psplash image does not appear (yocto & qemu) - linux

Question

i'm trying to make my first steps with yocto.
While using psplash i can see the yocto-splashscreen only while shutting down the system. Not while the system is booting up.
For this i'm using a Ubuntu 18.10 in a Virtual Box (oracle).
I build the image with this commans:
~$ sudo apt-get install git python chrpath g++ gawk gcc make texinfo
~$ git clone -b sumo git://git.yoctoproject.org/poky
~$ cd poky/
~/poky$ source oe-init-build-env
~/poky/build$ nano /conf/local.conf
insert at the end of file:
BB_NUMBER_THREADS = “8”
PARALLEL_MAKE = “-j 4”
IMAGE_INSTALL_append = “ psplash”
INHERIT_remove = “uninative”
build with:
~/poky/build$ bitbake core-image-minimal
run the image with:
runqemu qemux86
While booting up i noticed the following two messages:
framebuffer /dev/fb0 not detected
Boot splashscreen disabled
I found this question: yocto splash screen not appearing
I already try to add IMAGE_INSTALL_append = " psplash" in the local.conf but no effect.
Do you have some ideas?

Answer 1

I just had the same problem. Apparently yocto would create a file /etc/rc.d/S00psplash.sh . S00 means this is executed right at the beginning of the boot process, before the required graphics drivers are loaded. I changed it to S40 and it worked. Not sure yet how to fix this inside yocto. You might also need to add to your local.conf:
DISTRO_FEATURES_append = " directfb" # (not sure whether this is really required)
and
IMAGE_FEATURES_append = " splash" # (this might already be enabled for your image)
If it does not work please report back
Best regards ~

Screenshot
Here you can see the described boot-sequence
framebuffer /dev/fb0 not detected
Boot splashscreen disabled
comes from the psplash-init file
#!/bin/sh
### BEGIN INIT INFO
# Provides: psplash
# Required-Start:
# Required-Stop:
# Default-Start: S
# Default-Stop:
### END INIT INFO
echo "########################################################"
if [ ! -e /dev/fb0 ]; then
echo "Framebuffer /dev/fb0 not detected"
echo "Boot splashscreen disabled 1"
exit 0;
fi
read CMDLINE < /proc/cmdline
for x in $CMDLINE; do
case $x in
psplash=false)
echo "Boot splashscreen disabled 2"
exit 0;
;;
esac
done
export TMPDIR=/mnt/.psplash
mount tmpfs -t tmpfs $TMPDIR -o,size=40k
rotation=0
if [ -e /etc/rotation ]; then
read rotation < /etc/rotation
fi
/usr/bin/psplash --angle $rotation &
So the try to show the splashscreen (lines 6-7 in screenshot) occures before the framebuffer is loaded (from line 13 ...)
Is this right?
I'm wondering about the message "Please wait: booting...."
Do we talk about different bootsteps? (like bootloader-boot and linux-boot)
