'''(work in progress)'''

 

== Overview ==

* OpenGL|ES acceleration

* DSP-accelerated media playback with GStreamer (work in progress)

 

GeeXboX is currently being developed under the [http://www.openbricks.org OpenBricks] project, an enterprise-grade embedded Linux framework that provides easy creation of custom distributions for industrial embedded devices.

This How-To is meant to be a starting point for people to learn install a GeeXboX image for IGEP v2 devices as quickly and easily as possible.

* The GeeXboX website ( http://www.geexbox.org )

* The OpenBricks website (http://www.openbricks.org )

* The Enna website ( http://enna.geexbox.org )

It is possible trunk can suffer temporary periods of instability while new features are developed and if this is undesirable we recommend using one of the release branches. '''Use ONLY for development purposes.'''</span>

GeeXbox uses GeeXboX and OpenBricks use Mercurial as a revision control system, so you will install the mercurial package for your host systesystem. On an Ubuntu-based system this will be done with,

$ sudo apt-get install mercurial

Now, the first thing you will do is download the sources from Mercurial OpenBricks repository (which is where bleeding-edge GeeXboX repositorydevelopment is done).

$ hg clone http://hg.geexboxopenbricks.org/geexboxopenbricks

Next, enter configure OpenBrics to geexbox directory and edit with your preferred editor build a GeeXboX image for the config/options fileOMAP3 platform. SetRun

TARGET_ARCH=arm TARGET_CPU=cortex-a8 SERVICES=yes XORG_DRIVERS="omapfb" PULSEAUDIO=no GSTREAMER=yes DEVTOOLS=yes$ make menuconfig

Finally build the distribution withand set

$ make flatFlavour -> GeeXboX

General Setup -> Target architecture (arm) -> Target sub-architecture (ARMv7 / Cortex) -> Target platform (OMAP3) -> Target CPU (cortex-a8) -> FPU optimizations (NEON) Settings -> Target Images -> Flat root Features -> Audio -> deselect PulseAudio (recommended, for now PulseAudio has been tested only on x86) If you want to enable OpenGL|ES acceleration set  Features -> Enable non-free components Features -> Hardware Accelerators -> EGL -> OpenGL -> OpenGL|ES -> OpenVG -> EGL provider (SGX) -> OpenGL|ES provider (SGX) -> OpenVG provider (SGX) If you want to enable OpenMAX acceleration set  Features -> Enable non-free components Features -> Hardware Accelerators -> OpenMAX -> OpenMAX provider (TI OpenMAX IL) If you want to enable TI DSP acceleration (lightweigth alternative to OpenMAX for DSP acceleration)  Features -> Enable non-free components Features -> Hardware Accelerators -> TI C64x DSP Optionally select other features or packages you may need. Exit and save the configuration, then build with  $ make The result resulting rootfs will ...be placed in the binaries directory directory

== Make a bootable MMC card with GeeXbox ==

Prepare your MicroSD First prepare the SD card the following way (and order):* create one boot FAT32 (type 0B) partition, any size, I took 8MB* create one rootfs EXT2 partition. Then copy the uImage and boot.ini files to FAT32 partition (paths relative to the rootfs location)

* Copy / $ cp boot/* (uImage and boot.ini script) to FAT32 partition/media/boot* Copy all other files $ cp boot/dirs to EXT2 partition.uImage /media/boot

IGEP v2 detects Finally, copy the boot.ini script which contains all the necessaryinstructions for rootfs contents to EXT2 partition (paths relative to the OS to auto-boot.rootfs location)

== Annex: Known issues and solutions == $ fakeroot cp -dpfa -R * /media/rootfs/

=== Requested 'dbusWith default environment the IGEP v2 detects the boot.ini script which contains all the necessary instructions for the OS to auto-1 >= 1.2.16' but version of dbus is 1.1boot.20 ===

The libnih package fails, libnih is compiled for host == Annex: Known issues and for target so your host system needs at least version 1.2.16 of dbus-1.solutions ==
