Configure kernel sources. Configuration will be permanent. There are many ways to edit source code, this method is focused for igep0020 RC without igep0022 support. <br> Go to [http://git.igep.es/?p=pub/scm/linux-omap-2.6.git;a=blob_plain;f=arch/arm/mach-omap2/board-igep0020.c;hb=db3cb47adf10504d3847d54927de50b2fa94c008 $(kernel path)/arch/arm/mach-omap2/board-igep0020.c] and search next line: <br>
