Hi: Thanks for your answer! So I must flash the u-boot.Rom in the spi flash, and boot from them, but I still can put the rest of the system in the ad and configure u-boot to load kernel and device-tree from sd, am I right?
Correct. x86 U-Boot can load kernel from an SD card. This is a common U-Boot feature.
What flashing tool would you recommend me?
Dediprog SF100.
Thanks again Pablo

Hi:
I previously worked with u-boot for beaglebone black for booting a custom linux system. Now the university got a donnation of some galileo boards, and we want to do something similar.
The problem is that we don't know what we need to put into the sd card to make the board boot from it... With beaglebone i had to copy the u-boot.img and MLO, but is not the same with galileo an we don't know where to find that information.
You need a SPI flash programmer to burn u-boot.rom into the SPI flash. Unlike most ARM boards, U-Boot boots directly from reset vector on IA, thus there is no way to put u-boot.rom on an SD card and let the processor boot from there.
We used galileo_defconfig and instructions in README_x86 for building u-boot, but now we do not know how to proceed. Anyone could give me some hints?
