Introduction
What is Docker
Docker is an open source project that was born in early 2013 and was originally an amateur project within the DotCloud company. It is based on Google's launch of the Go language implementation. The project later joined the Linux Foundation and complied with the Apache 2.0 protocol, and the project code was maintained on GitHub.

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

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
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 ).

In this article we will use Docker's existing cloud image Training/webapp to publish a simple Python web program that outputs Hello World in a browser.The test environment for this article is Docker under Windows7, and use cases are based on official document use cases.one: From running a simple Python Web

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.

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
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
