hardware selection of the system. A good architecture is the key to successful design. In this step, you often need to select the main chip, determine the RTOS, determine the programming language, and select the development environment (the programming language and development environment are also determined when determining the RTOS) determine test tools and other auxiliary devices. Hardware/software col

1. PrefaceConfiguring and compiling an appropriate GNU Toolchain is relatively complex and requires fine-grained operations, including the dependencies you need on different repositories, their respective tasks, and a better understanding of the different versions of the repositories, which is a tedious task.2. Some terms and names that need to be understood before making1) Build: The compilation system that you use to compile your toolchain.2) Host: The cross-compiler tool chain runs on the hos

This article describes in detail a monitoring method that uses the ptrace system call to implement process communication within the embedded system, and provides corresponding implementation solutions. LinuxInptraceSystem calling is the key to monitoring inter-process communication.ptraceIt provides us with a way to observe and control other processes. ExploitationptraceWe can intercept all system calls of running processes. Interception mean

This section describes the implementation of Microwindows in an embedded system-general Linux technology-Linux programming and kernel information. For more information, see the following section. Preface At present, with the rapid development of various handheld, wireless and embedded devices, the corresponding software and hardware design has also undergone gre

The linux basics needed for Embedded Systems-general Linux technology-Linux programming and kernel information. The following is a detailed description. I just got started with embedded systems and watched five videos today. What makes me feel the most inadequate is my lack

environment starts. After the C environment is started, start_kernel () is run, which initializes the kernel high-level functions, mount the root file system and start the initial process.The first CPU instruction is obtained from an address specified by the manufacturer. This address is usually a fixed storage device, Rom or flash chip. The above software is usedBootstrap. Many Linux embedded systems use

Article Title: some practical suggestions for studying embedded Linux systems. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. It is very popular to learn how to develop and transpl

connectors, compilers, and other tools for target files and files. (2) GCC GCC (GNU Compiler Collection) is an advanced language compiler in Linux. It not only supports C/C ++ compilation, but also supports programming languages such as Fortran, Java, and Ada. (3) glibc Provides C libraries for system calls and basic functions, such as open, malloc, and printf. All C Programs on Linux must be connected to the glibc library during compilation. If it i

Currently, storage modules are indispensable in the development and design of various embedded systems. Nor and NAND are two major non-loss flash technologies on the market. Nor-flash memory has a small capacity and a low write speed. However, due to its fast random reading speed, it is often used in the storage of program code in embedded
