QT 4.7.3 / no Image / Console on LCD?

Hi @all,

i'm a beginner with the mini2440 board (actually i got a sky2440, but its
almoste the same.)
the board + 4.3" LCD works great with the delivered uboot/kernel/image with
qtopia 2.2

now i cross-compile QT embedded 4.7.3 without erros and copied the libs and
bins to the mini2440. i changed the startupscript /etc/init.d/rcS and
the script at /bin/qtopia to start the "mainwindow" from QT demos instead
of the "qwe" from qtopia.

after the TS_calib window (which works perfect) my display doenst show
everything (the ts_calib image is still on the display) but it should start
the "mainwindow"

when i telnet to the mini2440 and run the "mainwindow" manually theres no
error, just a echo about the screen size (480x272). but also no image on
the display.

is there a way to show the shell / errors on the LCD? so that i could see
if theres a error and run commands when i have a usb-keyboard attached?

okay there was actually an error after all,no answer needed :)

Hi antifish,

Could you please tell me about the steps to compile the Qt, or can you send
me the compiled qt?

Hi Jose,

i'm still struggling with diffrent toolchains, rootfs, bootloader etc etc
:)

i think it really depends which toolchain you use to try compile the
QT4.7.3

but what works is this way:
  - install buildroot with this tutorial
  http://pauljones.id.au/blog/2010/07/using-buildroot-on-a-mini2440/

  - after the "make mini2440_defconfig"
    start the menuconfig, go to Toolchain options, select C++ support

  - go to Target Options, Graphic Libraries, select QT
    in QT options, select the accept free license and don't forget to add
TSLIB in the Mouse options

  - exit menuconfig, save changes

MAKE :) (need hours...)

after that you have a uImage (Kernel for U-Boot), rootfs (as tar and as
jffs2)with the qt libs included and a working toolchain in
../buildroot/output/host/usr/bin
as i dont use u-boot (and the kernel builded by buildroot has no nand
support) i only use the generated toolchain and the QT4.7.3 libs in
../buildroot/output/build/qt...
