Adding Broadcom wireless driver BCMDHD to kernel

[Javad Alipanah]

Hi everyone,

I am trying to build android-x86 marshmallow for Rugged Tablet PC (You can see the details of product I am using here).
The build was successful but I have some problems with wireless driver.
I realized that I need BCMDHD driver but I couldn't customize kernel to add this driver because I couldn't find this driver in menuconfig.
I know the wireless needs this driver to work because it has a default OS (Android-IA) which is running well and has the right driver for wireless; you can see the lsmod command outputs below the post.
I will be grateful if someone instruct me how to add this driver to kernel.

Thanks for your attention.

The bcmdhd is not a standard linux driver.
You should ask your vendor to get it.
Alternatively, try the standard linux broadcom driver
like brcmfmac. Read this to see if your chipset is supported:

Another way is to just use the prebuilt kernel and modules
shipped with your device.

Hello Chih-Wei

Can you give us some guide on how to build android-x86 with the prebuilt kernel from some device? This is something I was searching for for a long time?

How to extract the prebuilt kernel of your device
is beyond the topic of this forum.
