Add driver to linux kernel

Question

Hi,

I need to transfer video data into DDR and read it back. I want to add the VDMA driver from Xilinx-github

I've tried the instructions in the ReadMe file but unable to compile it.

How can I build the kernel using it ?

Also do I need PetaLinux for this purpose ?

Thanks in Advance

and modify file .settings64.sh

If using a 64bit OS then install 32bit packages

sudo apt-get install gawk

sudo apt-get install build-essential

sudo apt-get install automake

sudo apt-get install libtool

sudo apt-get install lib32ncurses5

sudo apt-get install lib32ncurses5-dev

sudo apt-get install lib32ncursesw5

sudo apt-get install ncurses-dev:i386

sudo apt-get install libstdc++6:i386

sudo apt-get install libselinux1:i386

now open a new terminal from the extracted files downloaded for kernel from github and type

export CROSS_COMPILE=arm-xilinx-linux-gnueabi-

source /Xilinx/SDK/2015.2/settings64.sh (path to SDK source file)

finally built kernel will be at /path/to/linux-digilent-master-main/arch/arm/boot

Hope this can be useful to others
