Java support is here, let's go start. My tv is F8000
Download the latest
http://www.oracle.com/technetwork/java/ ... index.html for SoftFP ABI on your pc.
Make sure that you have installed java there with exported JAVA_HOME variable
My system is OS X based but the procedure for Linux is the same. Windows procedure it may be the same, but check the documentation.
You can create your JRE configuration to be minimal or full
Navigate to extracted java package and execute.
Minimal:
Code: Select all
./bin/jrecreate.sh --dest jre8 -p compact1
Full
Code: Select all
./bin/jrecreate.sh --dest jre8 --vm all
Compress the output directory
Transfer jre8.zip to your tv /mtd_rwcommon directory.
Extract it's content.
Modify /mnt/etc/rc.sysinit file as following
Java executables path should be added to system path
Code: Select all
export PATH="$DISTROOT/sbin:$DISTROOT/bin:$DISTROOT/usr/bin:$DISTROOT/usr/sbin:$SYSROOT/sbin:$SYSROOT/bin:$SYSROOT/usr/bin:$SYSROOT/usr/sbin:/mtd_rwcommon/jre8/bin/:$PATH"
Java home sys variable should be added into the same file
Code: Select all
export JAVA_HOME="/mtd_rwcommon/jre8/"
Restart the TV and test your java installation
minimal configuration
Code: Select all
root@tv:/mnt # java -version
java version "1.8.0_71"
Java(TM) SE Embedded Runtime Environment (build 1.8.0_71-b15, profile compact1, headless)
Java HotSpot(TM) Embedded Minimal VM (build 25.71-b15, mixed mode)
full jre
Code: Select all
root@tv:/mtd_rwcommon $ java -version
java version "1.8.0_71"
Java(TM) SE Embedded Runtime Environment (build 1.8.0_71-b15, headless)
Java HotSpot(TM) Embedded Client VM (build 25.71-b15, mixed mode)

Great work
But instead of /mtd_rwcommon/ I would suggest putting on USB (to much data in /mtd_rwcommon CAN cause a brick
)

Good point. I have more than 1GB free there, is save to leave it there or it will be better to be on my ext drive?

Might be good but no warranty
I had about 250MiB of free space and ALMOST bricked TV

Yes I knew the solution and think the best place for the command it should be the same rc.sysinit or you will suggest som different init script?
