The construction of embedded Linux development environment and some ideas of embedded introduction __linux

Recently began to learn embedded Linux development, for embedded I was completely novice, but I still want to write something, to the later people to make a reference, so that some people less take detours.

1. Install the basic development environment under the host Linux:

$ sudo apt-get install build-essential
$ sudo apt-get Install Bison flex
$ sudo apt-get install Manpages-dev

2. Install the cross-compilation tool chain

As a novice, I recommend using a tool chain that has already been made (because I have tried to compile it myself, among them encountered countless wonderful problems, delayed a lot of time, but for themselves is also a exercise, if there is time I will tidy up the problems of compiling and then write a blog post.

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 function 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 tool chain is configured successfully

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

1. The knowledge and skills needed to get started:

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

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

-------> Understand makefile (Rules, common functions, etc.)

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

-------> will use VI

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

2. Recommended:

Tools Recommended:

Code reading, editing tools: Kscope (Linux)

Telnet tool: C-kermit (Linux)

Recommend a book:
