Overview

GeeXboX is a free embedded Linux distribution which aims at turning your computer into a so called HTPC (Home Theater PC) or Media Center. You can use it on a diskless computer, the whole system being loaded in RAM. Some points to note:

• Whole system being loaded in RAM.
• OpenGL|ES acceleration
• DSP-accelerated media playback with GStreamer (work in progress)

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.

Requirements

• A GNU/Linux-based host system.
• A SD card

How to build the development branch

Note: The development branch is where the development work takes place and you should use this if you're after to work with the latest cutting edge developments. 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.

GeeXbox uses Mercurial as a revision control system, so you will install the mercurial package for your host syste. 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 GeeXboX repository.

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

Next, configure geexbox for omap3 based architecture. Run

$ make menuconfig

and set

General Setup -> Target architecture (arm)
              -> Target sub-architecture (ARMv7 / Cortex)
              -> Target platform (OMAP3)
              -> Target CPU (cortex-a8)
    

Exit and save the configuration, then build with

$ make flat

The result will be in geexbox-flat-devel-*.arm.eglibc directory

Make a bootable MMC card with GeeXbox

First prepare the SD card the following way:

• 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

$ cp geexbox-flat-devel-*.arm.eglibc/boot/boot.ini /media/boot
$ cp geexbox-flat-devel-*.arm.eglibc/boot/uImage /media/boot

Next, edit the geexbox-flat-devel-*.arm.eglibc/etc/video file and disable the OpenGL support

OPENGL=no

Finally, copy the geexbox-flat-devel-*.arm.eglibc contents to EXT2 partition.

$ fakeroot cp -dpfa -R geexbox-flat-devel-*.arm.eglibc/* /media/rootfs/

With default environment the IGEP v2 detects the boot.ini script which contains all the necessary instructions for the OS to auto-boot.

Annex: Known issues and solutions

gzip: stdin: invalid compressed data--crc error

Error :

UNPACK   expat
gzip: stdin: invalid compressed data--crc error
tar: Child returned status 1
tar: Exiting with failure status due to previous errors
make: *** [flat] Error 2

Use gzrecover to recover the expat file

$ gzrecover sources/expat/expat-2.0.1.tar.gz
$ mv expat-2.0.1.tar.recovered expat-2.0.1.tar
$ gzip expat-2.0.1.tar
$ mv expat-2.0.1.tar.gz  sources/expat/
