Hi, Actually I have posted what I have discovered. The problem I faced was with 10 inch screen, with theLCD7CAPE every thing works fine. Touch screen has a capacitance, and there is a charging cycle, which is used in initial touch detecting. If the charging faze is too short, touch screen voltage is too low and this is detected as touch event. I have changed CHARGEDLY_OPENDLY from 1 to 10 (ti_am335x_tscadc.h), 1 is definitely too short.
