HII , I AM USING A DE1-SOC BOARD THAT IS BASED ON U-Boot SPL 2013.01.01

THE BOARD IS :Altera SOCFPGA Cyclone V Board

i downloaded the console version of linux os from terasic and its working fine on the board

I am trying to load a simple lkm that prints "hello world" on the kernel , and in the makefile we need to specify the source directory location. I tried all the options and examples of makefiles that I could lay my hands on , and nothing seems to work .

in some cases it worked but when i try to load the module on the board using insmod command i get "invalid file format "

The module needs to be built for exactly the same kernel version. Any difference at all in the version number will cause it to fail.

i tried to get some help in roketboard forum and in intel community forums without any success , so i thought maybe i can get help from you cause from what i understand the console ver is based on U-Boot SPL 2013.01.01

i need to know the path where are the source files located in U-Boot SPL 2013.01.01

Perhaps this:

https://github.com/u-boot/u-boot/tree/u-boot-2013.01.y

That version of U-Boot probably belongs in a museum at this point! I won't ask what version Linux it is :-)

and if you have a make file that is tested on the de1-soc maybe for compiling linux kernel modules (device drivers) i be glad for any help ,thanks in advance
