how to add wifi driver to kuiper Linux

Hi,

First of all, I recommend to use latest Kuiper image - 2021_R2. Kuiper images do not contain kernel headers, but they can be added.

After you boot Kuiper image, go in /usr/local/src, clone ADI linux repo, cd into it, checkout 2021_R2 branch and run "make adi_zynqmp_defconfig" then "make headers headers_install".

Thanks,

Stefan

Hi Stefan,

Thanks for your answer.

I cloned ADI linux repo to Kuiper linux, setted 2021_R2 branch. For defconfig I used xilinx_zynq_defconfig, because there is no adi_zynqmp_defconfig and after making headers install I see iaking and instalation process, but at the end then I try to install rtl 8812AU driver I get error. 

analog@analog:~/Desktop/awus036ach/8812au-20210629 $ uname -r
5.10.0-98748-g8c24c9b87bea

analog@analog:~/Desktop/awus036ach/8812au-20210629 $ sudo ./install-driver.sh

Your kernel header files aren't properly installed.
Please consult your distro documentation or user support forums.
Once the header files are properly installed, please run "sudo ./install-driver.sh"
analog@analog:~/Desktop/awus036ach/8812au-20210629 $

Same driver works perfectly on VM running Ubuntu

The adi_zynqmp_defconfig file exists in repo: https://github.com/analogdevicesinc/linux/blob/master/arch/arm64/configs/adi_zynqmp_defconfig.

Also make sure that the location of repo is /usr/local/src/linux and that inside  /lib/modules/<uname -r>  there are two shortcuts "build" and "source" that point to that folder. You can create them with:

rm -rf ./build ./source

ln -s /usr/local/src/linux ./build

ln -s /usr/local/src/linux ./source

hi,

After successful  headers installation I get additional errors when trying to install wifi drivers. The problem as I understand is with Modules. 

make ARCH=arm CROSS_COMPILE= -C /lib/modules/5.10.0-98725-g3eae70065be9-dirty/build M=/home/analog/Desktop/rtl8812au modules
make[1]: Entering directory '/usr/local/src/linux'

make: *** [Makefile:1724: modules] Error 2

When building new kernel I saw that if I choose at menuconfig the driver using <M> it doesn't load. Only chooses with <*> at make menucofig does the trick and you can use the driver. Maybe that's the problem. I'll try to add driver for 8812AU directly to kernel.

Best regards,

Mindaugas

Shortcuts from /lib/modules/<uname -r> seems ok, but there is missing "Module.symvers" file.

This means that the problem is with the modules. Most probably you'll need to build modules locally:

cd /usr/local/src/linux 

make modules 

If still doesn't work, you can also try "make modules_install" afterwards.

Thanks,

Stefan

Hi,

I build modules and installed them.

Compilation of the driver starts and compiles most of the files, but at the end  same Module.symvers error appears.
