System TutorialLINUXThe main features of the embedded Linux kernel operating system are as followsThe main features of the embedded Linux kernel operating system are as follows
The control core IMX6Q microprocessor selected for this design supports the types of embedded operating systems including WindowsCE, VxWorks and embedded Linux systems.
Moreover, WindowsCE takes up a lot of resources, needs to run a large video memory, and the program running efficiency is low, so it is not suitable for the hardware resource platform selected for this design;
Vxworks system requires payment, and resource openness is low
, the cost is too high and it is more suitable for commercial systems; while the source code of the embedded Linux system is open linux 0.01 kernel analysis and operating system design, which is highly portable and tailorable.
It has a large number of reference materials and mature development tools, and the system program is highly efficient, stable and safe, and supports a wide variety of equipment. Therefore, the software system platform designed this time uses embedded Linux as the operating system of the control device.
The operating system with the embedded Linux kernel as the core has the following characteristics:
(1)Openness
The source code of the Linux operating system complies with the GPL open source plan, complies with world standards and specifications, and is convenient for development and use.
(2)Multiple users
The system kernel resources of the Linux operating system allow multiple users to use linux site:infoq.cn. Each user has specific permissions for their own resources without affecting each other.
(3)Multi-tasking
The Linux operating system can run multiple programs at the same time, and each program is independent of each other. Each process has equal access to processor resources.
(4)Portability
Linux operating system is a portable operating system that can run in any environment and on any platform from microcomputers to small computers.
(5)Modularization
When the Linux operating system is running, programs can be loaded according to the needs of the system without restarting the system. Linux modularization greatly enhances the tailorability and flexibility of Linux.
The embedded Linux system consists of the bootloader, Linux kernel and root file system. Without any of these, the system will fail to start normally.
The job of the bootloader is to initialize some hardware resourceslinux 0.01 kernel analysis and operating system design. It boots the system kernel to start normally. It is the first program executed after the embedded Linux system is powered on. linux Download the tool and its mission is over after the kernel is started.
The Linux kernel is mainly composed of five main subsystems: memory management, process management, inter-process communication, virtual file system and network system. It is responsible for providing a running platform for user space applications.
The main component of the kernel source code is the driver, which provides a channel for user space applications to exchange information with the hardware platform. When the application function program wants to use the hardware, it only needs to call the file represented by the driver to complete the hardware operation. and use.
The root file system is a special file system. It is the first file system mounted after the kernel is started. It stores the processes and functions to be implemented after the kernel is started, as well as some system configuration files and script commands.

What are Linux operations?Apr 13, 2025 am 12:20 AMThe core of the Linux operating system is its command line interface, which can perform various operations through the command line. 1. File and directory operations use ls, cd, mkdir, rm and other commands to manage files and directories. 2. User and permission management ensures system security and resource allocation through useradd, passwd, chmod and other commands. 3. Process management uses ps, kill and other commands to monitor and control system processes. 4. Network operations include ping, ifconfig, ssh and other commands to configure and manage network connections. 5. System monitoring and maintenance use commands such as top, df, du to understand the system's operating status and resource usage.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
