Arm-Linux-Eabi and arm-None-Eabi
Arm-Linux-Eabi is used to compile armlinuxCode
Arm-None-Eabi does not name the operating system. It can be Linux or VxWorks. Arm-None-Eabi does not contain special macros such as _ Linux, therefore, the Linux kernel cannot be co
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

the difference of the functional emphasis.such as microcontroller and low-end arm (such as M3), more rigorous parlance should be called microcontroller or MCU (Micro control Unit), Chinese is generally called "microcontroller". And the CPU is called the "CPU". There is a big difference between a control and a Process. Microcontrollers do not require a general or powerful computational power, and the emphas
. 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
)
2. Create a script file
# Cd home/downloads/

Therefore, it is a very time-consuming and laborious process to maintain the environment-Toolchain, arm-elf-toochain, mainly because the C library used in the compilation process is different.

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

Master the basic Arm assembly instructions, to write a simple arm assembler program, but also have to master the basic Arm Assembly pseudo operation (Directive). Now let's look at a simple assembler that calls the subroutine to complete the addition operation.

What is the difference between arm-linux-gcc and arm-elf-gcc? embedded basic series-general Linux technology-Linux programming and kernel information. For more information, see the following. How can we explain the differences between arm-linux-gcc and arm-elf-gcc in one sentence?
There are two arm instruction sets and thumb instruction sets.
The arm instruction set is 32-bit long and has the most complete functions. The thumb instruction set is 16-bit long and can implement most of the functions of the arm instruction set.
Thumb instruction set is extremely highCodeDensity (reduced by 30% on average ).

The basic file formats of the arm system are commonly used in ARM-based embedded system development.There are three basic file formats for the arm system:1) bin, flat-board binary format, which is generally used for Directly Writing to flash and loading to the monitor program.2) Elf, executable and linkable format, a common object file format, generally generated

I. Arm has two working states:
(1) arm status. At this time, the processor executes the 32-bit arm command.
(2) thumb status. At this time, the processor executes a 16-bit half-aligned thumb command.
2. Arm processors must be divided into big-end and small-end formats (both arm11 and arm11 are small-end formats)
