Eclipse IDE is a software development environtment, this software package is very popular because you can extend its functionalities using pluggins. C applications can be compiled in Eclipse using Autoconf tools or Makefile. Autoconf tools can be useful if you want How to develop a huge application with a lot of software dependencies, but this method can be tedious if you want to develop a simple application. manage the kernel modules on Linux
At IGEP v3.0 VM, Eclipse includes Linux tools and Yocto plugin to develop C applications for IGEP firmware as quickly and easily as possible. How do I edit my kernel command line
To follow this How===Included (IGEP GST DSP):==='''AACHEDEC -to you need: > DEC AACHE (OK)'''

There are some requisites to follow this guide=== DM3730: Decode a MP3 file (OK) (ADDED TO REPOSISTORIES)===
*IGEP SDK VM: follow the IGEP SDK SOFTWARE USER MANUAL (chapter 2.3 "Setting up and running the VM")<br> *IGEP Qt Demo: follow the IGEP SDK SOFTWARE USER MANUAL (chapter 6.1 "Create IGEP firmware bootable micro-sd card") and install qt4e-demo-image-igep00x0.tar.bz2 instead IGEP firmware. *[http://www.isee.biz/products/processor-boards/igepv2-board IGEPv2], [http://www.isee.biz/products/expansion-boards/product-igep-berlin IGEP BERLIN] or [http://www.isee.biz/products/expansion-boards/product-igep-paris IGEP PARIS] *MicroSD Card (at least 2Gbytes)<br>'''under contruction'''
== Download and install Qt demo image to a SD<br> ==- Compiled gst-plugins-ugly using yocto tools
Once you have open IGEP SDK VM, launch a terminal and type: <pre>cd Desktop/wget http://downloads.isee.biz/denzil/binary/qt4e-demorpm -igst-plugins-imageugly-igep00x00.tar*.bz2 git clone git://git.isee.biz/pub/scm/igep-tools.gitcd igep-tools/scripts</pre> Insert a SD-Card media and use the igep-media-create script to copy the firmware to SD-Card media, required options are: rpm
*-rpm -i libmad0-mmc </dev/sdX>0.*.rpm
unformated MMC Card - rpm -i gst-plugins-ugly-mad-0.*.rpm
*-gst-image <filename>launch filesrc location=sample.mp3 ! mad ! volume volume=0.25 ! alsasink

*gst-launch -machine <machine>-gst-debug-level=3 filesrc location=sample.ra ! rmdemux ! volume volume=0.25 ! alsasink
specify the machinehttp://www. Options are igep0020, igep0030 or igep0032<br> superluminal.com/andalib/ra/listen.ra
For example, assuming the SD card device takes "/dev/sdf" and you have and IGEPv2 board (igep0020), type: <pre>./igepgst-mediaplugins-create ugly-rmdemux-mmc /dev/sdf --machine igep0020 -0.10.19-image /home/jdoe/Desktop/qt4e-demo-image-igep00x0r1.tararmv7a.bz2</pre> This should give you a bootable SD-card<br>rpm

=== Download and extract IGEP root filesystem ===
ISEE mantains two rootfs builded with Yocto tools:
*IGEP firmware: default software shipped in all IGEP Boards. It comes with some documentation and tools, so you need to uncompress again to extract rootfs
<pre>wget http://downloads.isee.biz/denzil/binary/igep_firmware-yocto-1.2.1-1.tar.bz2
tar jxf igep_firmware-yocto-*.tar.bz2
cd igep_firmware-yocto-*

sudo tar jxf demo-image-sato-igep00x0.tar.bz2 -C /srv/{your_rootfs_dir} </pre>
*Qt demo: demo filesystem with Qt libraries and examples
<pre>wget http://downloads.isee.biz/denzil/binary/qt4e-demo-image-igep00x0.tar.bz2
sudo mkdir /srv/{your_rootfs_dir}
sudo tar jxf qt4e-demo-image-igep00x0.tar.bz2 -C /srv/{your_rootfs_dir}</pre>
=== Configure NFS Server ===
*Install nfs-kernel-server:
<pre>sudo apt-get install nfs-kernel-server </pre>
*Make directory exports.d:<br>
<pre>sudo mkdir /etc/exports.d </pre>
Edit /etc/exports file, add the following line and save the changes:
<pre>/srv/{your_rootfs_dir} *(rw,sync,no_subtree_check,no_root_squash)</pre>
Export NFS file system:
<pre>sudo exportfs -a</pre>
== Set up NFS at IGEP Board ==
=== MicroSD boot ===
Configure igep.ini file located at boot partition:<br>
*Comment MMC boot:
<pre>; --- Configure MMC boot ---
;root=/dev/mmcblk0p2 rw rootwait</pre>
*Add NFS configuration:
<pre>; --- Configure NFS boot ---

root=/dev/nfs
nfsroot=192.168.5.10:/srv/{your_rootfs_dir}</pre>
=== Flash boot<br> ===
Boot IGEP with a MicroSD card without NFS support. Modify igep.ini located in flash memory:
<pre>mkdir /tmp/temp
mount -t jffs2 /dev/mtdblock1 /tmp/temp </pre>
Now, mtdblock1 partition is mounted at /tmp/temp directory:<br>
*Comment JFFS2 FS boot:
<pre>; --- Configure JFFS2 FS boot ---
;root=/dev/mtdblock2
;rootfstype=jffs2</pre>
*Add NFS configuration:
