I built qt-everywhere-opensource-src-4.8.3 and tslib for mini210s board. When I built a example and tested it, Image is displayed but cannot move the cursor with a stylus. Thanks TanLe
mini210s touchscreen problem
As a first step, I would suggest finding out what /dev the stylus is attached to and test it by: cat /dev/whatever_your_stylus_node_is and move the stylus around the screen. See anything? Maybe, show your list of environment variables (printenv)
