rk3288 usb无线网卡支持 8188eu

第一部分是kernel

内核配置参考rk文档,把device driver 下wireless相关的先勾选上。

编译到buildin有问题,识别不到,所以打算编译成ko

cd  kernel/drivers/net/wireless/rockchip_wlan/rtl8188eu

make -C /home/lzm/workspace/rk3288/zy_n10/kernel/  M=`pwd` modules

得到8188eu.ko

lsusb,看vid pid,是存在的

看初始化函数,发现被注释,修改打开

第二部分,android打开Settings配置

rk这个有点坑了。。。

编译完放置在 /system/lib/

单独编译:

You're building on Linux

Lunch menu... pick a combo:
     1. rk3288-user
     2. rk3288-userdebug
     3. rk3288_box-userdebug
     4. rk3288-eng

Which would you like? [aosp_arm-eng] 2

cd hardware/libhardware_legacy

mm

android源码目录下的build/envsetup.sh文件,描述编译的命令

  • m: Makes from the top of the tree.
  • mm: Builds all of the modules in the current directory.
  • mmm: Builds all of the modules in the supplied directories.

要想使用这些命令,首先需要在android源码根目录执行. build/envsetup.sh 脚本设置环境

m:编译所有的模块
mm:编译当前目录下的模块,当前目录下要有Android.mk文件
mmm:编译指定路径下的模块,指定路径下要有Android.mk文件

下面举个例子说明,假设我要编译android下的\hardware\libhardware_legacy\power模块,当前目录为源码根目录,方法如下:

1、. build/envsetup.sh
2、mmm hardware/libhardware_legacy/power/

或者 :

1、. build/envsetup.sh
2、cd hardware/libhardware_legacy/power/
3、mm

adb shell am start com.android.settings/com.android.settings.Settings
