+ODROID-C2
+
+Intro
+=====
+To be able to use ODROID-C2 board with the images generated by
+Buildroot, you have to prepare the SDCard or eMMC.
+
+How to build it
+===============
+
+  $ make odroidc2_defconfig
+
+Then you can edit the build options using
+
+  $ make menuconfig
+
+Compile all and build rootfs image:
+
+  $ make
+
+Note: you will need to have access to the network, since Buildroot will
+download the packages' sources.
+
+Result of the build
+-------------------
+
+After building, you should obtain this tree:
+
+    output/images/
+    +-- bl1.bin.hardkernel
+    +-- bl2.package
+    +-- bl301.bin
+    +-- bl30.bin
+    +-- bl31.bin
+    +-- boot_new.bin
+    +-- boot.scr                   [1]
+    +-- boot.vfat
+    +-- fip.bin
+    +-- Image                      [2]
+    +-- meson-gxbb-odroidc2.dtb
+    +-- rootfs.ext2
+    +-- rootfs.ext4
+    +-- rootfs.tar
+    +-- sdcard.img
+    +-- u-boot.bin
+    +-- u-boot.img
+    +-- uboot-odc2.img             [3]
+
+[1] This is the ODROID-C2 configuration file used in u-boot.
+[2] This is the ODROID-C2 kernel image file which will be booted.
+[3] This is the ODROID-C2 signed u-boot image which will be used.
+
+How to write the SD card or eMMC
+================================
+
+Once the build process is finished you will have an image called "sdcard.img"
+in the output/images/ directory.
+
+Copy the bootable "sdcard.img" onto an SD card or eMMC with "dd":
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
+
+Insert the SDcard into your ODROID-C2, and power it up. Your new system
+should come up now.
