The Comprehensive Guide to Embedded Linux（嵌入式linux手册）

Embedded Linux is a reliable, secure and customizable operating system that, when implemented, provides an open source Unix-like platform with immense opportunity for processor optimization. It has emerged as one of the leading operating systems for use in embedded systems and promises to be an indispensable technology in the coming years.

In this comprehensive guide, we will explain the fundamentals of Embedded Linux, the process of getting it up and running and teach you how to customize your system to your own particular preferences.

Before we get started, let’s discuss the basics. Embedded Linux is a lightweight implementation of the Linux operating system that is extremely resource-efficient and designed for use in embedded systems, such as consumer electronics and other devices with limited memory and storage. It is customizable, allowing developers to select from a range of packages, tools and libraries to customize the system according to the target platform’s particular requirements.

Installing a Linux-based operating system on an embedded system requires several steps. For starters, you will need to select a supported distribution and consider your target platform. The board manufacturer typically provides a supported OS and bootloader.

Next, you have to install the operating system on your device. To do this, you will need to download the source code of the supported distribution and compile it. You may also need to edit the bootloader’s configuration. After the system is successfully compiled, you will be able to connect the target system to the power source and boot it.

Once the system is up and running, there are several tasks to be done to customize it. You can run a number of command line utilities such as “ls” to check the directory structure, “cp” to copy files and “mount” to mount the new file system to the board. You can also use a number of GUI-based tools to configure the system or modify settings.

Finally, you can develop your own programs and add them to the Linux system. This can be achieved by writing code in any open source language such as C or Python, compiling it, and then running the resulting executable on the device.

Embedded Linux is a powerful and versatile operating system that provides a highly customizable platform for embedded system developers. By understanding the fundamentals and following the installation steps, developers can create systems tailored to their own specific applications. This comprehensive guide has provided an overview of the process, we hope it helps to get you started.
