Why Embedded Linux?
If you are trying to create your own project, developing a kernel from scratch for your hardware is an incredibly challenging process, since it requires deep knowledge of both hardware and code.
You may also have heard of bare-metal tasking kernels (without an operating system) for microcontrollers, such as FreeRTOS, Azure RTOS, RT-Thread, μC/OS, but these choices lack memory management and protection which are critical to building modern applications. Because of this, you may be looking for a more comprehensive solution.
Fortunately, there are many advantages of using embedded Linux on a microprocessor in your embedded applications, such as built-in dynamic memory management and security modules that you might want to consider.
Linux has Extensive Compatibility
Over the years, Linux has grown to support a large variety of CPU architectures, including x86, ARM and PowerPC etc. So, no matter what kind of hardware you are working with, there is a good chance that a Linux kernel already exists for it.
Linux supports nearly all the programming languages and utilities that you need for your embedded system development endeavours. With Linux, you are not restricted to any specific software. If you are dissatisfied with anything, there is a good chance that an alternative is available – or you can be the first in the community to develop it!
Linux is Open Source
Linux, as an open source kernel, allows you to leverage on the work of thousands of developers across the world. By tweaking or directly implementing existing packages, you can get your own applications up and running far more easily and quickly.
The Linux Community is There for You
Got a specific question? No problem! Because Linux is used by so many developers, you not only have their code to count on, but also their experience and knowledge. Simply ask away at one of the many forums available, like linux org.
