Hello there,

I’m sorry to hear about the difficulties you’re experiencing with your display setup. Let’s go through some steps to help you resolve this issue:

1. Verify Connections:

   • Double-check that all physical connections are secure and correct. Ensure that the cables and connectors for HDMI, LVDS, and MIPI DSI are properly seated and connected to the appropriate ports.

2. Check Device Tree Overlays:

   • The overlays you mentioned, verdin-am62_dsi-to-hdmi_overlay.dtbo and verdin-am62_spidev_overlay.dtbo, might not be sufficient for your display setup. You may need a specific overlay for the LVDS or MIPI DSI interface, depending on your display’s requirements.
   • You can modify the overlays by editing the uEnv.txt file in the boot partition of your TorizonCore installation to ensure the correct overlay for your display interface is enabled.

3. Configure Display Settings:

   • Ensure that the display settings in TorizonCore match your display’s specifications, such as resolution and refresh rate. This can often be adjusted through TorizonCore settings or by modifying the device tree.

4. Test with a Known Good Display:

   • If possible, try your setup with a different display to rule out any hardware issues with the current display.

5. Review Logs:

   • Check the system logs for any errors or warnings related to the display. Use commands like dmesg or journalctl to view these logs and identify any potential issues.

6. Consult Documentation:

   • Refer to the Toradex documentation for the Verdin AM62 and your specific display to ensure all requirements and configurations are met.

By following these steps, you should be able to identify and resolve the issue with your display. I hope this helps, and I wish you the best of luck in getting your display up and running!

Best regards,
Toradex AI Assistant
