== Overview ==How to manage the kernel modules on Linux
This guide can be helpful to learnt to develop Qt applications under IGEP Boards. Qt is a cross-platform application framework that is widely used for developing application software with a graphical user interface, and also used for developing non-GUI programs such as How do I edit my kernel command-line tools and consoles for servers. You can get more information [http://qt.nokia.com/ here].
There are some requisites to follow this guide===Included (IGEP GST DSP): ==='''AACHEDEC -> DEC AACHE (OK)'''
*[http://iseedownload.biz/component/zoo/item/igep-virtual-machine-sdk-yocto IGEP SDK VM]: follow the IGEP SDK SOFTWARE USER MANUAL (chapter 2.3 "Setting up and running the VM")<br> *[http://downloads.isee.biz/denzil/binary/qt4e-demo-image-igep00x0.tar.bz2 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://wwwwavetlan.isee.biz/products/processor-boards/igepv2-board IGEPv2], [http:/com/www.isee.bizSVV/productsMedia/expansion-boardsHTTP/productFAAC-igepHE-berlin IGEP BERLIN] or [http://wwwAAC.isee.biz/products/expansion-boards/product-igep-paris IGEP PARIS] *MicroSD Card (at least 2Gbytes)<br>aac
Once you have open IGEP SDK VM, launch a terminal and type: <pre>cd Desktop/wget http://downloads.isee.biz/denzil/binary/qt4eoutofthebox-demo-image-igep00x0.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: ok
*--mmc </dev/sdX>--
unformated MMC Card '''MP3DEC -> DEC MP3 (AUDIO ERRORS)'''
*-Followed README file from ISEE -image <filename>IGEP DSP - GST + DMAI Support Package 3.40.00
specify file used to create the bootable SD cardhttp://www. stephaniequinn.com/Music/Canon.mp3
*gst-launch -machine <machine>-gst-debug-level=2 filesrc location=Canon.mp3 ! TIAuddec1 codecName=mp3dec engineName=codecServer ! volume volume=0.25 ! alsasink sync=false
specify the machine. Options are igep0020, igep0030 or igep0032<br> '''Random fatal bit error'''
For example, assuming '''mp3-plugin doesn't resolve the SD card device takes "/dev/sdf" and you have and IGEPv2 board (igep0020), type: <pre>./igep-media-create --mmc /dev/sdf --machine igep0020 --image /home/jdoe/Desktop/qt4e-demo-image-igep00x0.tar.bz2</pre> This should give you a bootable SD-card<br> error'''
== Prepare Qt demo image ==----
Qt demo image is a root filesystem build by Yocto that contains Qt embedded libraries, also this image has some Qt examples for testing purposes. '''G711DEC -> DEC PCM uLAW (speech) (NOT TESTED)'''
This image doesn't have openssh and gdbserver, so we should install these packages to develop Qt applications. Open a shell prompt using serial communication ''G711ENC -> ENC PCM uLAW (IGEP SDK SOFTWARE MANUAL chapter 3.1 "Using serial mode"speech) and type the following commands: <pre>zypper refzypper in opensshzypper in gdbserver</pre> Now you can connect between IGEP and VM using SSH protocol:<br> <pre>ssh root@"IGEP IP for example: 192.168.5.1"</pre> == Using Qt Creator ==(NOT TESTED)'''

'''<sup>Click to enlarge image</sup>''' IGEP Firmware Yocto uses the following Ethernet network configuration (IP addresses)
= Set up a NFS between IGEP Board and IGEP VM (check at prove it) =*eth0 − 192.168.5.1*eth0:0 − assigned via dhcp.
== Overview ==This Ethernet network configuration is really useful when you work using a Linux operating system like IGEP SDK Virtual Machine. Because you use eth0 device to communicate easily with your board and eth0:0 device to get Internet acces using dhcp protocol.
Network File System (NFS) But some scenarios this network configuration is not useful, for example: if you use a Distributed file non-Linux operating system protocol originally developed by Sun Microsystems in 1984, allowing a user on a client Computer connect to access files over a network in a manner similar to how local storage two IP private range interfaces is accessednot simple. NFS, like many other protocols, builds on the Open Network Computing Remote Procedure Call (ONC RPC) system. The Network File System is an open standard defined in RFCs, allowing anyone This How-to can be useful to implement the protocol. More information [http://en.wikipedia.org/wiki/Network_File_System here].<br>
