Install Headers 3.4.133

Hi!

First thanks to everyone!

I own a Banana PI M2 Zero

I realice most of the best images use the kernel 3.4.133 from this web https://github.com/BPI-SINOVOIP/BPI-M2Z-bsp

But anyone come with the headers installed .

Dkms needs them for a lot of drivers.

I tried to copy in to the /usr/scr folder but of couerse dosent work.

Can anyone explain me the procedure to install the headers for this kernel

Kind regards
