arm-linux notes 3:arm-linux pc File Transfer method Summary (4 most common methods)1 transferring files using a serial terminal2 Transferring files using FTP3 Transferring Files using NFS4 Using a U-disk copyThe advantage of the serial port is that the method is simple, does not need too much configuration, does not need to join the network, but sends the data the speed is relatively slow, does not apply in

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. 1.

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

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

When compiling the Linux kernel, the first thing to do is to modify the makefile file in the top-level directory of the kernel source, change the Arch = $ (subarch) to arch? = arm, and change the cross_compile? = to cross_compile? = arm- LINUX-GCC, or not modified, the arch and Cross_compile values are passed through the command line. Then in the Linux kernel source directory, execute make menuconfig, then

Windows Azure Platform Family of articles Catalog　　This article is more content, please read carefully, thank you!In the first few chapters, we did the preparatory work:1. Create Arm resouce Group, called Leiresourcegroup2. Create Arm Storage account, called Leistorageaccount3. Create arm Virtual Network, called LeiarmvnetIn this chapter, I will show you how to c

Examples of C and assembly languages or programming in ARM, and explanations of arm instances1. inline assembly Notes for Embedded Assembly in C language: You cannot assign values directly to the PC register. B or BL commands must be used for program redirection. Do not use overly complex C expressions when using physical registers, avoid physical register conflicts. R12 and R13 may be used by the compiler

Arm learning-Summary of bit operations and arm learning Summary In the process of learning arm, the sensory register basically does not provide bitwise operations, but the overall operation,The overall operation is to note that when assigning a value to a specific bit, it does not affect other places. It does not look simple,In fact, the overall operation is ski

then select the appropriate subscription information and location for the Azure datacenter.　　　　Note here : the Azure Resource group can only belong to one region. But the resources in the Azure Resource group can be in other datacenters.For example, I created a new leiresourcegroup in China East. Under this resource group, you can create a virtual machine in China.6. Once created, the results are displayed, such as:　　================================= I am the delimiter =========================

. 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/

clear, you can visit the official Intel in the CSDN blog. a summary of the performance in the project is: If the project contains only Armeabi, it can be run on all Android devices; If the project contains only armeabi-v7a, it can be run in addition to the Armeabi architecture; If the project contains only x86, then the armeabi architecture and armeabi-v7a Android devices will not work; if both Armeabi, armeabi-v7a and x86 are included, all devices can be run, and the program will load diffe

Source: Zhou licong ppt) Addressing type classificationThe addressing method is to find the actual operand address based on the address code field given in the instruction. The ARM processor has nine basic addressing methods.1. Register addressing; 2. Immediate addressing;3. Register shift addressing; 4. Register indirect addressing;5. base address addressing; 6. Multi-register addressing;7. Stack addressing; 8. Block copy addressing;9. Relative addre

How does ARM enable the diagnostic extension of LAD2.3 and arm enables lad2.3? Linux Azure Diagnostic (Glad) extensions are now available in version 3.0, but in Azure China, the latest version is 2.3. Although the Azure portal provides a simple operating version to enable diagnostic extension for Linux virtual machines, users may also ask how to use PowerShell and other tools to set up. Use is not supported

In the past two days, I have tried to build the stm32 development environment of eclipse + GNU arm Eclipse plug-in + sourcery g ++ Lite Edition for ARM + opencd + jlink, I also use Keil very well, mainly because I recently worked on a project to make it impossible to use a commercial environment. I searched almost all the information on the Internet and found that there was very little information. I sorted
