Hi,
I'm trying to install driver for my wifi dongle that is equipped with rtl8812bu chip.

 

I have been searching over the net for a few days, but have been unable to successfully install the driver.

What I tried:
I'm using latest availabel Armbian_5.75_Rock64_Debian_stretch_default_4.4.174_desktop.img
After first boot, I did apt-get update and upgrade.

Then in armbian-config, I installed "Headers, Source and Full firmware package".
then extracted 
linux-source-4.4.174-rockchip64.tar.xz and 
linux-rockchip64-default_4.4.174_5.75_config.xz 
in /usr/src/linux-headers-4.4.174-rockchip64 directory.

After that applied the workaround found here.
"make scripts" works after without any error after above steps.

now the driver.
The dongle comes with a cd with the linux driver in it.
The drivers compiles fine,  but at the last step I get 

modprobe: ERROR: could not insert '88x2bu': Exec format error

I can provide full output if required.

Next. I tried this driver:
https://github.com/cilynx/rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959

I found this comment on this forum that says he was able to install the driver in rockpro64
although I followed basically same procedure (except building armbian myself),
The installation was not successfull.
I got 

modprobe: ERROR: could not insert '88x2bu': Exec format error

when I executed the last command 
"modprobe 88x2bu"

This is what I found in dmesg 
 

[31040.865892] 88x2bu: version magic '4.4.173-rockchip64 SMP mod_unload aarch64' should be '4.4.174-rockchip64 SMP mod_unload aarch64'

all previous command succeeded without any error.

So can anyone please help?
Let me know if I should provide any other log or anything.

Thanks in advance.

Update: Did
 

modprobe --force 88x2b

now if I insert the device, I get :

Armbian provides kernel headers while 3rd party wireless chip drivers are user's problem. Try to work this out with a driver maintainer - if any.

Armbian is maintained by a few, not by a hundred people. 

Moved to general section since support is related for onboard hardware only.
