Hi,
I am using a custom carrier board with an iMX8MM and a capacitive touch DSI display.
This is what I am currently running
5.15.148-6.6.1-devel+git.23a8e831749d #1-TorizonCore SMP PREEMPT Tue Jul 9 16:13:47 UTC 2024 aarch64 aarch64 aarch64 GNU/Linux
I have enabled the touch controller in my custom overlay and can see that the driver is loaded and operating. When using evtest the display responds to touches successfully.

I have then tried to run the touch calibration and followed the instructions here: Touch Calibration
However, when I press the crosshairs on the display nothing happens. I have included the output from the container.

It seems as though there is a ‘link’ missing between weston and the driver.
Any help would be much appreciated. Thanks in advance.
