The IGEP X-Loader must reside in the microSD card or in the OneNand.<br>
The OMAP Processor loads the XLoader directly from the mmc or the OneNand and copy the binary into the internal processor RAM (0x40200000) and jump to this place, the XLoader initialization code can be found using this link:<br> [http://git.igep.es/?p=pub/scm/igep-x-loader.git;a=blob;f=cpu/omap3/start.S;h=4cbf4379b8502ebfe0409b35e4aafba712234c34;hb=HEAD start.S]<br>
