Hey,
thank you for the reply. Yes exactly, the touchscreen results not calibrated after each reboot.
To fix it, at the moment, I have created a custom Torizon OS that replace the touchscreen.rules file with the one written by me contianing the calibration matrix like shown below:
SUBSYSTEM=="input", KERNEL=="event[0-9]*", ENV{ID_INPUT_TOUCHSCREEN}=="1", ENV{LIBINPUT_CALIBRATION_MATRIX}="4.081606 0.108260 -0.021712 0.029122 6.689587 -0.001553"
