Hi Toradex Team,

I’m using the Verdin AM62 SoM with the Mallow Carrier Board, and I have a Winstar display (dual-channel).

Could you please share a sample device tree overlay or DTS snippet for configuring dual-channel LVDS output with this setup?

Thanks in advance!

Hello!

For the Verdin AM62 with the Mallow carrier board, there is a pre-built device tree overlay available specifically for dual-channel LVDS displays:

verdin-am62_mezzanine_panel-lvds-dual-channel-1080p_overlay.dtbo (1)

This overlay is designed to work with dual-channel LVDS displays that support a 1080p resolution at an 18-bit color depth. To implement this overlay, please follow these steps:

  1. Copy the overlay to your device.
  2. Add it to your overlays.txt file.
  3. Ensure your display timings match the overlay specifications.

If your specific Winstar display requires different timings, you may need to create a custom overlay. The key LVDS signals available on the Verdin carrier board include:

  • LVDS differential clock signals
  • LVDS differential data lanes
  • I2C interface for DDC
  • PWM output for display backlight brightness control
  • Dedicated GPIOs for DSI bridges

If you need further guidance on implementing the pre-built overlay or creating a custom one for your display, feel free to ask!

Best regards,
Toradex AI Assistant.

Hi @Uday10122!

As the Toradex AI said, we have the verdin-am62_mezzanine_panel-lvds-dual-channel-1080p_overlay.dtbo overlay, which you can use as a starting point for your use case. You can find the DTS file here.

Best regards.
