== Image setup ==
=== How to setup an image ===
* Extract the image
 # unxz <image name>.img.xz
* Transfer the image
 # dd bs=4k conv=fsync if=<image name>.img of=/dev/sdb

== OS Setup ==

==== DVI Support ====

=== How to enable HDMI Support ===
The default imagest doesn't support HDMI-DVI converters<br>
'''REFERENCE:''' http://boundarydevices.com/dvi-support-on-i-mx6-boards

* In order so setup a fixed resolution, add to <tt>>uEnv.txt</tt>
 video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32
Otherwise the best higher resolution will be choosen.

=== Hpw to enable OpenGL suport ===
Kind of message like this
  libEGL warning: DRI2: failed to authenticate
  [ error ] ofAppGLFWWindow: 65544: X11: RandR gamma ramp support seems broken
  X Error of failed request:  BadMatch (invalid parameter attributes)
    Major opcode of failed request:  72 (X_PutImage)
    Serial number of failed request:  120
    Current serial number in output stream:  121
Can be solved updating all the mesa packages to the same version
 # apt-get install libopenvg1-mesa libgl1-mesa-dri libgl1-mesa-dev libgbm1

=== How to build Mesa video drivers on a new kernel ===
'''Reference:''' http://www.solid-run.com/community/viewtopic.php?f=8&t=851

* Get the latest open source driver
 # git clone https://github.com/laanwj/etna_viv

* Build the driver
  # cd etna_viv
  # export GCABI=imx6_v4_1_0
  # make

* Get the mesa fork for the library generated above: <tt>libetnaviv.a</tt>
  # git clone https://github.com/laanwj/mesa

* Install dependencies to build the mesa driver
 # apt-get -y install x11proto-dri3-dev x11proto-present-dev

* Configure the mesa driver
:* First pass to try to trick the intel drivers
  # cd mesa
  #./autogen.sh --with-driver=dri INTEL_CFLAGS=disable INTEL_LIBS=disable

:* Second pass to enable etnaviv

 # cd libdrm-armada
 # autoreconf --install
 # ./configure --prefix=/usr
 # make & sudo make install

* Get the sources
