Hi,
I' trying to enable SPI on the Overo, following the instructions on this thread: http://old.nabble.com/Gumstix-Overo-SPI-read-problems-td29770472.html#a29770472.
The problem is that when i directly modify the files, linux-omap3-2.6.34 is not rebuild since it is already build. When I issue bitbake --cmd=clean linux-omap3-2.6.34 the changes I've made in board-overo.c are lost.
I think this would be solved applying a patch, but how should I do that?
Where should be the patch file and how would be the sintax in the bb file?

Thanks,
Mathias
