Embedded devices—whether automotive ECUs, IoT sensors, or industrial controllers—face increasing cyber threats during both boot and runtime. From firmware tampering to memory exploitation, attackers often target early boot stages and exploit runtime weaknesses to compromise the entire device. If you’re wondering how to secure embedded devices throughout their full lifecycle, [...]
Rust has become one of the most loved programming languages in the last few years due to its drastic features related to memory management and low-level control. Due to its rich features it has become first language after C to be used for Linux kernel development. In this tutorial, we [...]
Do you have any rust application and want to cross-compile it for some other hardware using Yocto? If yes, you are at the right place. In this article, we will tell you how to make a yocto recipe for rust applications easily using cargo bitbake. Writing yocto recipes manually for [...]
Have you ever imagined what happens when you press the Power ON button on your PC? How does the system boot after hitting the Power ON and all the components involved in the process? No? Let’s see this now! Bootloaders are the first software to run when a device powers [...]
In a Linux-based system, device drivers are critical components that enable the operating system to communicate with hardware peripherals. Whether it’s a keyboard, an I2C sensor, or a custom FPGA, a device driver ensures seamless interaction between software and physical devices. This document serves as a foundational guide to understanding [...]
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 [...]

Today’s automotive industry is completely dependent on microprocessors for controlling every operation in cars. The microprocessor controls the main user interface which then sends commands to small, connected microcontrollers to control different peripherals known as ECU. Therefore, the integrity and security of car firmware hold great importance for automotive manufacturers. [...]
