+===== Toolchain =====
+Click one of the site to download toolchain to build U-boot. Please note that this toolchain is for U-boot, there is another toolchain to build Linux kernel.
+  * [[http://releases.linaro.org/archive/14.04/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2014.04_linux.tar.xz|Download #1]]
+  * [[http://dn.odroid.com/toolchains/gcc-linaro-arm-none-eabi-4.8-2014.04_linux.tar.xz|Download #2]]
+Once the download is done, extract the tarball to **/opt/toolchains/**.
+<code>
+$ sudo mkdir -p /opt/toolchains
+$ sudo tar xJvf gcc-linaro-arm-none-eabi-4.8-2014.04_linux.tar.xz -C /opt/toolchains/
+</code>
+In order to add the toolchain path to PATH, paste below lines to **$HOME/.bashrc**.
+<code>
+export PATH=/opt/toolchains/gcc-linaro-arm-none-eabi-4.8-2014.04_linux/bin:$PATH
+</code>
+You can apply the change if you login again or import
+to apply this change, login again or evaluate **$HOME/.bashrc** with source command.
+<code>
+$ source ~/.bashrc
+</code>
+You can check if the toolchain installed above works properly while checking the version of toolchain. If you can find **gcc version 4.8.3 20140401 (prerelease)** at the end of the line, the toolchain is well installed.

+===== Checkout & compile =====
+You can checkout **U-boot** source tree from **[[https://github.com/hardkernel/u-boot/tree/odroidc-v2011.03|Hardkernel's Github]]**.
+<code>
+$ git clone https://github.com/hardkernel/u-boot.git -b odroidc-v2011.03
+</code>
+Before you compile **U-boot**, you must configure for **ODROID-C1** with following command.
+<code>
+$ cd u-boot
+$ make odroidc_config
+</code>
+And finally you can compile **U-boot**.
+<code>
+$ make
+</code>
+===== Installation =====
+The bootloader for **ODROID-C1** is consisted with two part, **1st stage bootloader** + **U-boot**. You can find **u-boot.bin** once you compile **U-boot**, as well as **bl1.bin.hardkernel** in the directory **sd_fuse/**. Both binaries must be installed in a card (eMMC or MicroSD).
+<WRAP left round tip 70%>
+  * The 1st stage bootloader, **bl1.bin.hardkernel**, is provided as prebuilt binary only.
+  * Bootloader signing process is not necessary for **ODROID-C1** at all.
+</WRAP>
+==== Installation to blank card ====
+We provide the script, **sd_fuse/sd_fusing.sh**, this helps you to install the bootloader into your blank card eMMC or MicroSD.
+  - Insert your card to USB card reader and attach to USB host port of your desktop.
+  - Check the device path of your USB card reader.
+  - Install the bootloader binaries using **sd_fuse/sd_fusing.sh**.
+<code>
+$ cd sd_fuse
+$ ./sd_fusing.sh <device/path/of/your/card>
+</code>
+==== Installation using fastboot ====
+If you can boot your **ODROID-C1** already and want to install a new **u-boot.bin** built by you. Fastboot helps you to install a **u-boot.bin** into your board.
+<code>
+$ sudo fastboot flash bootloader sd_fuse/u-boot.bin
+</code>
+If installation is done, you care reboot your **ODROID-C1** with fastboot.
+<code>
+$ fastboot reboot
+</code>
+==== Updating from Linux ====
+You also can update U-boot from Linux with **dd** command. After building U-boot, copy **u-boot.bin** into your **ODROID-C1**. Then do the command below in order to flash your U-boot image to MicroSD or eMMC.
+<code>
+$ sudo dd if=u-boot.bin of=/dev/mmcblk0 bs=512 seek=64
+$ sudo sync
+</code>
