I am working on omap paltform. When we press power on reset button ROM code will search for boo-table partition i.e FAT32.

My question is why first partition should be FAT32 . Can't we make first partition as ext2 or ext3?

When an OMAP processor is reset is first runs a boot ROM masked into the chip. One of the places this boot ROM can look for code is in a file named MLO in the first partition of an SD card. But the boot ROM only understands FAT32.

Other processors based on Cortex-A cores have similar but different boot rules.
