[[Image:Qtlogo.png|right]] This page contains instructions how to set up
* '''Qt Embedded''' (running natively on the Linux frame buffer, but without OpenGL support)
* '''Qt/X11''' (running on X11 server, with OpenGL support)
for Bluetechnix i.MX53 modules.

= Software versions =

* Bluetechnix Linux BSP release 1.4
**based on Freescale Linux Board Support Package
* Qt Embedded 4.6.0
** LTIB will handle the download

See the [[Software User Manual (CM-i.MX53)|Software User Manual]] how to install LTIB (i.e., Freescale and Bluetechnix Linux packages), if you have not done so yet.

= Instructions =

== Host packages ==
* We need to install some additional host packages.
sudo apt-get -y install gettext libgtk2.0-dev rpm bison m4 libfreetype6-dev
sudo apt-get -y install libdbus-glib-1-dev liborbit2-dev intltool
sudo apt-get -y install ccache ncurses-dev zlib1g zlib1g-dev gcc g++ libtool
sudo apt-get -y install uuid-dev liblzo2-dev
sudo apt-get -y install tcl dpkg
sudo apt-get -y install libx11-dev libpng-dev libjpeg-dev libxext-dev x11proto-xext-dev qt3-dev-tools-embedded libxtst-dev
sudo apt-get -y install bison flex libqt4-dev libqt4-opengl-dev libphonon-dev libicu-dev libsqlite3-dev libxext-dev libxrender-dev gperf libfontconfig1-dev libphonon-dev g++

== Multimedia Codec Libraries ==
* Download the i.MX53 hardware codecs package from the [https://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX535&nodeId=018rH3ZrDR988D&fpsp=1&tab=Design_Tools_Tab Freescale website] (open the ''Codecs and other Algorithms'' menu).
IMX_MMCODECS_11.05.tar.gz
* Unpack it and copy the following files to ''/opt/freescale/pkgs/'':
IMX_MMCODECS_11.05/Ltib Files/fsl-mm-codeclib-2.0.1.tar.gz
IMX_MMCODECS_11.05/Ltib Files/gst-fsl-plugin-2.0.1.tar.gz
* Extract the file
IMX_MMCODECS_11.05/Ltib Files/ltib_spec_patch_base_on_11.05.01.zip
* Copy the resulting files to (Important: If you are using BSP release 1.6 or newer, don't copy the ''gst-fsl-plugin.spec'' file.)
ltib/dist/lfs-5.1/fsl-mm

== LTIB configuration (Qt Embedded) ==
* In ''ltib/'' folder, start LTIB's configuration dialog:
./ltib -c
* Go to
Package list --->
* Select the following packages:
[*] amd-gpu-bin-mx51
[*] libz160-bin
Freescale Multimedia Plugins/Codecs --->
[*] fsl-mm-codec-libs
[*] gstreamer-fsl-plugins
[*] fontconfig
[*] freetype
[*] gstreamer
[*] gstreamer-plugins-base
[*] gstreamer-plugins-good
[*] gstreamer-plugins-bad
[*] gstreamer-plugins-ugly
[*] Liberation fonts
[*] libjpeg
[*] libpng
[*] liboil
[*] libxml2
[*] mysql
Qt --->
Qt (...) --->
(X) Qt Embedded
[*] Phonon
[*] zlib
* Exit from LTIB and save your new configuration (you will be asked).
* LTIB will build Qt Embedded now.

