Setting up a 7 in touch lcd (800x480) with IMX8 MINI (imx8mmevk) in Yocto

I have a Yocto image for imx8 mini with the wayland and weston and I'm trynig to set up a 7 inch HDMI touch LCD with 800x480 resolution as the display, but no success so far. The image is working fine in HDMI FullHD display though.

I should also mention that in the above LCD we have the NXP icon at the begining of the Yocto image and also when the image boots up the screen turns white which I believe is because of the app I've set to run on the board using services. So it seems that weston is running but the render resolution is larger than 800x480 and it seems that only a part of the contents are being displayed.

How can I fix this problem?
