MCUboot can be configured to be the first code that the CPU executes upon power-on. As such, it is laid out at the start of flash at location 0x0. MCUBoot then boots other applications that are stored in flash. MCUBoot is also responsible for updating the application via a Device Firmware Update (DFU).


- After rebooting, MCUBoot starts the Minimal DFU Firmware, which will accept MCUBoot-based firmware for flashing - The MCUBoot-based firmware replaces the Minimal DFU Firmware Switching modes with Companion App - The PineTime Companion App (e.g. Gadgetbridge) will switch modes automatically depending on the firmware to be flashed.

The nRF Connect SDK includes a fork of the MCUboot project. This fork is kept as close to the original repository as possible, but it might contain some additions that are specific to Nordic Semiconductor devices and applications. Creating a MCUBoot-compatible application. We will be doing a multi-image build which means that the application will be compiled along with MCUBoot. There is no need to compile MCUBoot separately in NCS. In the NCS nomenclature, the application is known as the parent image and MCUBoot is the child image.

This is mcuboot version 1.8.0-dev. MCUboot is a secure bootloader for 32-bit MCUs. The goal of MCUboot is to define a common infrastructure for the bootloader, system flash layout on microcontroller systems, and to provide a secure bootloader that enables simple software upgrades.


All code examples included in the SDK are tailored to compile for and run on Nordic Semiconductor's nRF5 Development Kits. For documentation, release notes, and licenses, see the nRF5 SDK documentation overview. Installation. The SDK is delivered in the following formats: SDK zip installer.

• You can tick the Enable MCUboot field to program the Nordic Thingy:91™modem through USB. • In the Device Memory Layout, you can read the name, address range, and size of a memory section by hovering the mouse cursor over one of the memory sections. This option is possible only after loading a memory layout. 1159720_170 v1.3.07

Keep in mind that resetting the device using the RESET button will always enter Nordic nRF5 bootloader’s DFU mode. Finally, perform a firmware update using mcumgr as follows: Nordic Q&A MCUboot ECIES encryption.

I have one nrf52840_pca10056 chip integrated on my custom board, which has mcuboot as a bootloader. I don't have any direct pin access to the nrf chip.

Implementations using MCUboot have even been incorporated in semiconductor provided SDKs such as Nordic’s nRF Connect SDK 1 for the NRF91 & NRF53 MCUs. If you are working on a new project, MCUboot is worth a look! Nordic Q&A v1.5.0 MCUboot build fail.

I used the MCUboot update method and everything worked as expected. I updated the modem firmware and then was able to reprogram the application. I followed the steps in the link above. I tried to use the MCUboot update method but kept getting the following error: "MCUboot DFU failed. Please make sure that the device is in MCUboot mode and try

The mcumgr CLI app already has a flag to choose the image pair where to upload, image upload -n , which can be used to choose between S/NS, but this currently uploads in a fixed slot.I don't remember if the mcumgr library supports this, but MCUboot surely does. With the XIP support it will probably also get an extra flag for 2020-01-09 2020-09-22 Project Slinky using the Nordic nRF52 Board¶.
