Touch over USB and calibrarion

[arj_don]

Hi,
I have Apalis iMX8 on Ixora carrier board. Connected a resistive touch HDMI monitor and a touch interface over USB.
I built a yocto image by following Build a Reference Image with Yocto Project/OpenEmbedded. I used tdx-reference-multimedia-image for bitbake.

I want to calibrate the touch screen.
I see tools provided by weston,

weston-calibrator

and

weston-touch-calibrator

Which tool needs to be used to calibrate the touch screen.

Thanks.

HI @arj_don ,

You can use weston-touch-calibrator, also note you may need to pass touch device you want to calibrate.
Please check below link

Weston-touch-calibrator problem: no devices listed

Hello, I added a touchscreen to the verdin development board’s usb port, gave the command evtest and the driver was found, as shown below: /dev/input/event3: EloTouchSystems,Inc Elo TouchSystems 2216 AccuTouch® USB I configured the weston.ini and added it to the file: save-calibration.sh in /usr/bin, as per the link: When I give the command weston-touch-calibrator, I get as a response that no touch device was listed. What would be the problem?
