Hello
I am having problems when trying to build a custom Yocto image for Apalis IMX6.
The custom image mostly uses Qt5 libs with different libraries. Here is the image files in recipes-images

DESCRIPTION = "Minimal Qt5-enabled image with X11"
LICENSE = "MIT"

ROOTFS_PKGMANAGE_PKGS ?= '${@oe.utils.conditional("ONLINE_PACKAGE_MANAGEMENT", "none", "", "${ROOTFS_PKGMANAGE}", d)}'

I have added the steps needed for adding a splash-screen with the Plymouth tool from this article, but when booting the Apalis board on my 7" touch screen it doesn’t show anything.
I also have a problem where when i add a USB stick I need to manually mount it instead of it mounting automatically. I use udev and have a mount.sh script in the yocto build that looks like this:
#!/bin/sh
#
# Called from udev
#
# Attempt to mount any added block devices and umount any removed devices
LOGFILE="/tmp/mount.sh.log"
exec >> "$LOGFILE" 2>&1
echo
echo "====== $(date) ======"
echo "Running with ACTION=$ACTION, DEVNAME=$DEVNAME, ID_FS_TYPE=$ID_FS_TYPE"
env | grep -E '^(ACTION|DEVNAME|ID_|MAJOR|MINOR)' || true
MOUNT="/bin/mount"
PMOUNT="/usr/bin/pmount"
UMOUNT="/bin/umount"
BLACKLIST="/etc/udev/mount.blacklist"
MOUNTBASE="/media"
# Check if blacklisted
if [ -f "$BLACKLIST" ]; then
while read -r line; do
case "$line" in
""|\#*) continue ;; # Skip comments and empty lines
esac
echo "$DEVNAME" | grep -q "^$line" && {
logger -t udev/mount.sh "$DEVNAME is blacklisted, ignoring"
exit 0
}
done < "$BLACKLIST"
fi
automount() {
name="$(basename "$DEVNAME")"
mount_point="$MOUNTBASE/$name"
[ ! -d "$mount_point" ] && mkdir -p "$mount_point"
case "$ID_FS_TYPE" in

if ! $MOUNT -t auto $OPTIONS "$DEVNAME" "$mount_point"; then
logger -t udev/mount.sh "Mount failed: $DEVNAME -> $mount_point"
rm_dir "$mount_point"
else
logger -t udev/mount.sh "Auto-mount successful: $DEVNAME -> $mount_point"
touch "/tmp/.automount-$(basename "$DEVNAME")"
fi
}
rm_dir() {

[ -d "$dir" ] && [ "$(find "$dir" -type f | wc -l)" -eq 0 ] && rm -r "$dir"

for mnt in $(grep "$DEVNAME" /proc/mounts | awk '{print $2}'); do
$UMOUNT "$mnt"
done
name="$(basename "$DEVNAME")"
[ -e "/tmp/.automount-$name" ] && rm_dir "$MOUNTBASE/$name"
fi
When i mount the stick manually I don’t get no problems.
Generally we used a custom built Toradex image with thud and now I am trying to make it work with scarthgap. I replaced and modified the files that gave me conflicts and the libs installed correctly the only two problems so far that I have found are the splash screen and mount.
Help would be appreciated.
Thank you in advance,
Tarik
