Pre-learning some of the 51 single-chip computer part of the knowledge, just to a single-chip microcomputer has a preliminary understanding, and the most basic operation, did a certain thinking turn, the work principle of the hardware has an intuitive feeling and experience, under the turn to the liunx of an entry-level learning, hope can from the most basic learning, The most basic content of Linux to grasp the solid, the more basic knowledge of the
When I read the embedded Linux LED driver today
The driver implementation part is clear.
But the paths of several header files really confuse me. the Linux 2.6.13 file is organized as follows:
The header file is as follows:
#include
But I cannot find the ASM folder corresponding to the arm, or the corresponding directory does not correspond to the s3c24xx folder.
Later, I accidentally read an article a

I have explained the basic concepts of Linux in this series of articles. The Linux operating system inherits from UNIX. An operating system is a set of software for controlling and using computers. UN
Linux Process Scheduling analysis and linux scheduling AnalysisOverview
Multi-process scheduling is essential for the operating system. Some people say that process scheduling is the most important part of the operating system. I think this is an absolute saying, just as many people say that "a function is XX times more efficient than a function", it is out of the actual environment, these conclusions are o
displayed and Linux and an optional initial RAM disk (temporary root file system) are loaded into memory. When the image is loaded, the second stage of the bootloader gives control to the kernel image and the kernel can decompress and initialize it. During this phase, the second stage of the bootloader detects the system hardware, enumerates the system-linked hardware devices, mounts the root device, and then loads the necessary kernel modules. After

A) Windows is a multi-root file system with one or more hard disks physically divided into C, D, and E ...... Disk. Each disk is a tree. Linux is a single file system, regardless of the CDE disk. Multiple h
We usually use Linux grub or lilo to boot the partitions, or we can use Windows

The most traditional Disk File System in Linux is EXT2 (of course, it has now been upgraded to EXT4). This chapter mainly introduces the disk file system in Linux, this article focuses on the Linux
Introduction to dual Linux and multi-Linux installation methods-general Linux technology-Linux technology and application information. For details, refer to the following section. The two installation methods are provided in the same principle.

1. Divide the hard disk into four (or less) Primary partitions
Software package management tools under Linux
Linux Software installation can be done in two ways, one is directly with the package management tool installed, and another through the compilation of source installation.
1. Types of packagesRed Hat and Fedora: RedHat's earliest release of the personal version of Linux, since the release of Red Hat 9.0,
The basic architecture of Linux is summarized by the following two graphs (two graphs are the same, but the focus is slightly different)From the knowledge, Linux is composed of two parts: User space and kernel space. Kernel space and user space are two different states of program execution, which can transfer from user space to kernel space through system call and hardware interrupt.Due to the different ver
Today's world's popular operating systems have 3 categories,Linux,MacOS and Windows operating system,Linux operating system because of its open source, free, cross-platform, Good interface and other characteristics, by the broad masses of programmers favor!Linux operating system is widely used in the enterprise Server domain, the current network equipment on the
A Objective
Linux has a wealth of source code resources, but most of the code is not compiled properly on Windows platform. These source code resources are not directly available to the Windows platform at all. If you want to use the complete code, you need to do a transplant. Because of the different and other reasons for the C + + library, porting C + + code is a difficult task. This article will use a practical example (Tar) to illustrate how to mi
Although GUI desktops, such as KDE and GNOME, can help users take advantage of Linux features without the functional knowledge of command-line interfaces, they often require more functionality and flexibility. Moreover, familiarity with these commands is still necessary to automate certain functions in the shell script correctly.This article is an "accelerated tutorial" on Linux file commands, which is prov
This section describes what happens when a Linux system boots and shuts down, and should be done correctly. If the correct procedure is not followed, the file may be corrupted or missing.
Boot and Shutdown overview
The process of turning on a computer and causing its operating system to be loaded is called booting. The name comes from a computer pulling itself up to its bootstraps, but the act itself slightly Stic.

To download the Linux kernel, you must go to the official website. The website provides two types of file downloads: one is the complete Linux kernel, and the other is the incremental kernel patch. They are all tar archive packages. Un
I've always been using Ubuntu and Fedora as a starter system, but actually what I really want to recommend is arch, after the previous study, perhaps you have a general understanding of Linux, and now if you want to speed up your pace, maybe you can look at this article.

1. Use the first Aid disk group for maintenanceThe first Aid disk group (also known as the Boot/root Disk group) is an essential tool for system administrators. It allows you to start and run a complete Linux system independently. In fact, there is a complete Linux system on the 2nd disk of the first aid disk group, including the root file system, while the 1th disk holds the bootable kernel. It is easy to
