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 bundles.properties 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

#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

• 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
