This tutorial is a translation of a French tutorial we wrote on our robotic [http://as.tech.free.fr/wiki/index.php?title=Cr%C3%A9er_un_environnement_de_d%C3%A9veloppement_pour_l%27OMAP3530 web site]. Sorry for the English, feel free to correct mistakes.

This tutorial was written for the [http://wwwlabs.igep-platformisee.combiz/index.php?option=com_content&view=article&id=46&Itemid=55 /IGEP_Technology_devices_revisions ''igep revB''] board, but it is transposable to other ''OMAP3530'' boards (above all for the ''DSP'' part). It is a summary (with some adaptations) of several tutorials found on Internet (see [[How to setup a development environment#References|References]]). All files will be installed in the $HOME directory. __TOC__ {{Message/Obsolete|Link=Visit the [[IGEP SDK Virtual Machine]] for updated information}}

This section describes how to obtain the [http://www.pokylinux.org/ ''Poky''] distribution. This is the distribution shipped with the ''igep'' board; it is based on [http://wikiwww.openembedded.netorg/index.phpwiki/Main_Page ''Open Embedded''].
The first thing to do is set ''Bash'' as default ''sh'' ''shell'':
We will see in section [[How to setup a development environment#Boot_on_the_rootfs_and_the_kernel|''Boot'' on ''rootfs'' and kernel]] how to use it. Yet, ''bitbake'' will download by default the kernel "linux-omap-2.6.28.10-igep0020b-0" which is not the last one provided by ''ISEE''. See section [[How to setup a development environment#Kernel_compilation|Kernel compilation]] to compile another version.
TODO: modify ''recipes'' to download another kernel version

</pre>
Thus, the size is 0x40000=265KB256KB.
==== Copy from ''uboot'' ====

And now reboot. In case of errors (such as ''bad crc'' on the ''kernel'' for example), it is necessary to reflash all, see [http://wikilabs.myigepisee.combiz/trac/wikiindex.php/HowToUpgradeTheFactoryFirmware Update_the_PRE-INSTALLED_software_image_to_a_current_release this].
=== Copy kernel and ''rootfs'' in memory card ===
The variables OSINC_GENERIC and OSINC_PLATFORM allow to setup the directories where ''DSPLINK'' will look for ''.h'' files.
=== Librairies Libraries ===
By defualt, ''DSPLINK'' is searching the libraries in the directories:
