Raspberry Pi not supported? about rtl8812au

[astsam]

I see no reason why it is not possible if you have:

• cross toolchains
• kernel sources

$make ARCH=arm KSRC=<path to kernel sources> CROSS_COMPILE=<cross compiler prefix>

Yes thank you that is what I ended up doing. This worked:

make ARCH="arm" CROSS_COMPILE=arm-linux-gnueabihf- KSRC=/usr/src/linux-headers-4.4.45+/

I have tried this as well as the suggestion from ledjohnyy in #10. In both cases I can see the module compiles and I can install it and see '8812au' in the lsmod output.

What I can't figure out is how to get the interface to show up in either ifconfig or iwconfig. My Raspberry Pi 3 does not show any additional interfaces after running modprobe or a reboot.
@osenbruggen Did you have to do anything extra to get your interface to show up in iw/ifconfig?

Will you attach output of the lsusb and ip link commands.

And for good measure:

Plug adapter into USB 3.0 and attach dmesg output.

The issue has no relations to the driver, something wrong with your USB subsystem.

Thanks, I'll take a look. The other rtl8812au drivers worked fine, which is why I commented here. :)

I am using raspi zero w, how can cross compile according "make ARCH="arm" CROSS_COMPILE=arm-linux-gnueabihf- KSRC=/usr/src/linux-headers-4.4.45+/"
