In previous blog we have used sample key available in MCUboot repository for signing the application image. But it is strictly advised to use custom keys for production purposes or else attacker may modify the application image in flash and take control of the device. In this blog we are going to generate the custom…
In the previous blog post, we have build and flashed the sample application for disco_l475_iot1 board using Zephyr RTOS. In this post we are going to build and flash the same sample application with MCUboot (Bootloader). What is a MCUboot? Here, MCU stands for Microcontroller and boot stands for bootloader which provides a secure…
Zephyr, a project of The Linux Foundation backed by major tech companies like Intel, Nordic Semiconductor, NXP, Linaro and much more companies developing and maintaining a small real-time operating system for connected, resource constrained devices supporting multiple architectures and targets. Zephyr is released under Open Source Apache License 2.0 This blog is a short tutorial…
In our previous post, we have explored basic details about Introduction to Provisioning and it’s needs. In this post we will narrow down our use case and experiment how it works. As mentioned in our previous post, we will use Hardware: Phytec Phycore imx6UL/ULL SoM Storage: eMMC We will assume that the hardware…
Development of various Embedded Hardware in market based on various architectures are currently available as various consumer to industrial solutions. Hardware manufacturer also provide Board Supported Package (BSP) to get the hardware up and running with basic system software. Based on various requirements and use cases, these software are engineered in various ways and customized…
