Abstract: The portability of Embedded Linux allows us to see it on various electronic products. Linux boot processes vary for processors of different architectures. This article takes the S3C2410 ARM processor as an example to analyze the execution

  1. Linux kernel Startup Process OverviewAn embedded Linux system can be divided into four parts: Boot Loader, Linux kernel, file system, and application. Bootloader is the first code executed after the system is started or reset. It is mainly used

This article introduces in detail the concept of boot loader, which is based on the OS boot loader in the embedded system, The main tasks of software design and the structure framework. 1. Introduction Running GNU/Linux systems on dedicated

File System of embedded devices The system needs a method for storing and retrieving information in a structured format, which requires the participation of the file system. Ramdisk (see references) is a mechanism for creating and mounting a file

Introduction in Linux, there is a special feature-initializing the memory disk initrd (initial RAM disk) technology, and the kernel supports compressed file system images. With these two features, we can enable Linux to initialize memory disks from

############ Review embedded Linux application ############Embedded Linux applications:I. Embedded summary, basic concepts:1. GPL: The same as GPL for the database connected to it;Lgpl: lgpl is required only when it is modified; In general, GPL is

The following two articles are very good articles on the RAMDisk file system in the ARM9 forumToday did a test, let Linux2.6.29.4 from the RAMDisk root file system to start a successful, summed up.It involves more content, a lot of things no longer

This article was reproduced from: https://www.ibm.com/developerworks/cn/linux/l-btloader/In this paper, the concept of ――boot Loader, the main tasks of software design and the structure framework of the OS Launcher loader based on embedded system

Memory addressingMemory address: Logical Address: Segment + offset compositionLinear address: Can be used to express the address of 4GB (also called virtual address)Physical Address: Used for memory chip-level memory unit addressing. They correspond

Memory UsageOn Linux, there is commands for almost everything, because the GUI might is always available. When working on servers only the shell access is available and everything have to be do from these commands. So today we shall is checking the
