This guide was written on the assumption that you work on ODROID-C1 board. ODROID-C1 kernel can be built on HOST-PC using cross-compiler. But, libcec must be built and installed on ODROID-C1 board.

===== Kernel re-installation =====
**Get the ODROID-C1 kernel source code**
<code>
$ sudo apt-get update
$ sudo apt-get install lzop
$ git clone --depth 1 https://github.com/hardkernel/linux.git -b odroidc-3.10.y
$ cd linux
$ make odroidc_defconfig
</code>
**Select new CEC driver configuration**
  * Device Drivers ->
    * Amlogic Device Drivers ->
      * HDMI TX Supports ->
        * HDMI new CEC driver

**Install new kernel image**
<code>
$ make uImage -j4
$ sudo cp -f arch/arm/boot/uImage /media/boot/

<code>
$ sudo apt-get update
$ sudo apt-get install cmake liblockdev1-dev libudev-dev libxrandr-dev python-dev swig
$ git clone https://github.com/Pulse-Eight/platform.git
$ mkdir platform/build
$ cd platform/build
$ cmake ..
$ make
$ sudo make install
</code>
**Build & Install libcec for ODROID-C1**

$ cmake -DHAVE_AMLOGIC_API=1 ..
$ make -j4
$ sudo make install
