ARM assembly instructions are many, but the real use is not a lot, but also need to seriously think about less. More useful is MOV B BL LDR STR or through the specific assembly code to learn it. @ Disable Watch dog timer mov r1, #0x53000000// immediate number addressing mode mov r2, #0x0 str R2, [R1]MOV There is nothing to say, as long as the master a few ways to address, and ARM to address the way i

1. Software InstallationStep 1: Open the virtual machine, create the/usr/local/arm folder under/usr/local/(General user customization program put here)Step 2: First get the installation package from Windows to Linux. You can use a shared folder, or you can use Samba, or you can cuteftp.Step 3: Unzip. TAR-JXVF arm-2009q3.tar.bz2To the installation directory of the real application (aka/usr/local/

1. Introduction This document describes how to build ARM Trusted Firmware and run it with a tested set of other software components using Defined configurations on the Juno arm development platform and ARM Fixed Virtual Platform (FVP) models. It is possible-to-use other software components, configurations and platforms but that's outside the scope of this Docume

This is the graduation brother's Virgo blog, I hope you do not spray!!!Due to the needs of the laboratory project, graduating brother began to study Python at 9 o ' Night (2014/11/05). Oneself a bit obsessive-compulsive disorder, install what software all request new, so give oneself windows to install a Python3.3 (also bury a thunder for oneself). Before I installed Python-2.7.3 on a Linux machine, I didn't think much of it, thinking that the Python Premium version was backwards compatible. So

analysis of embedded Linux interview (I.)--ARM Part II 1. describe how the embedded ROM-based operation is based on RAM What is the difference between the operating mode. RAM-based operation: the hard disk and other media need to be loaded into the RAM, loading process generally has relocation operations;Rom based: no above operation.ROM-based: Slower than ram-based, because there will be a variable, part of the code, such as moving from memory (hard

The functions of the Arm-linux tool are as follows: Arm-linux-addr2lineConverts the program address to the file name and line number. Give it an address and an executable file name on the command line, and it uses the debug information of the executable file to indicate which file and line number is on the given address. Arm-linux-arCreate, modify and extract arc

If you are a student of electronic communication or are engaged in embedded electronic communication work engineer, assistant engineer, intern, handyman, I think you have a complex fear of the assembly, and even this fear is the University of learning "microcomputer technology" began. But for the author's superficial work experience, it seems that if you can master or step back and understand the assembly, then you can enjoy the fun as a hardware programmer at the bottom. Imagine using the assem
