Verdin iMX8M Mini - Dahlia - Capacitive Touch Display 10.1" LVDS - Touch Screen is not working

Hello guys,

I’m trying to use the touch screen function, I’ve already change the touch-atmel-mxt_overlay.dtbo verdin-imx8mm_sn65dsi84-lt170410_overlay.dtbo verdin-imx8mm_sn65dsi84_overlay.dtbo.

The display is showing my application, but the touch screen is not working.

Should I install some driver or use another overlay to make it work ?

Hi @V_D_ALMEIDA,

Did you connect everything properly, as mentioned in the guide below?

Also, can you send us the output from sudo fw_printenv fdtfile ?

Best regards,
Hiago.

Sudo output:

Yes, the image is displaying, as you can see in the photo below:

Hiago,

I’ve performed a double check and found out that the flex cable was miss connected.

After the correction the touch was enabled.

I want to run a virtual keyboard container, does toradex have a container like this ?

Hi @V_D_ALMEIDA,

I’m glad that you solved your issue.

For chromium-based UI, you can enable it by passing the argument --virtual-keyboard. You can check how to do it here: Web Browser / Kiosk Mode with TorizonCore | Toradex Developer Center

Best Regards,
Hiago.
