<br>

= Prepare the Enviroment<br>  =

Untar the file cg6x_7_0_1.bz2 (located in tools/code_generation_tools/) in the /usr/local/ti directory if it not exist first you should create it.<br> 
<pre>&gt;&gt;sudo mkdir /usr/local/ti

&gt;&gt;cd /usr/local/ti

&gt;&gt;sudo tar xvfj  cg6x_7_0_1.bz2</pre>
If it's necessary add read permissions to all files:
<pre>&gt;&gt; sudo chmod a+r /usr/local/ti/cg6x_7_0_1</pre>
It's a requisite configure your kernel properly for build this package:
<pre>source /usr/local/poky/eabi-glibc/environment-setup-arm-none-linux-gnueabi
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- igep0020_defconfig
</pre>
<br> 

= How to Build<br>  =

You should edit the file Rules.make for edit the package path, linux kernel&nbsp; and toolchain location:<br>

----

You have two options: build all or every package individually.<br> 

a) All packages 

make 

b) One package 

make &lt;package_name&gt; 
<pre>make dmai

make gst

make dsplink
</pre> 
For clean the build you should execute: 

make clean 

or 

make &lt;package_name&gt;_clean 

such: 
<pre>make dmai_clean

make dsplink_clean

make gst_clean
</pre> 
= Install  =

Copy the "target" directory inside your IGEP board. 

Inside IGEPv2 board you should copy the gst plugin inside the plugins directory, normally inside /usr/lib/gstreamer-0.10 

We included some files for configure, load and unload the kernel modules as loadmodules.sh and unloadmodules.sh 

You should call the loadmodules.sh script before you can execute gstreamer. 

<br> 

== Uboot Setup  ==

You should configure the max kernel memory to 430MBytes for do it you should pass the variable mem=430M to the kernel. 

<br> 

= Download<br>  =

The package be available in the IGEPv2 download area.

= Issues detected in this version  =

*The package binaries included in this version be compiled for TI Arago Kernel 2.6.32. 
*Press Control+C when video plays hangs the DSPLink module kernel and the board should be restarted. 
*Audio and Video are not properly syncronized if the audio sampling rate it's different than 48Khz.&nbsp;<br> 
*This version be not compatible with kernels over 2.6.33 due compile issues. 
*The path file cannot contain any "." dot due a xdctools BUG. 
*make clean (dsplink) not work properly and it's necessary to do a make dsplink_clean for ensure all it's compiled correctly.
