Before starting, make sure you have enabled touchscreen support in the device tree of the STK
To set up the Touchscreen on STKa335x or STKa6x start with a simple fb_test to make sure the device is working properly.
After startup, run the command
fb_test
which launches a variety of tests, consisting of both black and white and coloured images.
Afterwards, calibrate the Touchscreen with
ts_calibrate
Sometimes the system does not recognize that a touchscreen device is connected. If so, you will have to export Tslib before starting the calibration. Should this be the case, run the command “export TSLIB_TSDEVICE=/dev/input/event2”, then recalibrate.
To make sure everything is working as intended, run
ts_test
