Hello!

To integrate your LVDS display with the Verdin AM62, you can follow these steps:

  1. Device Tree Overlay: Use the device tree overlay approach. The pre-built overlay for LVDS displays is verdin-am62_panel-cap-touch-10inch-lvds_overlay.dtbo. You can find more details in the Toradex documentation.

  2. Dual-Channel LVDS Configuration: For dual-channel LVDS, consider the following:

    • It supports resolutions up to 1920x1080 @60fps with a maximum pixel clock of 160MHz. More information is available here.
    • Configure the interface to handle odd pixels in the first channel and even pixels in the second channel.

  3. Display Control Signals:

    • Use PWM_3_DSI for controlling display brightness.
    • Use I2S_2_D_OUT for enabling the display backlight. Further details can be found in the Verdin product family specification.

  4. Capacitive Touch Integration:

    • The touch interface requires a separate cable connection. Ensure the cable is properly oriented, with the blue part facing down on the connector. You can refer to this community discussion for more insights.

  5. Enabling the Display:

    • Add the required overlay to your /boot/overlays.txt file and reboot the system after making changes. Detailed instructions are available in the Toradex documentation.

If you have any specific questions or need further clarification on any of these points, feel free to ask!
