I am currently working on a project involving both Yocto Project and an i.MX-based Toradex board. This is my first time working with both Yocto and the i.MX platform, and I’m encountering an issue that I believe you might be able to help me with.
The problem I am facing relates to the boot animation using Plymouth. Specifically:
I have configured Plymouth to display a boot splash screen during system initialization.
However, the splash screen behavior is inconsistent; it either doesn’t appear as expected or terminates prematurely.
I would appreciate your expertise in diagnosing and resolving this issue.
Thank you very much for your time and support.

Hello,
Thank you for reaching out with your question about the Plymouth boot animation on your i.MX-based Toradex board. I understand how challenging it can be to work with new platforms and tools like Yocto and Plymouth. Let’s go through some steps that might help resolve the issue you’re experiencing with the splash screen.
Verify DRM Modesetting: Plymouth requires DRM modesetting drivers for proper operation. Please ensure that your board’s kernel is configured with the necessary DRM drivers. You can check the kernel configuration or system logs to confirm that DRM is enabled and functioning correctly.
Check Initramfs Configuration: Since Plymouth starts from the initramfs, make sure that your initramfs is correctly configured to include Plymouth and its dependencies. Verify that the initramfs is being generated and deployed correctly during the build process.
Plymouth Theme and Configuration: Ensure that the Plymouth theme you are using is compatible with your display settings. Check the Plymouth configuration files, usually located in /etc/plymouth/, to ensure the correct theme is set and that any custom settings are properly configured.
Hardware Compatibility: Confirm that your display hardware is supported. Some Toradex boards may have limitations with specific display outputs, such as HDMI. Ensure that your display setup is compatible with the board’s capabilities.
Log Analysis: Check system logs for any errors or warnings related to Plymouth. Logs can provide insights into why the splash screen might not be displaying as expected. Use commands like dmesg or check /var/log/ for relevant log files.
Test with a Minimal Configuration: Temporarily simplify your setup by using a basic Plymouth theme and minimal initramfs configuration to isolate the issue. This can help determine if the problem is with the theme or a more fundamental configuration issue.
By following these steps, you should be able to diagnose and resolve the inconsistencies with the Plymouth splash screen on your Toradex board. I hope this helps, and I wish you success with your project.
