There are some requisites to follow this guide==== DM3730: Decode an WMA audio file (OK)====
*IGEP Board*MicroSD card with the latest IGEP Firmware Yocto*PC*IGEP remote terminal, using a serial cable or Ethernet communication<pre>bitbake gst-ffmpeg</pre>
* Boot your IGEP Board using a microSD card* Get a remote terminal* Log as a root user* Mount flash memory partition using the following commands'''Into repositories (base plugins):<pre>mkdir /tmp/mtdblock1mkdir /tmp/mtdblock2mount -t jffs2 /dev/mtdblock1 /tmp/mtdblock1mount -t jffs2 /dev/mtdblock2 /tmp/mtdblock2</pre>* Create a backup directory and backup your flash memory:<pre>mkdir /home/root/backuptar -cvf /home/root/backup/igepinikernel.tar /tmp/mtdblock1/tar -cvf /home/root/backup/rootfs.tar /tmp/mtdblock2</pre>*Shutdown your system'''

First of all, you need to get a IGEP X-Loader image (named by default MLO), you can download a compiled IGEP X-loader image from [http://labs.isee.biz/index.php/The_IGEP_X-loader#Pre-Compiled_Binaries this article].== BASE0033 CONNECTOR SUMMARY TABLE==
Once you extract MLO file copy to microSD rootfs partition inside backup folder create before.== Configure a static IP using the same private network range ==
=== Restore your firmware image to flash memory ==='''under construction''' IGEP Firmware Yocto uses the following Ethernet network configuration (IP addresses)
* Boot your IGEP Board using the same microSD used This Ethernet network configuration is really useful when you backup your work using a Linux operating system* Get a remote terminal* Log as a root user* Erase flash memory using the following commands:<pre>flash-eraseall /dev/mtd0flash_eraseall /dev/mtd1flash_eraseall /dev/mtd2</pre>* Mount flash memory partition using the following commands:<pre>mkdir /tmp/mtdblock1mkdir /tmp/mtdblock2mount -t jffs2 /dev/mtdblock1 /tmp/mtdblock1mount -t jffs2 /dev/mtdblock2 /tmp/mtdblock2</pre>* Restore igeplike IGEP SDK Virtual Machine.ini, Kernel Because you use eth0 device to communicate easily with your board and rootfseth0:<pre>cd /tar xvf /home/root/backup/igepinikernel.tartar xvf /home/root/backup/rootfs0 device to get Internet acces using dhcp protocol.tar</pre>* Copy IGEP X-Loader binary to flash memory:<pre> writeloader -i /home/root/backup/MLO /dev/mtd0</pre>* Shutdown your system
=== Test results===But some scenarios this network configuration is not useful, for example: if you use a non-Linux operating system, connect to two IP private range interfaces is not simple. This How-to can be useful to
Once you shutdown your system,l extract your microSD card (Make diagram one: IGEP and bootup Linux defualt communication. Diagram 2 IGEP Board using flash memory. Your old system image should be executed.and other SO alternative configuration)
