+Samsung XE303C12 aka Chromebook Snow
+====================================
+
+This file describes booting the Chromebook from an SD card containing
+Buildroot kernel and rootfs, using the original bootloader. This is
+the least invasive way to get Buildroot onto the devices and a good
+starting point.
+
+The bootloader will only boot a kernel from a GPT partition marked
+bootable with cgpt tool from vboot-utils package.
+The kernel image must be signed using futility from the same package.
+The signing part is done by sign.sh script in this directory.
+
+It does not really matter where rootfs is as long as the kernel is able
+to find it, but this particular configuration assumes the kernel is on
+partition 1 and rootfs is on partition 2 of the SD card.
+Make sure to check kernel.args if you change this.
+
+Making the boot media
+---------------------
+Start by configuring and building the images.
+
+	make chromebook_snow_defconfig
+	make menuconfig # if necessary
+	make
+
+The important files are:
+
+	uImage.kpart (kernel and device tree, signed)
+	rootfs.tar
+	bootsd.img (SD card image containing both kernel and rootfs)
+
+Write the image directly to some SD card.
+WARNING: make sure there is nothing important on that card,
+and double-check the device name!
+
+	SD=/dev/mmcblk1		# may be /dev/sdX on some hosts
+	dd if=output/images/bootsd.img of=$SD
+
+Switching to developer mode and booting from SD
+-----------------------------------------------
+Power Chromebook down, then power it up while holding Esc+F3.
+BEWARE: switching to developer mode deletes all user data.
+Create backups if you need them.
+
+While in developer mode, Chromebook will boot into a white screen saying
+"OS verification is off".
+
+Press Ctrl-D at this screen to boot Chromium OS from eMMC.
+Press Ctrl-U at this screen to boot from SD (or USB)
+Press Power to power it off.
+Do NOT press Space unless you mean it.
+This will switch it back to normal mode.
+
+The is no way to get rid of the white screen without re-flashing the bootloader.
+
+Troubleshooting
+---------------
+Loud *BEEP* after pressing Ctrl-U means there's no valid partition to boot from.
+Which in turn means either bad GPT or improperly signed kernel.
+
+Return to the OS verification screen without any sounds means the code managed
+to reboot the board. May indicate properly signed but invalid image.
+
+Blank screen means the image is valid and properly signed but cannot boot
+for some reason, like missing or incorrect DT.
+
+In case the board becomes unresponsive:
+
+* Press Esc+F3+Power. The board should reboot instantly.
+  Remove SD card to prevent it from attempting a system recovery.
+
+* Hold Power button for around 10s. The board should shut down into
+  its soft-off mode. Press Power button again or open the lid to turn in on.
+
+* If that does not work, disconnect the charger and push a hidden
+  button on the underside with a pin of some sort. The board should shut
+  down completely. Opening the lid and pressing Power button will not work.
+  To turn it back on, connect the charger.
+
+Partitioning SD card manually
+-----------------------------
+Check mksd.sh for partitioning commands.
+
+Use parted and cgpt on a real device, and calculate the partition
+sizes properly. The kernel partition may be as small as 4MB, but
+you will probably want the rootfs to occupy the whole remaining space.
+
+cgpt may be used to check current layout:
+
+	output/host/usr/bin/cgpt show $SD
+
+All sizes and all offsets are in 512-byte blocks.
+
+Writing kernel and rootfs to a partitioned SD card
+--------------------------------------------------
+Write .kpart directly to the bootable partition:
+
+	dd if=output/images/uImage.kpart of=${SD}1
+
+Make a new filesystem on the rootfs partition, and unpack rootfs.tar there:
+
+	mkfs.ext4 ${SD}2
+	mount ${SD2} /mnt/<ROOTFS-PARTITION>
+	tar -xvf output/images/rootfs.tar -C /mnt/<ROOTFS-PARTITION>
+	umount /mnt/<ROOTFS-PARTITION>
+
+This will require root permissions even if you can write to $SD.
+
+Kernel command line
+-------------------
+The command line is taken from board/chromebook/snow/kernel.args and stored
+in the vboot header (which also holds the signature).
+
+The original bootloader prepends "cros_secure console= " to the supplied
+command line. The only way to suppress this is to enable CMDLINE_FORCE
+in the kernel config, disabling external command line completely.
+
+That's not necessary however. The mainline kernel ignores cros_secure,
+and supplying console=tty1 in kernel.args undoes the effect of console=
+
+Booting with console= suppresses all kernel output.
+As a side effect, it makes /dev/console unusable, which the init in use must
+be able to handle.
+
+WiFi card
+---------
+Run modprobe mwifiex_sdio to load the driver.
+The name of the device should be mlan0.
