    Default No output on frame buffer (arm target board)

    Hello to Every one,

    I am trying to run qtopia hello world application on arm target board
    but no output in lcd frame device.While It is successfully runnning on qvfb.

    example is :
    int main(int argc, char **argv)
    {

    printf("before app object creation\n");
    QApplication a(argc, argv);
    printf("after app object creation\n");
    printf("before push button object creation\n");
    QPushButton hello("Hello,World", 0);
    printf("after push button object creation\n")
    hello.resize(100,30);
    hello.show();
    return a.exec();

    }
    output :
    before app object creation
    after app object creation
    before push button object creation
    ....
    ......
    ......

    After that application gets hangs.

    Thanks in advance


    Best Regards,
    Devendra
