Embedded Linux development environment and some ideas for embedded entry

<span style= "font-family:arial, Helvetica, Sans-serif; Background-color:rgb (255, 255, 255); " > recently began to learn embedded Linux development, for embedded I am completely novice, but I still want to write something, to the later people to make a reference, let some people less go some detours. </span>

1. Install the basic development environment under host Linux:

$ sudo apt-get install build-essential$ sudo apt-get install bison flex$ sudo apt-get install Manpages-dev

2. Installing the cross-compilation tool chain

As a novice, I suggest that the use of a good tool chain has been made (because I have tried to compile their own, which met with countless wonderful questions, delayed a lot of time, but also a workout for themselves, if there is time I will tidy up the problems of the compilation and then write an article blog)

Create a new directory:

$ mkdir work/tools$ CD Work/tools

Extract:

$ sudo tar xjf arm-linux-gcc-3.4.5-glibc-2.3.6.tar.bz2

Set path:

$ sudo gedit/etc/envrionment

Add Path:work/tools/gcc-3.4.5-glibc-2.3.6/bin

Install ncurses:

Ncurses is a dynamic library that provides functional key definitions, screen drawing, and graphical interactive functions based on text terminals.

We can use it here.

$ sudo arm-linux-gcc-v

To check if the cross-compilation toolchain is configured successfully

In addition, I have some small ideas and suggestions for embedded Linux development:

1. Getting started requires knowledge and skills that are progressively understood:

-------> will use Linux (this is the most basic)

-------> Understanding some of the commands in the cross compiler (ARM-LINUX-GCC, etc.)

-------> Understanding Makefile (Rules, common functions, etc.)

-------> Understanding Arm Assembly Instructions

-------> will use VI

-------> will use Linux basic commands (Tar,grep,find, etc.)

2. Recommended:

Tool Class Recommendation:

Code reading, editing tools: Kscope (Linux)

Telnet tool: C-kermit (Linux)

Recommend a book:

"Embedded Linux application Development"--Vedon
