What is XIP XIP, short for eXecute In Place, translates to “Execute In Place” or “Execute On Chip”. It is a design feature of computer systems that … Read more
We were working on a smart streetlight control system, deploying over 100,000 terminals nationwide, with the core being the STM32F429. The system periodically receives OTA firmware updates via a 4G network, automatically rebooting after the upgrade, completely unnoticed by the users. The initial OTA tests went smoothly, and everyone gradually got used to the automatic … Read more
When it comes to bootloaders, many newcomers to embedded systems might find it a bit unfamiliar. What exactly is it? Simply put, it is the first program that runs when a device is powered on, acting as the “guide” for device startup. Whether it’s the smartphones and computers we use daily or the microcontrollers and … Read more

For ARM-Linux program development, it is mainly divided into three categories: application development, driver development, and system kernel development. Each type of software development has its own characteristics.Today, we will look at the differences between ARM-Linux development and MCU development, as well as the basic development environment for ARM-Linux.1. Differences Between ARM-Linux Application Development and … Read more
The RZ/G2L microprocessor is equipped with a Cortex®-A55 (1.2 GHz) CPU, a 16-bit DDR3L/DDR4 interface, a 3D graphics acceleration engine with Arm Mali-G31, and a video codec (H.264). Additionally, this microprocessor features a variety of interfaces such as camera input, display output, USB 2.0, and Gigabit Ethernet, making it particularly suitable for entry-level industrial human-machine … Read more
From routers to smart speakers and industrial controllers, the flexibility of Linux and the prevalence of low-cost processors have made it a paradise for developers. Even more astonishing is that in China, you can currently buy a development board capable of running Linux for less than 100 yuan, which is practically a steal. The goal … Read more
First Encounter with bareboxHey, I’ve been experimenting with embedded booting recently, and I was captivated by a project called barebox. It is not just a simple follower of U-Boot; it inherits the spirit of U-Boot while also drawing on the design philosophy of the Linux kernel. Written in C and managed with kbuild/Kconfig for configuration, … Read more
1. Overview of MCUboot MCUboot is an open-source, secure bootloader designed specifically for microcontrollers (MCUs). It was originally part of the Mynewt project and has since become the standard bootloader for RTOS such as Apache NuttX and Zephyr. MCUboot provides a secure firmware update mechanism and supports multiple boot modes, ensuring that the system can … Read more
