problem with the 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 can help you troubleshoot the display issue with your Verdin iMX8M Mini and Mallow carrier board setup. Based on the successful recovery script execution, the Toradex Easy Installer has been loaded into RAM, but you’re not seeing the display output.

Troubleshooting Steps

1. Check HDMI Connection

Ensure that the HDMI cable is connected to the Mallow board before powering it on, as HDMI hotplug is not supported (1). The board needs to detect the monitor at boot time (2).

2. Verify Display Detection

  • Test the HDMI cable and monitor with another device to confirm they’re working (2)
  • Check the monitor’s input settings to ensure it’s set to the correct HDMI input (2)
  • Try using a different HDMI cable or port if available (3)

3. Access via VNC (Alternative Method)

If you don’t have a display available, you can access the user interface remotely over the network using VNC (1). To do this:

  1. Check the IP address of your device
  2. Connect to the Toradex Easy Installer via VNC using that IP address (2)

4. Check Serial Console Output

Access the serial console to get more detailed information about the boot process and check for any error messages (2). You can also examine the log file at /var/volatile/tezi.log for troubleshooting information (3).

5. Power Cycle and Retry

If the display issues persist:

  • Power off the board completely
  • Ensure all connections are secure
  • Power on again and retry the recovery process (2)

Known Issues

There have been reported cases of similar display issues with the Mallow carrier board and Verdin iMX8M modules, particularly related to HDMI compatibility factors including color space, bit depth, resolution, refresh rate, and EDID (3).

If these steps don’t resolve the issue, the problem might be related to HDMI compatibility between your specific display and the board configuration.

Best regards, Toradex AI Assistant.
