Hello,
I tried to run Riverdi 5" RVT50HQLNWCA0 display on Mallow Board
I completed all the connections do one channel using wiring with plug to X12 connector and adapter boards to ZIF connector. I have running overlane verdin-am62_panel-cap-touch-10inch-lvds_overlay.dts but I can see nothiong on the display. When examin by osciloscop there is only clock suignal and no other LVDS singnals.

Hello Sylwester,
Thank you for your detailed description.
The Mallow carrier board officially supports a limited set of displays:
(see the list of compatible displays).
The device tree overlay you mentioned, verdin-am62_panel-cap-touch-10inch-lvds_overlay.dts, is designed for the 10.1" LVDS display. When using it with a different display such as the Riverdi 5", the display timings and configurations (such as resolution, sync polarities, and clock settings) will not match what your 5" panel expects. This is a likely reason why you see no image and only a clock signal on the LVDS lines.
General Guidance:
Display Timings: You need to provide display timings that match your Riverdi 5" panel in a device tree overlay. These include pixel clock, resolution, horizontal and vertical sync lengths, and porch values.
LVDS Channel Mapping: Ensure the LVDS channels are mapped as required by your display and the adapter board connections.
Backlight & Power: Make sure the display is powered correctly and the backlight is enabled.
Touch: If you use the touch interface, ensure it is correctly configured, but the video signal must work first.
Since the Mallow board is not officially validated for the Riverdi 5" display, you will need to customize a device tree overlay for your display. You can refer to First Steps with Capacitive Touch Display 10.1 Inch LVDS for general LVDS display setup instructions, but you must adapt the timings for your 5" panel’s datasheet specifications.
If you wish, I can guide you through creating a custom overlay. Please provide the exact display resolution and pixel clock/timing requirements from your Riverdi 5" panel’s datasheet, and I’ll outline the necessary changes.
Best regards,
Toradex AI Assistant.
Hi @silvo
ToradexAI is correct.
Currently, there is no “out-of-the-box” overlay for this display.
You need to modify the overlay for your specific display.
You can check the " Configure Other Displays with Torizon" section for high-level steps to do this.
If you need help integrating a custom display into your solution, we recommend reaching out to our partner network.

Dear Alan,
We successfully launched the 5" Riverdi RVT50HQLNWCA0 display using the 10" Overlane verdin-am62_panel-cap-touch-10inch-lvds_overlay.dts, modifying the resolution parameters for the 5" 800x480 display, as well as other settings such as timing, pixel clock, sync, and others according to the manufacturer’s specifications. We also managed to get the touch panel working. Previously, there were issues with the display connection cables — it turned out there was a break in the connection, which is why nothing was visible.
Best regards
Sylwester
