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 development data of a company's development Board ti_tools/cgt_a8/ there was a problem with the arm cross-compilation tool in the folder, .. /bin/ld:cannot find-lgcc_sLookup does not find the existence of a dynamic link library libgcc_s.so, so this cross-compilation toolset may not be available or completeDownload New cross-compilation tool, install, problem solvingDownload link (version 4.3.3) Link: http://pan.baidu.com/s/1kTHUJv5sudo tar-jxvf

Naming rulesThe naming convention for the cross-compilation toolchain is:arch [-vendor] [-os] [-(GNU) Eabi] [-GCC] Arch – architecture, such as Arm,mips Vendor – tool chain Provider OS – Target operating system Eabi – Embedded Application Binary interface (Embedded application binary Interface) Attention When there is no vendor, replace with none; If there is no OS support, use none instead With no vendor

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

I have not been able to understand the two cross-compiler exactly what the problem, deliberately Google, summed up as follows, hoping to help the road and I have the same confused brother .... I. What is ABI and Eabi1) ABI: Binary Application Interface (application binary Interface (ABI) for the ARM Architecture)In computers, applying a binary interface describes a low-level interface between an application (or other type) and an operating system or a

ARM's program status register CPSR reflects the status of the current processor, which contains: 1), 4 condition Code flags (negative (N), 0 (Z), Carry (C), and Overflow (V)); 2), 2 interrupt stop bit, control one type of interrupt respectively; 3), a bit used to indicate the current execution instruction (

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

-2.6.12.0.tar.bz2Ftp.gnu.org Gdb6.5.tar.bz2 3. Crosstoo Installation Steps 1. 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

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,

EmbeddedLinux arm Compilation (vii)--C language and arm Assembly mixed programming in the development of embedded system, the main programming language currently used is C and assembly. In large-scale embedded software, such as the OS, most of the code is written in C, mainly because C language structure is better, easy to understand, and there are a large number of support libraries. However , many places

In ARM-based embedded system development, there are two GCC tool chains that often use cross-Compilation:The main difference between ARM-Linux-* and arm-elf-* is that they use different C-library files. Arm-Linux-* useWhile arm-elf-* generally uses uclibc/UC-libc or RedHat f

ARM microprocessor instruction set Overview The arm instruction set is load/storage-type. That is to say, the instruction set can only process the data in the register, and the processing results must be put back into the register, access to the system memory requires special loading/storage commands. ARM microprocessor instruction sets can be divided into six c
