Nordic Semiconductor announces the introduction of the 'Thingy:91' rapid cellular IoT prototyping platform. Read more!

nRF Connect for Desktop is a cross-platform tool that enables testing and development with Nordic’s products for Bluetooth® Low energy and cellular IoT. It allows easy setup of connections with other devices and uses these connections to read and write the external nodes. Separate downloads are provided for Windows, Linux and macOS.

The following configuration can replace this outdated information to enable Nordic QSPI storage of non-primary image data for MCUBOOT, as long as #25292 is also present: For devicetree: diff --git In #22562 (comment) and following comments, we discuss how to make it easier to build zephyr applications to be chain-loaded by MCUboot. In short, we agreed on auto-generating signed binaries, provided sufficient information about how to generate them is available in .config. This PR implements that. If accepted, I will write a follow-up PR that teaches west flash to use the signed binaries by - 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. 2021-01-01 MCUboot was chosen as the bootloader to be used with the Zephyr RTOS 1. Implementations using MCUboot have even been incorporated in semiconductor provided SDKs such as Nordic’s nRF Connect SDK 1 for the NRF91 & NRF53 MCUs.

Open nRF Connect for Desktop and launch nRF Connect Programmer. Connect Nordic Thingy:91 to the PC with a micro-USB cable. • 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 mbolivar-nordic changed the title build: imgtool integration or MCUboot build: imgtool integration for MCUboot Aug 19, 2020 mbolivar-nordic force-pushed the mbolivar-nordic:build-imgtool-integration branch 4 times, most recently from 26f788a to 4fd514e Aug 19, 2020 Multi-sensor cellular IoT prototyping platform The Nordic Thingy:91 is an easy-to-use battery-operated prototyping platform for cellular IoT using LTE-M, NB-IoT and GPS. It is ideal for creating Proof-of-Concept (PoC), demos and initial prototypes in your cIoT development phase.

Select the MCUboot compatible firmware image file (with the extension .hex) from the zip file that you have downloaded from the Nordic Thingy:91 Downloads page, using the file browser that opens up. Note: A normal firmware image HEX file cannot be used when programming applications through USB, since the MCUboot bootloader is used.

RIOT is currently supported as a boot target with a complete port planned. The Nordic Thingy:91 comes complete with a global use SIM card from iBasis that has a free 10 MB data plan to get you up and running immediately. The Thingy:91 and SIM can be provisioned and monitored using nRF Connect for Cloud which is Nordic Semiconductor’s cloud demonstration, evaluation and test platform. Nordic Thingy:91 product brief [PDF] Programming the modem through USB (MCUboot) You can program the modem of Nordic Thingy:91 by putting the device into serial recovery mode. Programming the modem through an external debug probe You can program the modem of Nordic Thingy:91 by using an external debug probe.

Running mynewt apps with MCUboot¶. Due to small differences between Mynewt’s bundled bootloader and MCUboot, when building an app that will be run with MCUboot as the bootloader and which at the same time requires to use newtmgr to manage images, MCUboot must be added as a new dependency for this app.

Project Slinky using the Nordic nRF52 Board¶. This tutorial shows you how to create, build and run the Slinky application and communicate with newtmgr for a Nordic nRF52 board.

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. MCUboot is a secure bootloader for 32-bit MCUs. The nRF Connect SDK includes a fork of the MCUboot project.

Project Slinky using the Nordic nRF52 Board¶. This tutorial shows you how to create, build and run the Slinky application and communicate with newtmgr for a Nordic nRF52 board. Prerequisites ¶. Meet the prerequisites listed in Project Blinky.. Have a nRF52 Development Kit (one of the following) Nordic nRF52-DK Development Kit - PCA 10040.

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
