Ubuntu has been installed in the previous step, and the language pack is updated so that you can start next.
1. Install ARM-LINUX-GCC, whether you are downloading from the Internet, or the development of the CD inside, can be, the version is not limited, my is arm-linux-gcc-4.3.2.
Enter ARM-LINUX-GCC installation package directory, my location is in/home/cfan/t
1. Introduction
This document describes how to build ARM Trusted Firmware and run it with a tested set of other software components using Defined configurations on the Juno arm development platform and ARM Fixed Virtual Platform (FVP) models. It is possible-to-use other software components, configurations and platforms but that's outside the scope of this Docume
This is the graduation brother's Virgo blog, I hope you do not spray!!!Due to the needs of the laboratory project, graduating brother began to study Python at 9 o ' Night (2014/11/05). Oneself a bit obsessive-compulsive disorder, install what software all request new, so give oneself windows to install a Python3.3 (also bury a thunder for oneself). Before I installed Python-2.7.3 on a Linux machine, I didn't think much of it, thinking that the Python Premium version was backwards compatible. So
Abstract
ARM servers are becoming increasingly common, making server technologies such as virtualization for arm of growing Importa nCE. We present the study (1) of ARM virtualization performance on server hardware, including multi-core measurements of Two popular ARM and x86 hypervisors, KVM and Xen. We show how
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

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/
Eabi (Embedded Application binary Interface), binary interface of embedded applications.
AbiDefinition
Abi describes the underlying interfaces between applications and the operating system, between applications and libraries, and between application components. Abi allows compiled target code to run in a system compatible with Abi without any changes.

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

-Vic in armA:If the code is run in the On-chip RAM and the application needs to call the interrupt, the interrupt vector must be re-mapped to the flash Address 0x0. This is done because all the abnormal vectors are located at the address.0x0 and above. This is achieved by configuring the register memmap (in the system control module) to the user Ram mode. User code is connected to enable the interrupted vector table to be loaded0X4000 0000.
