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.
