Embedded Linux System Overview Training

Embedded systems can be found in more and more devices. Linux as a free operating system is also becoming more and more important in embedded applications.

The Linux kernel is a small and special code which is the core component of Linux OS and is an intermediary layer between the hardware and the software. Its purpose is to pass application requests to the hardware and to act as a low-level driver to address the devices and components of the system. It is fully developed in C language and file system architecture. Moreover, it has different blocks which manage various operations.

The Linux kernel can run on many different computer architectures, most of which are quite popular in the embedded world.  All of the base packages allowing the OS to perform the basic tasks are suitable for cross-compilation, therefore Linux can be as pervasive as microcontrollers and Systems on Chip (SoCs).

Linux is the operating system of choice for many embedded systems such as media players, tablets, smartphones and PDAs. Linux is preferred due to its low cost, ease of customization and the fact that it has already been ported to custom-purpose microprocessors.

Google’s Android, for example, is based on a modified Linux kernel and released under an open source license. This allows manufacturers to modify it to suit their particular hardware. Maemo, BusyBox, Mobilinux and Debian are other examples of embedded Linux open-source operating systems.

The advantages of embedded Linux over proprietary embedded operating systems include multiple suppliers for software, development and support. Also, there’re are no royalties or licensing fees.

Additionally, the embedded Linux system is considered a stable kernel with the ability to read, modify and redistribute the source code.

The technical disadvantages include a comparatively large memory footprint (kernel and root filesystem), complexities of user mode and kernel mode memory access and a complex device drivers framework.

The future of embedded Linux systems would appear to be on the upswing. Embedded Linux consistently ranks among the top operating systems used in embedded system design. And, with the mushrooming of the Internet of Things (IoT) massive connectivity, the ability of Linux to serve multiple roles should prove vital in supporting diverse needs at each layer of the IoT application hierarchy.
