The first part is the kernel
Rk kernel configuration reference documents related to the wireless check on the next device driver.
Buildin compiled into a problem, not recognize, so I plan to be compiled into ko
cd kernel/drivers/net/wireless/rockchip_wlan/rtl8188eu
make -C /home/lzm/workspace/rk3288/zy_n10/kernel/ M=`pwd` modules
Get 8188eu.ko
lsusb, see the vid pid, is there
Look initialization function, found to be annotated, modified open
A second portion, android open configuration Settings

build in android source directory / envsetup.sh document that describes compile command
- 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.
To use these commands, you first need to perform. Build / envsetup.sh script sets up the environment in the android source code root directory
m: compiling all modules
mm: compilation module in the current directory, the files in the current directory have Android.mk
mmm: the module must be compiled at the specified path, the file path specified Android.mk
Here's an example, assume \ hardware \ libhardware_legacy \ power module to compile my android under the current directory to the root directory of the source, as follows:
1、. build/envsetup.sh
2、mmm hardware/libhardware_legacy/power/
or:
1、. build/envsetup.sh
2、cd hardware/libhardware_legacy/power/
