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.

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

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

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

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

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)

(9) Call the decompress_kernel () function of the file Misc. C to decompress the kernel at the end of the cache.(After the R2 address ). The register values are changed as follows:R0 indicates the size of the extracted kernel.R4 is the address when the kernel is executedR5 is the start address of the kernel after decompression.R6 is the CPU type value (processor ID)R7 is the system type value (Architecture ID)(10) after the reloc_start code is copied to the kernel (R5 + R0), the cache is cleared

Create an arm-linux cross-compiling environment: whether to compile an arm-glib library. -- Linux general technology-Linux programming and kernel information. For details, see the following. Create an arm-linux cross-compiling environment: 1. Download the compilation tool: arm-linux-gcc instead of using the source cod

Windows Azure Platform Family of articles Catalog　　When we use ARM to create resources, we first need to identify which Azure services support arm mode.For details, we can refer to the connection: https://azure.microsoft.com/en-us/documentation/articles/resource-manager-supported-services/With a special emphasis on azure virtual machine VMS, Azure VMs are divided into two modes: ASM and arm.We are in the ol
