=== Extending the root file system ===
NELK root file system derives directly from the one delivered along with TI EZSDK. In order to enrich it by installing new pre-built packages, well-known opkg tool comes to help.
The following instructions describes how to configure opkg in order to add more packages in order to provide a richer set of libraries, tools and applications.
To configure opgk to retrieve pre-built packages from angstrom repository, please follow these instructions:
<pre>
$ echo "src/gz angstrom-base http://www.angstrom-distribution.org/feeds/unstable/ipk/glibc/armv7a/base" >> /etc/opkg/opkg.conf
$ opkg update
</pre>
Please note that '''packages provided by angstrom repository are not optimized for DM8148 media hardware blocks such as video codec'''. For this reason, pay attention to not replace DM8148-optimized applications and libraries provided by default root file system.
