Hello All FriendlyARM developers
Here's the deal. I know Qtopia Core is old, I know Qt Embedded is old,
several developers mentioned, but I have a Mini2440 FriendlyARM based
embedded device with the following characteristics:
- CPU: 400 MHz Samsung S3C2440 ARM926T
- RAM: 64 MB
- LCD: 3.5 inches with 240*320 pixels
Mainly there are a couple of pre-installed software on the board: Linux
Kernel 2.6.32.2 and Qtopia 2.2.0.
After turning on the device the Qtopia is executed. I tried to escape from
Qtopia so I comment out the last lines of /etc/init.d/rcS:
/bin/qtopia &
echo " " > /dev/tty1
echo "Starting Qtopia, please waiting ..." > /dev/tty1
My first question is: Is it possible to un-install Qtopia from the
board and install newer version of Qt Embedded like Qt Embedded 4.8? If the
answer is positive, how?
Currently I have an installed version of Qtopia core opensource 4.3.5 on my
development computer (in cross-compiling terminology the "build" and "host"
machine) I successfully configured, built and installed it for
cross-compiling for ARM target machine using arm-linug-g++ family
toolchain. The software is located at default path:
/usr/local/Trolltech/QtopiaCore-4.3.5-arm
I configured Qtopia with the following command and options:
./configure -static -exceptions -no-qt3support -v -embedded arm -xplatform
qws/linux-arm-g++ -qt-libpng -system-libjpeg -qt-libtiff -qt-zlib
Now when I try to run a typical program like hello, world with a push
button or similar widgets, with the following command:
./hello_world -qws
I have a frozen screen, without any feedback, the board pen doesn't work,
the touchscreen doesn't work and worse my 240*320 window is rotated by 90
degree.
My another question is: Are all because I forgot to use the
-qt-mouse-tslib option in configuration. by googling Qtopia environment
variables and inspired by this
http://www.sereno-labs.com/qt-4-6-2-installation-procedure-for-friendlya...
I put the following environment variable in a shell script:
export TSLIB_TSEVENTTYPE=INPUT
export TSLIB_CONSOLEDEVICE=none
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_TSDEVICE=/usr/local/lib/ts
export TSLIB_CALIBFILE=/etc/pointercal
export TSLIB_CONFFILE=/usr/local/etc/ts.conf
export TSLIB_PLUGINDIR=/usr/local/lib/ts
export LD_LIBRARY_PATH=/usr/local/Trolltech/QtopiaCore-4.3.5-arm/lib
export QTDIR=/usr/local/Trolltech/QtopiaCore-4.3.5-arm
export QWS_MOUSE_PROTO=tslib:/usr/local/lib/ts
export
QT_QWS_FONTDIR=/usr/local/Trolltech/QtopiaCore-4.3.5-arm/lib/fonts
export QWS_DISPLAY=LinuxFB:mmWidth=55:mmHeight=73
export TSLIB_PLUGINDIR=/usr/local/lib/ts
export QTDIR=/usr/local/Trolltech/QtopiaCore-4.3.5-arm
export QWS_SIZE=240x320
and ran at the board, before running program, unfortunately there is no
improvement.
FYI, I have just 2 input devices: /dev/input/event0 and mice there is no
/dev/input/touchscreen
about the unwanted rotated screen, I exchanged mmWidht and mmHeight or in
QWS_SIZE, I excahnged width and height without any success. Do I have to
use Transformed:Rot90. What is the meaning of Transformed:RotX at all?
Thank you in advance for your response, I am confused with a lot of
concepts and I can't figure out, what should I do.
