Hi, we use the SMARC eval board with a IMX95 SMARC SoC. We connected a Panel Ampire AM1280800 on LVDS connector. Now I would like to develop the device tree overlay file. I saw there is a file “toradex-smarc-imx95_panel-cap-touch-10inch-dsi_overlay.dtbo“. But I can’t find the source file .dts for that. Where can I find it?
Actually I loaded this file and a self written on too, but either does give out a display.
Hi, I’m the Toradex AI Assistant.
I might make mistakes or occasionally get you wrong. Our support team will step in if needed.
I’d be glad to help! To provide you with the most accurate guidance for your SMARC iMX95 setup with the Ampire AM1280800 LVDS panel, could you let me know which OS and version you are using? You can use the tdx-info command to get detailed information about your system - more details at this link.
For finding the device tree source files (.dts), you can access them through the Toradex Device Tree Overlays repository on Github (1)(2). This repository contains the source files for all the pre-built overlays provided by Toradex.
According to the documentation, for SMARC iMX95 (starting from version 7.3.0), the available display overlays include (1):
toradex-smarc-imx95_dsi-to-hdmi_overlay.dtbotoradex-smarc-imx95_panel-cap-touch-10inch-dsi_overlay.dtbotoradex-smarc-imx95_panel-cap-touch-10inch-lvds_overlay.dtbotoradex-smarc-imx95_panel-lvds-dual-channel-1080p_overlay.dtbotoradex-smarc-imx95_panel-edp-142mhz_overlay.dtboFor your Ampire AM1280800 LVDS panel, you’ll likely want to reference the LVDS overlays as a starting point. The toradex-smarc-imx95_panel-cap-touch-10inch-lvds_overlay.dtbo would be the closest match for an LVDS interface (1).
Once you specify your OS version, I can provide more targeted guidance on configuring your custom overlay for the Ampire panel.
Best regards, Toradex AI Assistant.

What do I have to do? Only load the file toradex-smarc-imx95_panel-cap-touch-10inch-lvds_overlay.dtbo ? Or are there other things to do? Do I have to disable the HMDI port?

For SMARC iMX95, the available LVDS overlay is toradex-smarc-imx95_panel-cap-touch-10inch-lvds_overlay.dtbo (1). However, this overlay is specifically designed for Toradex’s Capacitive Touch Display 10.1" LVDS and may not work directly with your Ampire AM1280800 panel.
According to the documentation, SMARC iMX95 has pre-enabled SPIDEV overlays by default (1):
toradex-smarc-imx95_spi0-cs0_spidev_overlay.dtbotoradex-smarc-imx95_spi0-cs1_spidev_overlay.dtbotoradex-smarc-imx95_spi1-cs0_spidev_overlay.dtbotoradex-smarc-imx95_spi1-cs1_spidev_overlay.dtboThe documentation indicates that for SMARC iMX95, native HDMI is “Not supported” (2)(1). The available display options are:
Since your Ampire AM1280800 panel has different specifications than the standard Toradex displays, you’ll likely need to create a custom overlay with the correct timing parameters for your specific panel.
Once you provide your OS version information, I can give you more specific guidance on how to configure the overlay for your Ampire panel and the proper steps to load it.

Hi @inetronic!
I recommend using the toradex-smarc-imx95_panel-cap-touch-10inch-lvds_overlay.dts as a starting point and then making the modifications for your display.
While I personally prefer to disable all unused interfaces and overlays when creating a new device tree overlay, it is not mandatory to disable the HDMI port.
Best regards.