== LTIB configuration (Qt X11) ==
NOTE: We have marked differences to ''Qt Embedded'' configuration in green.
* In ''ltib/'' folder, start LTIB's configuration dialog:
./ltib -c
* Go to
Package list --->
* Select the following packages:
[*] amd-gpu-x11-bin-mx51
[*] libz160-bin
Freescale Multimedia Plugins/Codecs --->
[*] fsl-mm-codec-libs
[*] gstreamer-fsl-plugins
[*] fontconfig
[*] freetype
[*] gstreamer
[*] gstreamer-plugins-base
[*] gstreamer-plugins-good
[*] gstreamer-plugins-bad
[*] gstreamer-plugins-ugly
[*] Liberation fonts
[*] libjpeg
[*] libpng
[*] liboil
[*] libxml2
[*] mysql
X11 --->
Install X11 --->
(X) X.Org 7.5
X11 libraries and packages --->
[*] libICE
[*] libSM
[*] zlib
* Exit from LTIB and save your new configuration (you will be asked).
* LTIB will build Qt for X11 now.

== Error handling ==

The following errors were observed, here is how to handle them:

;LTIB cannot download the ''qt'' package.
:Download the file from here: https://get.qt.nokia.com/qt/source/qt-everywhere-opensource-src-4.6.0.tar.gz
:and save it to ''/opt/freescale/pkgs/''

;ubinize complains that there is not enough space in the UBIFS partition.
:If you do not plan to set up the NAND flash with Qt Embedded, you can ignore this error. But if you plan, edit the file
bin/ubifs_ubinize_tmpl.ini
:Change the parameter
vol_size
:You also have to change the NAND flash's rootfs partition's size in the Linux kernel code. Open the platform file for the module you have:
rpm/BUILD/linux/arch/arm/mach-mx5/mx53_qseven.c
rpm/BUILD/linux/arch/arm/mach-mx5/cmimx53.c
:and increase the size of the ''nand.rootfs'' partition (given in bytes):
static struct mtd_partition nand_flash_partitions[] = {
[...]
.name = "nand.rootfs",
.offset = MTDPART_OFS_APPEND,
.size = 256 * 1024 * 1024},
[...]
};

== Start Qt Embedded ==
[[Image:Pathstroking.png|right|thumb|Path Stroking]]
[[Image:Fluidlauncher.png|right|thumb|Fluid Launcher]]
*Bring Qt Embedded to the target module
**by rebooting (if you mount the root file system via NFS from your host machine) or
**by setting up a new SD card (using the ''setup_sdcard.sh'' script).

*After booting Linux on the MX53 module, set Qt's font path:
export QT_QWS_FONTDIR=/usr/lib/fonts/

*'''Pathstroke demo application'''
cd /usr/local/Trolltech/demos/pathstroke/
./pathstroke -qws

*'''Fluid Launcher demo'''
cd /usr/local/Trolltech/demos/embedded/fluidlauncher
./fluidlauncher -qws

*LTIB installs a whole host of demos and examples which you may browse through:
/usr/local/Trolltech

== Start Qt/X11 ==
*Bring Qt/X11 to the target module
**by rebooting (if you mount the root file system via NFS from your host machine) or
**by setting up a new SD card (using the ''setup_sdcard.sh'' script).

*After booting Linux on the MX53 module, start the X-server (assuming you have a keyboard connected as ''/dev/input/event2''):
export DISPLAY=:0.0
Xfbdev -mouse mouse,,device=/dev/input/mice -keybd keyboard,,/dev/input/event2 &

*'''Pathstroke demo application'''
cd /usr/local/Trolltech/demos/pathstroke/
./pathstroke -qws

*LTIB installs a whole host of demos and examples which you may browse through:
/usr/local/Trolltech

== OpenGL comparison ==

The ''pathstroke'' demo application features the '''Use OpenGL''' button which lets us easily switch on/off using OpenGL from the MX53 internal GPU.

Here is a short comparison we did with a CM-i.MX53-C-C-Q24S1024F4N2048 running in a DEV-i.MX53 development board, using default HDMI output of 1280x720 pixels, frame buffer color format RGB565.

''fbset output'':
mode "1280x720-60"
# D: 74.505 MHz, H: 44.774 kHz, V: 59.859 Hz
geometry 1280 720 1280 2160 16
timings 13422 192 64 3 20 128 5
