		+
		+	1 - Generate an x-loader with serial support
		+	mkdir serial_boot
		+	cd serial_boot
		+	git clone http://git.omapzoom.org/repo/u-boot.git
		+	git clone http://git.omapzoom.org/repo/x-loader.git
		+	cd x-loader
		+	make distclean
		+	make omap3430labradordownload_config
		+	make
		+	cd ..
		+
		+	now you've got an ~13k x-load.bin in the x-loader directory.
		+
		+	2 - Generate Nishant Menon's tools
		+	git clone git clone http://github.com/nmenon/omap-u-boot-utils.git
		+	cd omap-u-boot-utils
		+	make distclean
		+	make
		+
		+	now you've got two tools: pserial and ukermit
		+
		+	3 - Pick up the U-Boot you'd like to put in SDRAM
		+
		+	You can either use the one generated by OE, or you can quickly generate a new one:
		+	cd ..
		+	git clone http://git.denx.de/u-boot.git u-boot-denx
		+	cd u-boot-denx
		+	make distclean
		+	make omap3_beagle_config
		+	make
		+	cd ..
		+
		+	now you've got an ~160k u-boot.bin in the u-boot-denx directory.
		+
		+	4 - Prepare the boot
		+	cd omap-u-boot-utils
		+	cp ../x-loader/x-load.bin .
		+	cp ../u-boot-denx/u-boot.bin .
		+
		+	5 - Boot (use the right tty for your setup of course)
		+
		+	Power off the board.
		+
		+	Run pserial to put the x-loader in the internal SRAM:
		+	./pserial -p /dev/ttyS0 -f x-load.bin
		+
		+	If you already have an x-loader in NAND, you must push the User Button
		+	so that the NAND boot is tried after the UART boot, then power-on the
		+	board.
		+
		+	If you don't have one, simply power-on the board.
		+
		+	You see:
		+	Waiting For Device ASIC ID: Press Ctrl+C to stop

		+	Sending 2ndFile:
		+	Downloading file: 100.000% completed(12700/12700 bytes)
		+	File download completed.
		+
		+	Then run ukermit, to transmit the u-boot to the x-loader and then the
		+	x-loader puts it in SDRAM:
		+	./ukermit -p /dev/ttyS0 -f u-boot.bin
		+
		+	You see:
		+	Downloading file: 100.000% completed(162656/162656 bytes)
		+	File Download completed
		+
