VAct Technologies

Embedded Linux & Yocto Project

Linux is an open-source Unix like Operating Systems based on Linux Kernel. Linux is typically packaged in Linux Distribution. Distribution include Linux Kernel and supporting system software and Libraries many of which are provided by GNU Project. Many Linux Distribution use the word “Linux” in their name but the foundation uses the name “GNU/Linux”.
Linux was originally developed for personal computers based on the Intel x86 architecture, but has since been ported to more platforms than any other operating system. Because of the dominance of the Linux-based Android on smartphones, Linux also has the largest installed base of all general-purpose operating systems.
Linux also runs on embedded systems, i.e. devices whose operating system is typically built into the firmware and is highly tailored to the system. This includes routers, automation controls, smart home technology, televisions (Samsung and LG Smart TVs use Tizen and WebOS, respectively), automobiles (for example, Tesla, Audi, Mercedes-Benz, Hyundai, and Toyota all rely on Linux), digital video recorders, video game consoles, and smartwatches. The Falcon 9’s and the Dragon 2’s avionics use a customized version of Linux.
Linux is one of the most prominent examples of free and open-source software collaboration. The source code may be used, modified and distributed commercially or non-commercially by anyone under the terms of its respective licenses.

Foundation of Embedded Linux

Embedded Linux is one of the types of OS in Linux/Kernel which is used of implementing Operating Systems in various platform and is free to use and also can be customized and also designed to be installed and used with Embedded device for developing constrained applications. It is the compact version of Linux that offers features and services in line with the operating and application requirements of an Embedded System.
Embedded Linux, even it is same as Linux kernel, it is quite different from the standard Linux OS. Embedded Linux is specifically customized for embedded systems. Therefore, it is having a much smaller size, requires less processing power and has minimal features. Based on the requirements of the underlying embedded system, the Linux kernel is modified and optimized as an embedded Linux version. Such an instance of Linux can only run device-specific purpose-built applications. Android OS is a type of embedded Linux, customized to be used on smartphones. Other devices on which embedded Linux is used include:
If you are the one, who has the passion to develop an Operating Systems on your own, V Act Technologies can guide you from the scratch and you can able to complete it within the shorter period of time.
