How to include the Realtek RTL8812au driver in Android 5.0 x86 ?

[Pque Christopher]

Hello,

I have the Asus AC56r, a next gen USB dongle WIFI and I would like to know how to include its driver in the Android x86 ROM. The RTL8812au driver is working perfectly in Lubuntu 15.04 so I think it is possible to make this driver on Android 5.0 x86.

So, now,  my question is, how to install (steps, pictures, explainations, etc) the driver for the 8812au on Android x86 5.0 as I don't have no internet on Android ?

Thx

Hi Christopher!

Can you check your lubuntu installation which kernel module,... is loaded for your WiFi Card

I think you have to build an extra kernel module for RTL8812AU (e.g. https://github.com/gnab/rtl8812au)

I'm also playing around with integrating RTL8723BS WiFi for my TrekStor 7.0 Tablet so you have the same goal than me.

I only got it working under Ubuntu so far but next step would be to integrate it also in 4.x kernel for Android-x86

regards

Hello, I didn't understand about the check kernel module ? one thing is sure is that i have installed the driver from the same site : https://github.com/gnab/rtl8812au

i downloaded  it and then on  Lubuntu I installed the driver  and it worked (with a lot less features than the Windows counterpart but it worked  good)

I saw some tutorials on internet for loading a driver on Android  x86 but it is for old versions  of android   4.0 and the driver  is  too different.

[Mario Holzinger]

on unix based operation system we are talking about kernel modules (driver is more MS-Windows like) that were loaded automatically when the device is connected.

A kernel modul is always compiled against a specific kernel version (like Windows 8 drivers that will not work on Windows 10)

so in normal cases what you will need to compile the kernel module are

- the sources of the kernel module https://github.com/gnab/rtl8812au

- kernel header files of the kernel you are trying to compile the kernel for

with this 2 you are able to compile the module

after completion you will get a .ko file that needs to be placed in systems partition /lib/modules/KERNEL_VERSION/..

of your target device with the RTL8812au WiFi module

regards Mario

BTW: If you like to compile the module directly with the whole kernel and/or with the complete android-x86 sources you can adapt the following commit to match your staging kernel module

https://github.com/meijjaa/linux/commit/4919ef61dbabc7dc8cfd3b83983c6e94425d2cd3

Sorry, I am on Windows and I really don't know how to start the compilation, for the sake of helping me and others that  will come to read this post, with what software do I start with knowing that :

- I have the ISO of Android x86 5.1
- I am on Windows

[Povilas Staniulis]

For starters, to build a Linux driver, you need Linux. Either a double-boot configuration (with Windows) or in a virtual machine (eg. VirtualBox).
Ubuntu or Debian should do, but you can pick any distro, provided it has the right tools.

Hello,

I have Lubuntu 15.04 and the Asus AC56 (RTL 8812Au) is working good on it at least to connect to Wifi networks. So my question is, how to compile the Android Kernel 6.0 to include the AC56 module ?

There is no explicit tutorial with explicit steps (1, 2, 3, etc...) only outdated ones for the moment.

Thank you everyone, very much, I love you all :)
