MY-IMX6 Linux-3.14.52 RTL8188EU 开发指导

下载源码包(download source code package)

在网盘下载 rtl8188EUS_linux_v4.3.0.9_15178.20150907.tar.xz
on network disk download rtl8188EUS_linux_v4.3.0.9_15178.20150907.tar.xz

解压源码包(decompress source code package)

创建工作目录(create work directory)

这里我们创建 ~/my-demo/exclude_src 目录，并在该目录下工作。
here we create ~/my-demo/exclude_src directory，and work under the directory。
$ mkdir ~/my-demo/exclude_src -p

复制源码包到工作目录(copy source code package to work directory)

将下载的源码包复制到 ~/my-demo/exclude_src 。
copy source code package downloaded to ~/my-demo/exclude_src 。
这一步自己采取相应方式完成。
this step is done by your own approach。

解压源码(decompress source code package)

• 进入源码目录
  

enter source code directory

$ cd ~/my-demo/exclude_src

• 解压
  

decompress
$ tar xf rtl8188EUS_linux_v4.3.0.9_15178.20150907.tar.xz

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。
instruction：module compilation exist with two dependent relationships，cross compilation link and kernel，which need to be in the path designated。

• 使编译配置文件生效

make effective configured file of compilation)
$ source ~/my-imx6/03_tools/gcc-linaro-arm-linux-gnueabihf-492-env

• 检查内核源码路径

check path of source code in kernel
$ ls ${HOME}/my-imx6/02_source/linux-3.14.52
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。
if there is kernel source code and in correct path then content of kernel source code directory can be found。
如果命令的执行结果异常，需要按照《MY-IMX6 L31452 编译手册》重新编译一次内核。
if result of execution of command is anormal，need to re-compife kernel with reference to《MY-IMX6 L31452 compilation manual》.

编译(compilation)

• 进入驱动代码目录

enter driving code directory
$ cd rtl8188EUS_linux_v4.3.0.9_15178.20150907/

• 执行编译命令

execute compilation command
$ make

目标文件(target file)

(== ' ==)

• 查看目标文件信息

check target file information
$ file *.ko
执行 file 命令可以看到编译出来的模块的信息，类似如下：
execute file command to see module information compiled，example：

8188eu.ko: ELF 32-bit LSB relocatable, ARM, version 1 (SYSV), BuildID[sha1]=0x1a3bbb865d785effc8acfebf9e2c8faf066b3fbf, not stripped

8188eu.ko 即编译得到的目标文件(8188eu.ko is the target file compiled)
8188eu.ko is the target file compiled
