= '''准备源码(prepare source code)''' =
----
== '''下载源码包(download source code package)''' ==
在网盘下载 rtl8188EUS_linux_v4.3.0.9_15178.20150907.tar.xz<br>
<span style="background:#CCCCCC">download rtl8188EUS_linux_v4.3.0.9_15178.20150907.tar.xz from the network disk</span><br>

== '''解压源码包(decompress source code package)''' ==
=== 创建工作目录(create working directory) ===
这里我们创建 ~/my-demo/exclude_src 目录，并在该目录下工作。<br>
<span style="background:#CCCCCC">here we create ~/my-demo/exclude_src directory，and work under the directory。</span><br>
<span style="background:yellow">$ mkdir ~/my-demo/exclude_src -p<br></span>

=== 复制源码包到工作目录（copy source code package to working directory） ===
将下载的源码包复制到 ~/my-demo/exclude_src 。<br>
<span style="background:#CCCCCC">copy source code package downloaded to ~/my-demo/exclude_src 。</span><br>
这一步自己采取相应方式完成。<br>
<span style="background:#CCCCCC">next step should be done in your own way</span><br>

=== 解压源码(decompress source code package) ===
*进入源码目录<br>
<span style="background:#CCCCCC">enter source code directory</span><br>
<span style="background:yellow">$ cd ~/my-demo/exclude_src<br></span>
*解压<br>
<span style="background:#CCCCCC">decompress</span><br>
<span style="background:yellow">$ tar xf rtl8188EUS_linux_v4.3.0.9_15178.20150907.tar.xz<br></span>

= '''编译模块(compile module)''' =
----
== '''检查配置(check configuration)''' ==
说明：模块编译存在两个依赖关系，交叉编译编译链和内核，并且需要在指定路径。<br>
<span style="background:#CCCCCC">instruction：module compilation exist with two dependent relationships，cross compilation link and kernel，which need to be in the path designated</span><br>
* 使编译配置文件生效
<span style="background:#CCCCCC">validate configured file of compilation</span><br>
<span style="background:yellow">$ source ~/my-sama5/03_tools/gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf.config<br></span>
[[文件:myimx6linux3.14_build_5.2.1.1.png]]<br>
*检查内核源码路径
<span style="background:#CCCCCC">check path of source code in kernel</span><br>
<span style="background:yellow">$ ls ~/my-sama5/02_source/linux-at91-linux4sam_4.7<br></span>
如果内核源码存在并且路径正确会看到内核源码目录的内容。<br>
<span style="background:#CCCCCC">if there is kernel source code and in correct path then content of kernel source code directory can be found</span><br>
如果命令的执行结果异常，需要按照《MY-SAMA5 L318 编译手册》重新编译一次内核。<br>
<span style="background:#CCCCCC">if result of execution of command is anormal，need to re-compife kernel with reference to《MY-SAMA5 L318 compilation manual》</span><br>

== '''编译(compile)''' ==
*进入驱动代码目录
<span style="background:#CCCCCC">enter driving code directory</span><br>
<span style="background:yellow">$ cd rtl8188EUS_linux_v4.3.0.9_15178.20150907/<br></span>
*执行编译命令
<span style="background:#CCCCCC">execute compilation command</span><br>
<span style="background:yellow">$ make<br></span>

== '''目标文件(target file)''' ==
*查看目标文件信息
<span style="background:#CCCCCC">check target file information</span><br>
<span style="background:yellow">$ file *.ko<br></span>
执行 file 命令可以看到编译出来的模块的信息，类似如下：<br>
<span style="background:#CCCCCC">execute file command to see module information compiled，example</span><br>
8188eu.ko: ELF 32-bit LSB relocatable, ARM, version 1 (SYSV), BuildID[sha1]=0x1a3bbb865d785effc8acfebf9e2c8faf066b3fbf, not stripped<br>
'''8188eu.ko 即编译得到的目标文件'''<br>
<span style="background:#CCCCCC">8188eu.ko is the target file compiled</span><br>
