Hello All,
I am using Yocto with Toradex Apalis Ixora Carrier Board. I am using the tdx-reference-multimedia-image.
My board is an Apalis IMX8 QM with an ixora 1.2 carrier board.
I Wanna have dual screen HDMI and LVDS(touch screen) together.
I have tried HDMI, and LVDS seperately,it worked but they didnt work together.
We just want to have dual screen LVDS and HDMI!!
Can you explain Whats solution?
Thank you in advance,

Hello @hhami

I hope you are doing well.
If you want to enable both HDMI and LVDS(touch screen) together, the device tree overlays for both these have to be enabled in /boot/overlays.txt for apalis imx8. You can find the list of overlays here: Device Tree Overlays (Linux) | Toradex Developer Center

In my setup to test your use case, I added the following overlays into my /boot/overlays.txt file:
fdt_overlays=apalis-imx8_hdmi_overlay.dtbo apalis-imx8_lvds_overlay.dtbo display-lt170410_overlay.dtbo apalis-imx8_atmel-mxt_overlay.dtbo

Please don’t forget to reboot your module after you have edited the overlays file. Let me know if that solves your issue.

Thanks and regards,
Rudhi Nair
