Hi Community,

I’m trying add device tree overlay of Capacitive Touch Display 10.1" LVDS to Toradex Apalis iMX8 through the steps provided here (First approch). I’m using Ixora V1.2A board.
But after executing the last command, i get the follwing error.

torizoncore-builder dto deploy --remote-host 192.168.2.110 --remote-username torizon --remote-password tata1234 --force --reboot device-trees/overlays/apalis-imx8_lvds_overlay.dts

Hi @hareendran-tl ,

This error with the dto deploy command is a known issue we’re currently working on. In the meantime I’d recommend instead following Approach 1 for development and production i.e. using the build command as instructed here: Device Tree Overlays on Torizon | Toradex Developer Center.

With this you can specify which overlays to add using the tcbuild.yaml file and output a custom image in a folder.

After this you can deploy it directly via SSH using the following commands:

torizoncore-builder images unpack <folder that has the built image>
torizoncore-builder deploy --remote-host <your-IP> --remote-username torizon --remote-password <your-password> --reboot

See if this works for you.

Best regards,

Hi @lucas_a.tx ,

I have tried the approch you mentioned and all the steps are completed successsfully without an error, and the OSTree commit hash is also same, so new custom image of TorizonCore is active on the device.

Even though, the display is still not working. It just powering on and reamins in standby condition.
I used the below tcbuild.yaml file

input:
  easy-installer:
    local: torizon-core-docker-apalis-imx8-Tezi_5.7.0+build.17.tar

customization:
  device-tree:
    include-dirs:
      - device-trees/include/
    custom: device-trees/dts-arm64/imx8qm-apalis-v1.1-ixora-v1.2.dts
    overlays:
      add:
        - device-trees/overlays/apalis-imx8_lvds_overlay.dts
output:
  easy-installer:
    local: torizon-core-docker-apalis-imx8-Tezi_5.7.0.CUSTOM

Hi @hareendran-tl ,

Regarding the image customization using torizoncore-builder build you seem to do everything correctly.

But in order for the Capacitive Touch Display 10.1" LVDS to work you need to add more overlays in your image, as specified in this table: Device Tree Overlays on Torizon | Toradex Developer Center.

For your case:

  • Apalis iMX8
  • Ixora V1.2
  • Kernel toradex_5.4-2.3.x-imx
    (Downstream from NXP, the default kernel version in our TorizonCore releases for ARM64 devices)

You have to add the following overlays in this order:

input:
  easy-installer:
    local: torizon-core-docker-apalis-imx8-Tezi_5.7.0+build.17.tar

customization:
  device-tree:
    include-dirs:
      - device-trees/include/
    custom: device-trees/dts-arm64/imx8qm-apalis-v1.1-ixora-v1.2.dts
    overlays:
      add:
        - device-trees/overlays/apalis-imx8_lvds_overlay.dts
        - device-trees/overlays/apalis-imx8_atmel-mxt_overlay.dts
        - device-trees/overlays/display-lt170410_overlay.dts
output:
  easy-installer:
    local: torizon-core-docker-apalis-imx8-Tezi_5.7.0.CUSTOM

With this you should see the Torizon logo as a splash screen on the display when booting the image.

Let me know if this works.

Best regards,

Hi @lucas_a.tx ,

Thanks for your support.
The updated tcbuild.yaml file helps me to enable the display.

By the way, is there a way to enable virtual keyboard? I’m runnig a qt application following this reference.

Hi @hareendran-tl ,

Glad that solved your display issue!

About enabling a virtual keyboard, you can check this topic here if you’re using Weston: Virtual keyboard in Weston?

You can also check the Qt virtual keyboard package as referenced in the article you’ve linked: Qt C++ Application Development on Torizon Using Visual Studio Code | Toradex Developer Center
