Implement MCUBoot to custom board with dongle&#39;s bootloaderhttps://devzone.nordicsemi.com/f/nordic-q-a/95790/implement-mcuboot-to-custom-board-with-dongle-s-bootloaderI have a custom board with the same hardware configuration than dongle pca10059. This board has the same bootloader than the dongle but I need to upgrade the firmware in a buttonless way. I found this guide: https://developer.nordicsemi.com/nRF_Connect_SDKen-USTelligent Community 13Wed, 18 Jan 2023 11:40:49 GMTRE: Implement MCUBoot to custom board with dongle's bootloaderhttps://devzone.nordicsemi.com/thread/405452?ContentTypeID=1Wed, 18 Jan 2023 11:40:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:12173dc0-24b8-411d-988c-16b85784d853Simonr<p>Hi</p> <p>The buttonless version of DFU in the nRF Connect SDK would be the SMP (Simple management protocol) server, which is a basic transfer encoding for use with the MCUmgr manager protocol. More info on that can be found in <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/services/device_mgmt/index.html#device-mgmt">Device Management</a>. We have an <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/samples/subsys/mgmt/mcumgr/scmp_svr/README.html">SMP Server sample </a>available here to flash a sample image onto a board.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
