Hello! Thank you for your detailed description of your setup and the troubleshooting you’ve done so far.

Here’s how you can proceed to set up display output on your Aquila AM69 with a DSI to HDMI adapter:

1. Overlay Selection:

  • For the Aquila AM69 with the Toradex DSI to HDMI adapter, the correct device tree overlay to use is verdin-am62_dsi-to-hdmi_overlay.dtbo (not aquila-am69_dsi-to-hdmi_overlay.dtbo) as per the latest documentation:

Please update your /boot/overlays.txt to use:

verdin-am62_dsi-to-hdmi_overlay.dtbo

and then reboot your system.

2. Verifying Display Detection:

  • Boot the system and check if the EDID (Extended Display Identification Data) of your monitor is detected by running:
    find /sys/devices -name "edid"
  • If you see an EDID file, your display connection is recognized at the kernel level.

3. About Weston/Wayland:

  • On Torizon OS, the graphical environment (Wayland/Weston) runs inside a container by default. If it isn’t running, the display output will remain blank even if the hardware is detected.
  • On the Reference Multimedia Image (BSP Linux), a display compositor (like Weston/X11) does not run by default. You need to start your own graphical application or compositor.

Suggested Steps:

  • Try the correct overlay and verify EDID detection first as described above.
  • If using Torizon OS, ensure the “Weston” container is running. You can check running containers with:
    docker ps
  • For BSP Linux, consider starting a graphical application manually for testing, such as running kmscube or installing and running Weston/X11 as needed.

Additional Notes:

  • Ensure the DSI to HDMI adapter is properly and securely connected.
  • Double-check your monitor input settings and cables.

For detailed steps and more troubleshooting on displays:

Please try these steps and update me on your EDID detection and whether the correct overlay resolves your display issue.
