In the potentially growing world of embedded systems, data integrity has become a big problem. According to a survey, 94% of companies manufacturing embedded systems reported a cyberattack at least once in the last 2 years. Security Weaknesses in your systems can lead to many vulnerabilities. Secure boot is one [...]
In the present world, every device is smart and controllable through the Internet. Therefore, companies spend a lot of money on ensuring the network security of embedded devices. But embedded devices are still vulnerable to attacks from different sources. Have you wondered why and how? The answer is simple. Network [...]
Kernel fitImage signing is an important step in embedded secure boot. In this technique, a public-private key pair is generated by OpenSSL. The private key is used to sign the kernel fitImage. The public key is placed in the device tree of the bootloader (uboot or barebox) which is used [...]
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 [...]
The Cyber Resilience Act (CRA) has become a security baseline for selling all the embedded products involving Hardware, software and networking connectivity in EU Market. According to this act, any embedded products not fulfilling CRA compliance can’t be sold in European markets from 2027. Let’s see what makes an embedded [...]
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 [...]
