Linux/AM5728: touch screen : ft5x06

Part Number: AM5728

Tool/software: Linux

Hi,

I am using ft5x06 touch, I have integrated the edt,ft5x06 driver and i have got the touch interrupts.

I have used the ts_calibrate and ts_test applications, those are pretty fine according to me.

Now, I have tried with the touch with qt applications, Got few error as follows,

root@am57xx-evm:/usr/share/qt5/examples/quick/touchinteraction# ./touchinteraction -platform eglfs
failed to load module: /usr/lib/gbm/gbm_dri.so: cannot open shared object file: No such file or directory
failed to load module: /usr/lib/gbm/gbm_gallium_drm.so: cannot open shared object file: No such file or directory
loaded module : gbm_pvr.so
found valid GBM backend : gbm_pvr.so
No modes available for output "HDMI1"

^Croot@am57xx-evm:/usr/share/qt5/examples/quick/touchinteraction#

How to resolve those errors ?

Please suggest QT based touch application like widgets provided in EVM design.

    Hello,

    What is the PSDK version that you are using here?
    I have tested this demo on my side and it is working fine. Here are the results:
    root@am57xx-evm:/usr/share/qt5/examples/quick/touchinteraction# /etc/init.d/weston stop
    Stopping Weston
    root@am57xx-evm:/usr/share/qt5/examples/quick/touchinteraction# ./touchinteraction -platform eglfs
    Unable to query physical screen size, defaulting to 100 dpi.
    To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).


    If you do not want to stop weston you could run it this way:


    root@am57xx-evm:/usr/share/qt5/examples/quick/touchinteraction# ./touchinteraction
    Using Wayland-EGL
    wlpvr: PVR Services Initialised
    Using the 'xdg-shell-v5' shell integration
    ...

    Hi Margarita,

    Thanks for the reply.

    I m using PSDK 04.02.00.09 version.

    root@am57xx-evm:/usr/share/qt5/examples/quick/touchinteraction# /etc/init.d/weston stop

    -sh: /etc/init.d/weston: No such file or directory

    root@am57xx-evm:/usr/share/qt5/examples/quick/touchinteraction#

    I cannot run without mentioning the platform.

    root@am57xx-evm:/usr/share/qt5/examples/quick/touchinteraction# ./touchinteraction
    Failed to create display (No such file or directory)
    root@am57xx-evm:/usr/share/qt5/examples/quick/touchinteraction#

    While running with the -platform eglfs, I m getting the below mentioned screen. I can able to get into the each menu.

    But after that the functionality is not proper.

    May i know the supporting packages required to run the application ?

    Hello,

    Are you able to enter, let say in "Multipoint flames"?

    Hello,

    I tried the exit button and it is working. Could you try on the latest 5.x release?

    I have ran evtest on my side. The above is the result when I select first option and then press exit.

    Here is our ". How to Recalibrate the Touchscreen" guide. Please notice there are Non-Weston based Graphic System and Weston based Graphic System.

    Hope this helps.
