OMAP35xx , DM37xx, AM335x or DM37xx OMAP5 processors can boot from a microSD. IGEPv2 or All IGEP COM MODULE boards use the microSD card as highest boot priority, it means that the processor try to boot from the microsd card before try to boot from other devices such the OneNand, Nand, SSD or eMMC.
There exist some rules to boot from a microSD card.
*The microsd card must be content at latest 2 partitions.
*The first one must be primary partition with the boot flag mark and formated using FAT (16 or 32) file system. *All names used in this partition must be msdos names, it means (if you cannot use a extended namesold OMAP3 processor). *The processor must load a first program called '''MLO''', this program must reside in the first partition, this program it's also called '''x-loaderor uboot-spl.'''
''The processor ONLY load and execute the MLO program and ignore all the rest it's the X-loader(MLO) the program responsible to load the next programs such kernel or uboot if you use this last one approach.''
Therefore, we are going to '''setup a microSD card with these requirements''' and '''install a custom software distribution''' into it.
