Hello,

It seems you’re encountering an issue where Plymouth is not displaying your custom splash screen on the Verdin iMX8MP module, resulting in a black screen. Here are some steps to help you debug and resolve this issue:

  1. Verify Theme Configuration: Ensure that the theme you want to use is correctly set as the default. You can do this by running:

    plymouth-set-default-theme -l
plymouth-set-default-theme <your-theme-name>
update-initramfs -u

    Replace <your-theme-name> with the name of your desired theme.

  2. Enable Verbose Logging: Although Plymouth doesn’t log extensively by default, you can enable verbose logging to gather more information. Add plymouth.debug=1 to your kernel command line parameters to increase verbosity.

  3. Test Plymouth Manually: After booting, try running Plymouth manually to see if it displays correctly:

    plymouthd --debug
plymouth --show-splash

    This can help identify if the issue is with the boot process or Plymouth itself.

  4. Check Display Configuration: Ensure that the display settings are correctly configured for your HDMI output. Verify that the correct DRM driver is loaded and that the display is initialized properly before Plymouth starts.

  5. Verify Theme Files: Check that all necessary files for your theme are present and correctly formatted. Missing or corrupt files can cause Plymouth to fail to display the splash screen.

  6. Update Kernel and Initramfs: Ensure that your kernel and initramfs are correctly updated with the Plymouth configuration. Sometimes, changes might not be applied if the initramfs is not rebuilt properly.

By following these steps, you should be able to identify the cause of the black screen and ensure that your custom splash screen is displayed correctly. If the issue persists, consider testing with a different theme or checking for any specific compatibility issues with the Verdin iMX8MP module.
