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

Mplayer 1.0 already comes with most of the decoding libraries, such as FFMPEG, but the built-in audio library works very poorly in s32440. use libmad instead. therefore, to port mplayer in arm-Linux, you only need to port the two. after transplantation, the character interface is played. the arm version was first run successfully by my student Cheng lei.However, the complete version requires the following l

Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. The following files are used as examples to create an arm-linux cross-compiling environment: 　　 Compiling environment redhat 7.2 or 8.0 Binutils-2

I. Preface Anyone who has learned about ARM embedded knows that in order to make the PC program run on the ARM board, a cross-compilation environment must be established to compile the source code. I will not talk about the basic concepts of the Cross-compilation environment. Here, I mainly write the steps and ideas for creating a cross-compilation environment. My setup process went through four crazy days.

Arm-linux compiler cross tool detailed description arm-linux tool functions are as follows: arm-linux-addr2line program address to convert the file name and line number. In the command line, give it an address and an executable file name, it will use the debugging information of this executable file to point out that the given address is the

The main difference between this article and the previous one is that there is no use of system GMP, MPFR, MPC, Cloog, etc., but using source code to compile. 1. Compile binutils: Unzip the BINUTLS code into the SRC directory and create the Binutil directory in the build directory. Execute in the Build/binutils directory: .. /.. /src/binutils-2.25/configure--prefix=/home/charles/code/build_toolchain/toolchain--with-sysroot=/home/charles/ Code/build_toolchain/toolchain/

systems is limited, generally, you need to create a cross-compiling environment for the target machine on your powerful PC. This is a comprehensive development environment consisting of compilers, connectors, and interpreters. The cross-compilation tool consists of binutils, gcc, and glibc. Sometimes, to reduce the libc library size, you can use other c libraries to replace glibc, such as uClibc, dietlibc, and newlib. Creating a cross-compilation toolchain is quite complicated. If you don't wan

First, let's talk about the development of arm. It can be described as a good one to open the websites of various companies, and embedded recruitment occupies most of the positions of engineers.In the broad sense, there are only a few types of embedded systems: Traditional 51, AVR, and PIC are called embedded microcontroller; arm is an embedded microprocessor; DSP; FPGA.Objectively speaking, DSP requires mo

Arm and realviewEmbedded debugging of arm realview With the development of embedded applications, especially in the field of digital communication and network, it puts forward higher requirements on processor performance. To adapt to this situation, there have been many multi-core structured processors, such as two or more arm or DSP processors. At the same time,

Song Baohua talks about the basic concepts of arm's embedded Linux porting experience 1. IntroductionArm is short for Advanced RISC Machines (a processor of advanced and streamlined command systems). It is a microprocessor intellectual property (IP) Core provided by arm.Arm has been applied in various product markets, including industrial control, consumer electronic products, communication systems, network systems, and wireless systems. ARM-based mic

), Virtual File System (VFS), and network interfaces, the Linux components and their relationships are given: The Linux kernel source code contains multiple directories:(1) arch: hardware-specific kernel code, such as arm, MIPS, and i386;(2) Drivers: contains hardware driver code, such as char, CDROM, SCSI, MTD, etc;(3) include: General header files and specific header files for different platforms, such as asm-i386, ASM-

link functionality. In ARM-LINUX-GCC, this link-mode command has the following basic form $ (cc) -static-wl,-tboot.lds,-map,system.map-nostartfiles-o boot.elf $ (OBJS) CC This is ARM-LINUX-GCC -Wl, -TBOOT.LDS,-MAP,SYSTEM.MAP-WL indicates that subsequent arguments are passed to the linker, and the arguments are separated by commas. -tboot.lds is the specified link script that plans the location

In the embedded development, sometimes need to do the source level debugging, can set breakpoints, step execution, compared to each step printing printf or printk, more friendly. This debugging method is described below. GDB cross-debugging is similar to a Web browser, the local PC for the client, the remote Development Board for the server side, both sides to compile the tool chain uniformly, the version is best consistent. --TARGET Specifies the target cross compiler prefix, such as--target=

Environment: the ARM development board is ok6410, and the host is ubuntu10.04. 1. Preparation: Use the optical disc arm-linux-4.4.1.tar.gz tool to decompress the tool to the/usr/local/ARM directory (Add/usr/local/ARM/bin to the environment variable).

Although it is convenient to use C or C ++ to write programs in Linux, the assembler source program is used for the most basic initialization of the system, such as initializing the stack pointer, setting the page table, and operating the arm coprocessor. After initialization, you can jump to C code execution. Note that the GNU assembler follows att's Assembly syntax and can download the relevant specifications from the GNU website (www.gnu.org. I.
