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,

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

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

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

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

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

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

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
