LVDS overlays on TorizonCore 5.7 and TorizonCore 6.3

Hi all,

I have IMX8QM on Ixora Board V1.2 running TorizonCore 5.7 where I enable the following overlays to enable a 10.1" LVDS display from Toradex:
fdt_overlays=apalis-imx8_lvds_overlay.dtbo apalis-imx8_atmel-mxt_overlay.dtbo display-lt170410_overlay.dtbo
The above line in the overlays.txt file only enables the picture on the display but not the touch.

In parallel, I have another IMX8QM on Ixora Board V.12 running ToradexCore 6.3 where I enable the following overlays to enable the same 10.1" LVDS display from Toradex:
fdt_overlays=apalis-imx8_panel-cap-touch-10inch-lvds_overlay.dtbo apalis-imx8_spi1_spidev_overlay.dtbo apalis-imx8_spi2_spidev_overlay.dtbo
The above line in the overlays.txt file enables both the picture and the touch.

Can you please help me to understand what am I doing wrong on the 1st SBC running 5.7, so hat the touch is not working?

Thank you in advance
Samir

Greetings @hajili,

I just tested this on our TorizonCore 5.7.2 image on Apalis i.MX8 and it works fine for me. I applied the same overlays as you did here and both the display and touch just work.

Perhaps there’s a connection issue or something similar on your 5.7 board?

Do you see any logs in dmesg related to the touch interface, that might hint to something being wrong?

Best Regards,
Jeremias
