Hi There,
Im using the mini2440 and im having a VERY SERIOUS proplem!!
I have compiled Qt-Embedded 4.6.1 for the mini 2440.
Now my issue is that the Performance of the GUI is really bad, it takes up
to 5 seconds to open one window from another window, and atleast 1 second
till it reacts on pressing a QButton, also it takes up to 15 secs to start
a Qt application.
The application uses up 1t 100% CPU and like 70% of the memory
Whats the ebst way to accelerate this?
im using the fb to display and this are my config options:
./configure -v \
-embedded arm -xplatform qws/linux-arm-g++ -prefix /usr/qt \
-nomake examples -nomake demos -opensource \
-no-accessibility -no-sql-sqlite -no-phonon -no-phonon-backend -no-qt3support \
-no-scripttools -no-mmx -no-3dnow -no-sse -no-sse2 -no-cups -no-dbus -no-glib \
-qt-libtiff -qt-libpng -qt-libmng -qt-libjpeg -qt-gfx-linuxfb -qt-mouse-tslib -qt-gfx-qvfb \
-shared –debug
if i run without -debug the programms failw ith Segmentation fault based on the compiler optimations
Im currenty having the QT/E libs on the sdcard and they are like 80MB,
which leads me to my 2end not so importaint qestion atm.
Is there alreaddy a Version of Qt-e on the device? and if so how can i use
it?
Whats the best way to shrink down the Qt-e libs to the minimal/requred size
to fit into the 128 MB of flash memory?
I would really appreciate any HELP!
THANKS ALOT!!
