We are working on porting JB4.3 onto our i.MX6-based customized board. The board is desinged being based on a i.MX6 SABRE.
We've done a lot so that almost everything is working except touchscreen. When the device is boot-up, a white circle shows on a screen.
This is different from what we can enable in 'Settings-Developer options-Show touches'. In order to click something, first I have to move this circle by dragging it.
Then have to double click the circle to make 'single-touch'. This is very wierd and never have seen before when I developed using i.MX5 and GB.
Do you have any idea what this feature is?
