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 can see from your boot logs that you’re experiencing a display issue with your Verdin iMX8M Plus. The key problem is that both HDMI overlays are being applied simultaneously, which is causing conflicts.

The Issue

From your boot logs, I can see both overlays are being applied:

  • Applying Overlay: verdin-imx8mp_hdmi_overlay.dtbo
  • Applying Overlay: verdin-imx8mp_dsi-to-hdmi_overlay.dtbo

This is causing the DSI errors you’re seeing: (1)

imx_sec_dsim_drv 32e60000.mipi_dsi: [drm] ERROR modalias failure on /soc@0/bus@32c00000/mipi_dsi@32e60000/port@1

Solution

You need to ensure only one HDMI overlay is active. For native HDMI on Verdin iMX8M Plus, you should use only the verdin-imx8mp_hdmi_overlay.dtbo overlay. (1)

Step 1: Check Current Overlay Configuration

First, let’s see what overlays are currently enabled:

cat /boot/overlays.txt

Step 2: Correct the Overlay Configuration

Edit the overlays.txt file to include only the native HDMI overlay: (2)

sudo nano /boot/overlays.txt

The file should contain only:

fdt_overlays=verdin-imx8mp_hdmi_overlay.dtbo

Step 3: Alternative Method - U-Boot Environment

If the overlays.txt approach doesn’t work consistently, you can try setting the overlay through U-Boot environment variables. During boot, interrupt U-Boot and run: (2)

setenv skip_fdt_overlays 1
boot

This will disable all overlays temporarily, allowing you to boot and then properly configure the overlay files.

Step 4: Verify and Reboot

After making changes:

sync
sudo reboot

Important Note

According to the documentation, for Verdin family modules, you should disable the DSI-to-HDMI overlay when using the carrier board’s native HDMI interface, as the display pipeline may be routed incorrectly otherwise. (1)

The native HDMI interface overlay verdin-imx8mp_hdmi_overlay.dtbo provides a default resolution of 1920x1080. (1)

Try this approach and let me know if the display output appears correctly after the reboot.
