+\section{Going further}
+
+At this point our board still uses the bootloaders
+(\code{at91bootstrap} and \code{U-Boot}) stored in the NAND flash.
+Let's try to have everything on our MMC card.
+
+The ROM code can load the first stage bootloader from an SD card, from
+a file named \code{BOOT.BIN} located in the first FAT partition of an
+MMC card.
+
+For this you will need to recompile \code{at91bootstrap} to support
+booting from an MMC card. When testing, do not forget to remove the
+NAND CS jumper!
