I have managed to develop Qt application and compile them for Linux platform with TI-SDK.

I am interested in n=how Qt used LCD Controller block of AM335X to display the images, i mean device driver layer. Which files(location of the files in TI_SDK) should i refer? I want to understand how Qt accesses Linux Frame buffer?

Qt uses the linuxfb plugin to talk to the fbdev driver for the AM335x lcdc. Take a look at the Sitara Linux LCDC page for more info on the fbdev driver for the LCDC.

This wiki has some tips on how to set the Qt display plugin.
