MX8-DSI-OLED1A touch is not calibrated correctly with IMX8Mini (coordinates are offset)

[leviriley]

I have an imx8mini running yocto imx-image-full using an MX8-DSI-OLED1A touchscreen as input.

Out of the box this worked fine; was able to get touch input from Qt and directly from Wayland, no calibration required.

Had some unexpected destructive testing that required to replacing the display; the replacement is another (brand new) MX8-DSI-OLED1A.

The new display works as a display and does recognize touch; however it is significantly offset from the screen coordinates.

My colleagues and I have used multiple of these out of the box so this does not make sense.

So,
Is this behavior normal?
Is there a standard remedy or calibration sequence?

Cheers,

Levi
