The Linux kernel has long been a cornerstone of operating systems across diverse environments, from enterprise servers to embedded systems. While its robust design and modularity make it versatile, the standard Linux kernel is not inherently designed for real-time operations. To transform the Linux kernel into a real-time operating system [...]
Today, over 90% of organizations depend on open-source software (OSS) within their applications. OSS powers much of the tech we use daily, from Google and Amazon to our phones, cars, and countless apps. Once a niche concept in the ’90s, OSS has surged in popularity, especially with the demand for [...]

Board support packages (BSPs) are software components that serve as a bridge between an operating system (OS) and the hardware of a particular computer board. They are commonly utilized in embedded systems, which are integrated into various devices or products.A BSP is a software component that enables the operating system [...]
Devtool is undoubtedly one of the best tools in embedded Linux and Yocto. It allows developers to easily change or patch the source code of any recipe easily. Suppose you have a calculator recipe in Yocto and want to change its code or functionality. You can easily do it via [...]
FreeRTOS is an open-source, real time operating system for microcontrollers/Embedded devices which allows devices to execute multiple processes at the same time. Let’s quickly discuss difference between OS (Operating System) and RTOS (Real-time Operating System) before digging deep into the topic for better understanding. Operating System: Operating System is a [...]
Almost every electrical and embedded system engineer has used Arduino once in a lifetime. It is one of the most affordable and easy-to-learn microcontrollers to learn embedded systems. However, there is a little confusion about the programming language to program Arduino boards. Therefore, every engineer asks, “Which Programming Language does [...]
Makefiles are important for every programmer as it makes code compilation easier. In this tutorial, I will tell you the importance of Makefiles. Besides, I will also guide you about compiling your first program with makefiles here. So lets get started! Why Makefiles are Necessary? In C or C++, you [...]
You might have seen many embedded systems nowadays where you can control everything from a display screen like a mini-computer. Most of these systems are based on Embedded Linux systems. Generally, Linux runs on computers like x86. However, Embedded systems have limited memory, speed, and other resources. But you want [...]
Kernel is considered as the most important part of any operating system. Therefore, It is necessary for every engineer and computer enthusiast to understand the role of the kernel in the operating system. Here we will discuss the role of kernel in any operating system in simplest possible manners. After [...]
