compiling kernel on orange PI OK

snowbody

You cannot compile the kernel on the OPI. (you have to crosscompile it)
However on the website of Jean Francois Moine ->  http://moinejf.free.fr/opi2/kernel-3.4.patch

I used the kernel of the Armbian project 3.4.110

(1)     I just replaced the Makefile in
/usr/src/h3-wip/arch/arm/mach-sunxi/power/brom
with the one displayed on the bottom

(2) and put the mksunxichecksum.c in that directory (compiled it with gcc .... -o mksunxichecksum)

(3) that's all -- you now can compile the kernel with make on the OPI (I used make -j3 this way you can make use of three cores)

Fine,
but how long it takes?

A full kernel compilation took about 2 hours in the background (I only used three cores for the compilation)

I'm playing with some modules, and then I only need the compilation of the changes, which is way faster (couple of minutes)
