In the development of ARM-based embedded systems, there are usually two types of GCC tool chains that use cross-Compilation: Arm-Linux-* andArm-elf-*, the main difference between the two lies in the use of different C library files. Arm-Linux-* uses GNU glibc, while arm-elf-* generally usesUclibc/UC-libc or newlib. gli

PART1 Environment Building and tool installation 1.1 setting up a cross-compilation environmentTo install the relevant compilation tools:sudo Install Gcc-arm-linux-gnueabiHere I use the Gcc-arm-linux-gnueabi series tools that are included in the Ubuntu system source and have the following tools after installation:Arm-linux-gnueabi-addr2line arm-linux-gnueabi-GCC

Original URL: http://www.cnblogs.com/muyun/p/3370996.htmlFirst, install the ARM-LINUX-GCC tool chainOnly one command is required:　　sudo apt-get install gcc-arm-linux-gnueabiThe premise is that your Ubuntu system version is the latest version supported by the official website, if not, please upgrade. Execute the above command.Ii. Use of tool chainsAttention! You cannot use GCC commands to summon it here. Its

Cortex-m3 and ARM11 differences:The CORTEX-M3 Architecture (ARMV7) is higher than the ARM11 (ARMV6) version, but performance is less than ARM11.But the CORTEX-M series of chips in the application of the main low-end (equivalent to a si

Analysis on the Relationship between GCC, arm-Linux-GCC, and arm-elf-gcc Embedded Development Exchange Group 280352802, welcome to join!1. Introduction to GCC The GNU Compiler Collection, usually GCC for short, is a set of compilers developed by GNU. Why is it an editor set rather than a compiler? This is because it not only supports C language compilation, but also supports many languages such as C ++, Ada

What is the difference between arm-elf and arm-linux-general Linux technology-Linux programming and kernel information? For more information, see the following. The following are the differences between the two cross-compilation environments: These two cross environments have been used In the development of ARM-based embedded systems, there are often two types

I. INTRODUCTION of GCC:The GNU Compiler Collection, often referred to as GCC, is a set of compilers developed by GNU, and why is it an editor set instead of a compiler? That's because it not only supports C language compilation, but also supports C + +, Ada, Objective C and many other languages. In addition, GCC support for the hardware platform can be ubiquitous, it not only supports the X86 processor architecture, but also supports arm, Motorola 680

The most commonly used build version is arm-linux-gcc-3.4.1 and arm-linux-3.3.2, now embedded development basically use these, 3.4.1 is used to compile 2.6 kernel, and 3.3.2 is commonly used to compile busybox, if the compilation version does not work well with bootloader (u-boot), errors may occur. Therefore, you must select a compiled version. If this version does not work, try other versions,

thumb Instruction Set and can execute all existing code written for earlier processors. Using a forward conversion method, the user code written for ARM cortex-M series Processors can be fully compatible with arm cortex-R series Processors. Arm cortex-M series system code (such as real-time operating systems) can be easily transplanted to systems based on

Enterprise-level open-source software vendor RedHat is paying close attention to the development of servers using 64-bit ARM processors. By improving enterprise-level features, it will soon begin to adopt the 64-bit ARM platform in the data center. Ldquo; although you have not seen our commercial products on the market today, we are building leading capabilities. From top to bottom for the upcoming 64-bit

Label: style blog HTTP ar strong SP data Div 2014 We have been studying arm recently. Speaking of arm, we first thought of Samsung, Qualcomm, and other companies. These companies make CPUs. In fact, arm is also a company, however, it provides the core logic circuit, and its way of making money is win-win with other companies! How many chips do you sell? I just

Prepare resource files First, download the required resource files from the Internet, put these toolkit files under the newly created $ home/downloads directory, and then decompress crosstool-0.43.tar.gz in the $ home/downloadsdirectory. The command is as follows: # Cd/home/zhoug/downloads (note $ home =/home/zhoug) # Tar-xzvf crosstool-0.42.tar.gz ( For the tar.bz2 file, decompress the command # Tar-xjvf xxx.tar.bz2

Introduction to ARM assembly (I)-knowledge preparation and arm preparation I read the prose of Shi Tiesheng, and it involves the memories that I have never experienced in my life, just like the sad treasure travel in the thick soil of Huangshan in the north, those who believe in the same sunshine and devout people in the sun. I think there will be a long trip, in the broken time and the road, to observe all
