1. What is a file system) A file system is a directory structure that includes a disk (including a CD, floppy disk, flash disk, and other storage devices) or a partition. An applicable disk device can contain one or more file systems; to access a file system, you must first mount the file system. To mount the file

For a specific hardware, developed a system, the system is based on computer systems, cutting, suitable for the current hardware. A simplified computer system developed for the purpose of a device. Android is also an embedded system.

Telnet to a Linux host via Windows hostPrerequisite one: From Windows can ping LinuxPremise two: Shut down the Linux firewall, run the command:/etc/init.d/iptables stop(1) Using putty, run the software, enter the IP address (in the Linux system through the ifconfig command query eth0 IP address), the protocol select SSH, and then click Open;After opening, enter the user name and password, you can successful

File transmission through serial ports between the embedded Linux System and the host I think if I want to download something from my PC to the embedded Linux System of the Development Board, many people will first think of using network tools such as TFTP SFTP to download it from the network port. But if the network

Arm Embedded systems often encounter multiple serial port application requirements, and arm chip system native UART number is limited, so it is necessary to extend more interfaces through other high-speed bus. In this paper, Toradex based on the NXPI.MX6D/6Q processor Apalis i.mx6d/q arm computer module, the Linux system through the Exar scheme to expand the 8-ch

Linux embedded configuration real-time operating system 1: The establishment of an embedded linux development environment. To use linux for application development on the development board, you must first establish a development environment. because the development platform is bare metal, the system must be burned and

Fifth annual arm Embedded System national Tour technology lectureARM is the world's leading provider of semiconductor intellectual property (IP), arm in the field of embedded processors has long been recognized, the current industry in more than 90% of embedded products are used in the ARM series of processors.

1. cross-compilation environment: 1) in cross-compilation (E. g: Arm-Linux-GCC) contains. h. When connecting to the app that generates the target board, it will also look for libc. so this library; the directory tree of the Cross-compiling environment should be distinguished from the host. Its own directory tree is usually located, /usr/local/ARM-Linux/bin/* cross-compilation tool *//usr/local/ARM-Linux/include/* header file path *//usr/local/ARM-Linux/lib/* library location */ 2) Path = $ p

Based on Windows Embedded standard and Windows Embedded XP, if you need to add the speech recognition and speech reading functions, you need the support of the following components. Speech Control Panel: You can add a voice control icon to the control panel. You can use this function to select or configure Speech Recognition (Sr-Speech Recognition) or text-to-speech engine (TTS-text speech conversion en

In the near future, some projects of multi-application (multi-task) switching in the command line (Terminal Interface) of the embedded Linux system need to run multiple applications at the same time, but I have no idea about this. I always understand it in a fragmented manner. in the past, I had no progress because I had not summarized it comprehensively. Now, we have learned that many applications (multi-t

The following is an analysis of the volatile keyword that I searched from the Internet ...... A variable defined as volatile means that this variable may be unexpectedly changed, so that the compiler will not assume the value of this variable. Precisely, the optimizer must carefully re-read the value of this variable every time when using this variable, rather than using the backup stored in the register. The following are examples of volatile variables: 1). Hardware registers of parallel de
