Hi @AhmedMobarez ,

In your overlays.txt:

  • There is an entry named apalis-imx8x_lvds_overlay.dtbo (notice the x after 8) which does not apply to the Apalis iMX8. I think you meant apalis-imx8_lvds_overlay.dtbo.

  • While you referenced all the correct .dtbo files (considering the correction above), the order in which you write them matters, as each overlay file is applied sequentially. So the content of your overlay.txt should be:

fdt_overlays=apalis-imx8_lvds_overlay.dtbo apalis-imx8_atmel-mxt_overlay.dtbo display-lt170410_overlay.dtbo

toradex_5.4-2.3.x-imx refers to the Downstream Linux Kernel from NXP and it is the default version used in TorizonCore for our iMX8/iMX8X modules, while toradex_5.4.y refers to the Upstream Kernel, being the default version in TorizonCore for our iMX6 and iMX7 modules.

So the TorizonCore version that you’ve installed for Apalis iMX8 is using toradex_5.4-2.3.x-imx already, no need to worry about this.

And lastly, your hardware connections seem to be correct. Try changing overlays.txt and see if that solves your issue.

Best regards,
Lucas Akira
