Regarding splash screen image not shown using plymouth

Devireddy · February 27, 2025, 8:34am

Hello,
my requirement is boot animation using plymouth .
i already have plymouth in openembeeded layer so i add the plymouth.bbappend file in my custom layer
i added the .plymouth file and image under files directory

plymouth_%.bbappend
FILESEXTRAPATHS:prepend := “${THISDIR}/files:”
SRC_URI:append = "
file://spinner.plymouth
file://rasppi_fixed_converted.png
"
do_install:append() {
install -d ${D}${datadir}/plymouth/themes/spinner
install -m 0644 ${WORKDIR}/spinner.plymouth ${D}${datadir}/plymouth/themes/spinner/
install -m 0644 ${WORKDIR}/rasppi_fixed_converted.png ${D}${datadir}/plymouth/themes/spinner/
# Set default theme
#echo “spinner” > ${D}${sysconfdir}/plymouth/plymouthd.conf
install -d ${D}${sysconfdir}/plymouth
echo “[Daemon]\nTheme=spinner” > ${D}${sysconfdir}/plymouth/plymouthd.conf
}
DEPENDS += “libpng”
EXTRA_OECONF += “–enable-png”
PLYMOUTH_THEMES = " spinner"

Set the default theme to “spinner”

PACKAGES += “plymouth-theme-spinner”
#FILES:plymouth-theme-spinner += “${datadir}/plymouth/themes/spinner/”
FILES:plymouth-theme-spinner += “${datadir}/plymouth/themes/spinner/ ${sysconfdir}/plymouth/plymouthd.conf”
PACKAGES += “plymouth-utils”
FILES:${PN}-utils = “${bindir}/plymouth-set-default-theme ${bindir}/plymouth”

Hi, I’m the Toradex AI Assistant. The Toradex Support team will follow up with you shortly!

Did you like my answer?

Hello,

It seems you’re working on implementing a boot animation using Plymouth on a custom Yocto build for your Toradex device. You’ve made several configurations, but the splash screen isn’t displaying as expected during boot. Let’s go through some steps to troubleshoot and resolve this issue:

Verify File Paths and Permissions: Double-check that the paths specified in your .bbappend file are correct and that the files are being installed in the expected directories. Ensure the image files have the correct permissions to be readable by Plymouth.
Check Plymouth Configuration: Confirm that the plymouthd.conf file is correctly set up to use your custom theme. The theme name in the configuration should match the directory name where your theme files are located.
DRM and Framebuffer Support: Plymouth relies on DRM for graphical output. Ensure your kernel and device tree support DRM and framebuffer. Check the kernel configuration for DRM support and ensure the necessary modules are loaded.
Enable Plymouth Debugging: Add plymouth.debug to the kernel command line to enable detailed logging. This can help identify where the process might be failing.
Review Boot Logs: Examine the system logs (dmesg and journal logs) for any errors related to Plymouth or framebuffer initialization. These logs can provide clues if there are issues with the graphics driver or Plymouth itself.
Test Plymouth Manually: Since running plymouthd && plymouth --show-splash works manually, the issue might be with the automatic start during boot. Ensure Plymouth is correctly integrated into the boot process by checking the init system (systemd) configuration.

By following these steps, you should be able to identify and resolve the issue with your Plymouth splash screen not displaying during boot. If the problem persists, consider simplifying the setup to a minimal configuration and gradually adding complexity to isolate the cause.

Best regards,
Toradex AI Assistant

Hi @Devireddy ,
Are you still facing this issue?

Devireddy · March 3, 2025, 4:23am

yes still i am facing same issue prem

prem0919 · March 3, 2025, 6:16am

Hi @Devireddy ,
Have you added this patch?

github.com

toradex/meta-toradex-torizon/blob/kirkstone-6.x.y/recipes-core/plymouth/files/0001-disable-boot-splash-later.patch

From ef09d07359e5a2dca1dd3a723c31c53d601492cf Mon Sep 17 00:00:00 2001
From: Stefan Agner <stefan.agner@toradex.com>
Date: Tue, 4 Feb 2020 16:23:46 +0100
Subject: [PATCH] disable boot splash later

Currently we have one big target (multi-user.target) for lots of
services. This does not allow to order the plymouth-quit.service to get
started at the very end. Work around by explicitly order after
docker.service.

Add the patch which i have shared and test the image.

Devireddy · March 3, 2025, 6:44am

i will do that prem

Devireddy · March 3, 2025, 6:57am

I have one doubt prem, if we are not using docker then also we need to use this patch

prem0919 · March 3, 2025, 7:19am

@Devireddy ,
Yes, add the patch and verify plymouth service is started or not.

Devireddy · March 3, 2025, 8:28am

i added that patch still issue is same
when i run plymouth --show-splash it is showing screen with loading symbol

prem0919 · March 3, 2025, 8:33am

Check the service is loaded or not

Devireddy · March 3, 2025, 8:35am

Service is loaded

prem0919 · March 3, 2025, 8:40am

change the logo name to torizonlogo-white.png
and change the
do_install:append () {
install -m 0644 ${WORKDIR}/torizonlogo-white.png ${D}${datadir}/plymouth/themes/spinner/watermark.png
install -m 0644 ${WORKDIR}/spinner.plymouth ${D}${datadir}/plymouth/themes/spinner/spinner.plymouth
}

Devireddy · March 3, 2025, 9:19am

changed still not working

Hello prem ,do you got any conflict between plymouth and weston

prem0919 · March 3, 2025, 3:41pm

Hi @Devireddy,
I have implemented this in verdin-imx8mp platform.

Devireddy · March 3, 2025, 3:44pm

Okay. Can you the procedure you implemented in verdin-imx8mp platform.
When i implemented in raspberry-pi after booting i am getting it is stuck in execu systemcall
