Embedded Linux System Overview, Know about Linux Kernel and Libraries and Utilities for Embedded Applications

Embedded system is meant for a selected purpose. The system gains its name from the very fact that the software is embedded into it for a specific application — an electronic system that features a computer software that's embedded during a hardware . 

A hardware platform is usually a microcontroller or processor during which the program is dumped.

Embedded systems are often found in additional and more devices. Linux as a free OS is additionally becoming more and more important in embedded applications.

The Linux kernel may be a small and special code which is that the core component of Linux OS and is an intermediary layer between the hardware and therefore the software. Its purpose is to pass application requests to the hardware and to act as a low-level driver to deal with the devices and components of the system.

It is fully developed in C language and filing system architecture. Moreover, it's different blocks which manage various operations.

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

Linux is that the OS of choice for several embedded systems like media players, tablets, smartphones and PDAs.

Linux is preferred thanks to its low cost, simple customization and therefore the incontrovertible fact that it's already been ported to custom-purpose microprocessors.

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

The future of embedded Linux systems would seem to get on the upswing. Embedded Linux consistently ranks among the highest operating systems utilized in embedded system design. 

Moreover, with the rise of large-scale connectivity in the Internet of Things (IoT), the ability of Linux to play multiple roles is critical to supporting the various needs of each layer of the IoT application hierarchy. 

Advantages of Embedded Linux:

Compared with proprietary embedded operating systems, the advantages of embedded Linux include software, development and support of multiple vendors. In addition, there are no royalties or license fees.

Additionally, the embedded Linux system is taken into account a stable kernel with the power to read, modify and redistribute the ASCII text file

Disadvantages of Embedded Linux:

Technical disadvantages include relatively large memory footprint (kernel and root file system), complexity of user mode and kernel mode memory access, and complex device driver frameworks. 

The Embedded Linux System Overview training gives you a deep understanding of the Linux kernel and embedded application libraries and utilities.
