4157-8b4f-99728de4e20eMenon<p>Hello,</p> <p>I&#39;m glad to hear that your issue has been resolved.</p> <p>Kind regards,</p> <p>Abhijith</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/492479?ContentTypeID=1Fri, 05 Jul 2024 13:51:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0fd4a2bc-e975-4f22-a674-c729610d4545evan_nxlc<p>Hello,</p> <p>Increasing the buffer size to 2048 allows more messages to be displayed.<br />Thanks for your proposition.

This may be due to the log buffe. Can you try increasing the log buffer(<a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/kconfig/index.html#CONFIG_SEGGER_RTT_BUFFER_SIZE_UP">CONFIG_SEGGER_RTT_BUFFER_SIZE_UP</a>)?</p> <p>From the logs, I can see that you are on version 2.7rc2. I recommend updating to the stable version 2.7.0.</p> <p>Kind regards,</p> <p>Abhijith</p><div style="clear:both;"></div>
