Overview build a kernel that is typically configured first and then compiled. This is the example of building the NEXUS5 kernel, codenamed Hammerhead. Configuration The usual approach is based on the vendor-provisioned configuration, which is configured to suit your needs. Command: Make Arch=arm Hammerhead_defconfig After execution, the "arch/arm/configs/hammerhead_de

　First, the file to be prepared is arm-2009q3.tar.bz2 (extract code: 619b)After that, we need to put this file in a shared folder before it can be used on Linux in the virtual machine.1. Let's start with the installation of VMware Tools (this is installed to use shared folders) (I'm using CentOS 6.3)(1) First, at the top of the toolbar, we open the virtual machine--Install VMware Tools (because I have installed VMware tools, so the display is reinstal

Install SDK 1.Hi3531 SDK package location In the "Hi3531_V100R001 *** / 01.software/board" directory, you can see a Hi3531_SDK_Vx.x.x.x.tgz file, This file is the Hi3531 software development kit. 2.Unzip SDK package On a Linux server (or a major Linux distribution on a PC with Linux installed), use the command: tar -zxf Hi3531_SDK_Vx.x.x.x.tgz, Unzip the file to get a Hi3531_SDK_Vx.x.x.x directory. 3.Expand SDK package contents Return to the Hi3531_SDK_Vx.x.x.x directory and run ./sdk.unpack

I. Introduction to DMA As a technology used to transmit data between CPUs and peripherals, DMA is widely used in various computer architectures. Its biggest advantage is that it can transmit data from memory to peripherals without CPU interference. This article describes how to operate the DMA controller in s5pc100. ExamplesCodeAll are verified on the fs_s5pc100 platform. On the far-sighted fs_s5pc100 platform of Huaqing, The pl330 DMA controller enables multiple DMA transmission modes, includi

Next we will talk about ARM. The development tools of ARM application software depend on different functions, software compilation, assembly software, link software, de

Overview I think this is meaningless. The biggest feature of an embedded system is "embedding". That is to say, your control system is embedded in your control object, so the first thing is to obey the needs and features of objects. What is the basis for separation from object null? Each MCU has its own value, and each user's choice has its own rationale. Starting from aVR, It is a selling point of a single clock period command, compared with the classic 51 with the 12 clock at that time, and b

(1) Introduction to cross-Compiler A compilation program running in a computer environment can compile the code running in another environment. This compilation process is called cross-compilation. to put it simply, it is to generate executable code on another platform.(2) architecture and Operating System (1) common architectures include arm and x86 architectures. (2) common operating systems include Linux and Windows. (3) the same architecture can r

The first part of Linux under the ARM assembly syntaxAlthough it is convenient to write programs in C or C + + under Linux, the Assembly source program is used for the most basic initialization of the system, such as initializing the stack pointer, setting the page table, and manipulating arm's coprocessor. After initialization is completed, you can jump to C code execution. It should be noted that the GNU assembler follows the ATT assembly syntax and

Learn embedded well, you have to do more hands-on, more practice. To get started, configure your own development environment and migrate the kernel. The development environment does not say that the porting kernel will have to compile the kernel first. You have to have a compiler. Because the architecture of arm CPUs is not the same as x86. The usual practice is to use the arm cross compiler in the x86 deve

MPlayer 1.0 has brought most of the decoding libraries, such as FFmpeg, But the audio library that comes with it is very bad in s3c2440. It's good to use Libmad. So the simplest transplant for mplayer in Arm-linux only needs to be ported. The character interface is played after the transplant. However, the full version requires the following libraries. If subtitles support is required. The FreeType library needs to be ported. Support JPG skins need li
