hello guys i am working on mini2440 3.5" with the factory yaffs and linux 2.6.32 kernel.i have some questions- i also have run qt-4.5 examples on my current board configuration.But the problem is my touch screen has stopped responding.my question 1.)Is it stupid trying to execute qt-4.5 examples on qt-2.2.0 configuration.i have changed the Qt dir path though.I thought of changing the Qt dir and ts lib on the mini keeping the original YAFFS.Is that possible? 2.)Y my touch screen has stopped working .Is it becoz i'm executing qt-4.5 examples?if yes then- 3.)how is ts lib associated with QT? or are they independent 4.)Qt-4.5 examples execute on my board but are oversized,i mean i cannot see the complete picture.like when i execute colliding mice my 3.5" screen cannot show the whole application.Is that becoz the original example was compiled for 7"??if yes then- 5.) how at compile time can we tell the crosscompiler to compile the thing for different touchscreen sizes? distress call somebody help?
