LSD.JXE

Basics

Location

/ifs/lsd.jxe???

Run script

/mnt/app/eso/hmi/lsd/lsd.sh

Run script variables

export MOUNT_DIR=
export MOUNT_APP_DIR=/mnt/app
export BASE_DIR=$MOUNT_APP_DIR/eso/hmi
export LSD_DIR=$MOUNT_DIR/ifs
export GRAPHICS_DIR=$BASE_DIR/graphics

lsd.sh flags and VMOPTIONS

Some functions and options of the LSD.JXE can be adjusted and passed via a VMOPTION parameter. This will allow to run it in with some debug options, experimental features, bypassing safety check, changing screen resolution, etc.

More information about VMOPTIONS.

LSD.jxe development mode

Warning! In my case developer mode caused screen freeze. I was able to recover the unit.

How to enable dev mode

DEV_ACTIVATED=$BASE_DIR/lsd/development_activated

Enable development mode by creating this empty file:

touch /mnt/app/eso/hmi/lsd/development_activated && sync && sync && sync

How to disable dev mode

rm /mnt/app/eso/hmi/lsd/development_activated && sync && sync && sync

What is dev mode?

If development mode is enabled, it will trigger couple things in LSD.JXE.

• overwrites JAVA_HOME directory path.

if [[ -f $DEV_ACTIVATED ]]; then
 	if [[ -d $BASE_DIR/lsd/jre ]]; then
 		export JAVA_HOME=$BASE_DIR/lsd/jre
 	fi
 fi

* loads <code>bundles.properties</code> file
 if [[ -f $DEV_ACTIVATED ]]; then
   VMOPTIONS="$VMOPTIONS -Dlsd.bundles=$BASE_DIR/lsd/bundles.properties"
 fi

• sets dev_mode variable for hmi logic, sets path to external hmi.zip boot class if it exists

#development mode
 if [[ -f $DEV_ACTIVATED ]]; then
 	echo "######################################"
 	echo "#     DEVELOPER MODE ACTIVE          #"
 	echo "######################################"
 	echo "BASEDIR = $BASE_DIR"
 
     VMOPTIONS="$VMOPTIONS -Ddev_mode=true"
 
 	##
 	## hmi.zip classpath
 	##
 	HMI_ZIP=$BASE_DIR/lsd/hmi.zip
 	if [ -f "$HMI_ZIP" ]; then
 		BOOTCLASSPATH="$BOOTCLASSPATH:$HMI_ZIP"
 	fi
 
 	# use JXE from basedir (eso/hmi) if it exists
 	if [[ -f $BASE_DIR/lsd/lsd.jxe ]]; then
 		LSD_JXE=$BASE_DIR/lsd/lsd.jxe
 	fi
 fi

* outputs diagnostic info
 <nowiki>#Diagnosis output in development mode:
 if [[ -f $DEV_ACTIVATED ]]; then
 	echo "JAVA_HOME=$JAVA_HOME"
 	echo "VMOPTIONS=$VMOPTIONS"
 	echo "BOOTCLASSPATH=$BOOTCLASSPATH (plus lsd.jxe)"
 	echo "LD_LIBRARY_PATH=$LD_LIBRARY_PATH"
fi</nowiki>

• executes this

if [[ -f $DEV_ACTIVATED && -f "$HMI_ZIP" ]]; then
 	# start hmi.zip
 	info "starting j9 with $HMI_ZIP"
 	$J9 $VMOPTIONS -Xbootclasspath:$BOOTCLASSPATH de.dreisoft.lsd.LSD &
 else
 	if [[ -f "$LSD_JXE" ]]; then
 		# start lsd.jxe
 		BOOTCLASSPATH="$BOOTCLASSPATH:$LSD_JXE"
 		info "starting j9 ...."
 		$J9 $VMOPTIONS -Xbootclasspath:$BOOTCLASSPATH -jxe:$LSD_JXE &
 	else
 		echo !!!!!  lsd.jxe not found !!!!!
 	fi
 fi

Tweaks

Google Earth / Satellite View license bypass

Not working. Passing flag will only remove the popup warning about invalid license. Validation is done on server side.

Apple Siri / Google Assistent patch

Not 100% sure, but this might disable the SDS popup about external SDS when using Siri/Assistant. Will try it soon.

VMOPTIONS="$VMOPTIONS -DsdsLogicalPopup=false"

Touchpad input rubberband disable

Not 100% sure, but this might disable inertion of user input from the touchpad (map scrolling, balance/fader setting)

touch /mnt/app/eso/hmi/disableRubberbandCrosshair && sync && sync && sync

Car Menus override

//TODO

More TODOOO

Look for:

flush
deviceModeToString
initAudioFocusManagement

...to find potentially interesting elements of the code.
