https://devzone.nordicsemi.com/f/nordic-q-a/117740/custom-dual-bank-bootloaderHi everyone, I&#39;m quite new to the Nrf Connect SDK and Zephyr. I&#39;m trying to implement a simple DFU (over UART) bootloader. The idea is that when the microcontroller powers on, the bootloader selects the area to boot from and checks if a DFU is requireden-USTelligent Community 13Thu, 09 Jan 2025 14:44:59 GMThttps://devzone.nordicsemi.com/thread/517744?ContentTypeID=1Thu, 09 Jan 2025 14:44:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:42632371-e604-4dd7-bbda-4f9c6935407eAmanda Hsieh<p>It needs Mcuboot running with the&nbsp;<span>SMP server as the course&nbsp;</span><span>to communicate with&nbsp;</span><code><span>mcumgr.</span></code></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/517568?ContentTypeID=1Wed, 08 Jan 2025 23:55:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:87630454-0a24-4dd4-8d9d-425eb765560eCarlosMagni<p>Hi, thanks for your answer !</p> <p>I&#39;m using the NCS v2.7.0, the thing is I don&#39;t want to use mcuboot because the only way to perform a DFU is through another microcontroller (via UART communication) and I wont be able to have mcumgr in CLI as shown in the course</p> <p></p> <p>Regards,</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/517035?ContentTypeID=1Mon, 06 Jan 2025 14:42:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4a8506a9-aaaa-4b3c-895a-abcd9d116741Amanda Hsieh<p>Hi,&nbsp;</p> <p>Which NCS version are you using?</p> <p><span>By default, MCUboot splits the non-volatile memory into two slots. You can look at <a href="https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-8-bootloaders-and-dfu-fota/topic/exercise-1-dfu-over-uart/">this course</a>&nbsp;which demonstrates NCS v2.5.2 - v2.6.2.</span></p> <p><span>Regards,<br />Amanda H.</span></p><div style="clear:both;"></div>
