I'm trying to use touchscreen with am335x. First I use debian and the touchscreen works well. But when I use the linux built from linux sdk 5.03, the touchscreen didnot work correctly.I used one same devicetree file.
When I running linux of SDK 5.03, the system enter matrix gui , the touchscreen display ok, and I can use mouse to click and start application. But when I try to touch the screen, it does not work. Then I modified the tsc driver 'drivers/input/touchscreen/ti_am335x_tsc.c'. In funtion 'titsc_irq' I print the touchscreen's coordinates, it shows the coordinate when I touch the screen. So , the screen actuly works but the system didnot respons. How to solve this problem?
