+3.	Compilation
+
+	Assuming you're using BASH (or similar) as your shell:
+
+	export CROSS_COMPILE=your-cross-compiler-prefix-
+	make distclean
+	make SIMPC8313_LP_config
+	(or make SIMPC8313_SP_config, depending on the page size
+	of your NAND flash)
+	make
+
+4.	Downloading and Flashing Images
+
+4.1	Reflash U-boot Image using U-boot
+
+	=>run update_uboot
+
+	You may want to try
+	=>tftp $loadaddr $uboot
+	first, to make sure that the TFTP load will succeed before it
+	goes ahead and wipes out your current firmware.  And of course,
+	if the new u-boot doesn't boot, you can plug the board into
+	your PCI slot and with the supplied driver and sample app
+	you can reburn a working u-boot.
+
+4.2	Downloading and Booting Linux Kernel
+
+	Ensure that all networking-related environment variables are set
+	properly (including ipaddr, serverip, gatewayip (if needed),
+	netmask, ethaddr, eth1addr, fdtfile, and bootfile).
+
+	=>tftp $loadaddr uImage
+	=>nand write $loadaddr kernel $filesize
+	=>tftp $loadaddr $fdtfile
+	=>nand write $loadaddr 7e0000 1800
+
+	=>boot
+
+5	Notes
+
+	The console baudrate for SIMPC8313 is 115200bps.
