SamyGO Extensions Pack

What are "SamyGO Extensions"

"SamyGO Extensions" enhance your tv's functionality without patching or modify the firmware!

• Access your network shares and network-storage devices as pseudo usb-devices (it is possible to seek and ff in this files + more media container are supported)
• Enables ssh access to your tv (not telnet! as client you can use putty)
• Additional tools for advanced users like ssh, mksquashfs and checksum-calculator (for sure change from version to version)

Where can you find "SamyGO Extensions"

the released version:

http://download.samygo.tv/

latest beta:

http://linux.zsolttech.com/Samsung/

in samygo openembedded svn

you can get it:

svn co https://samygo.svn.sourceforge.net/svnroot/samygo/oe/branches/branch-0-0-1 SamyGO-Extensions
cd SamyGO-Extensions

edit the makefile to fit the target machine, and start the build.

make -f Makefile-SELP-SamyGO gallery

if the build is ready you can find compiled binaries/kernel modules etc. under

build/tmp/rootfs/

and a "ready to use" zipfile in

build/tmp/deploy/images/

Can you brick your tv with this extensions

answer is simple:

no, but it can kill your cat, burn your house and make horny things with your girlfriend! in worst case your tv shut down and power on again.

except you make changes in the scripts and you didn't know what you done

if you change any of the scripts you also loose the "arris warranty" ;-)

if you need assistance for your own scripts you can ask in:

http://forum.samygo.tv/viewforum.php?f=4

but ask before you bricked your tv!

Is this stuff compatible with your tv

generaly binaries and kernel modules are for ARM architecture (for most devices you can use T-CHU7DEUC based package)

look at the samsung site, download and extract the firmware for your tv and

check the resulting directory name:

• T-PRLAUS -> binaries may work, kernel modules rather not
• T-AMBAUSC -> binaries may work, kernel modules may also
• T-SPHAUSC, T-RBYAUSC -> binaries yes, kernel modules rather not (you can find some precompiled modules in the download section: pickup right one)
• T-CHE7AUSC, T-CHE6AUSC, T-CHE7AUSC, T-CHU7DEUC, T-CHL7DEUC -> binaries yes, kernel modules yes (pls. search in forum, i made all tests on UExxB7020 => T-CHU7DEUC)
• T-CHUCIPDEUC -> binaries may work, kernel modules may also
• T-CHLCIPDEUC -> binaries yes, kernel modules yes (posted by user sondeu)
• T-CHL5DAUC -> binaries may work, kernel modules may also, but first enable network for your device
• T-AMBDFR -> binaries not, kernel modules also not (Renesas SH not ARM)
• T-RBYDEU -> binaries not, kernel modules also not (Renesas SH not ARM)
• T-TDT5DEUC -> binaries not, kernel modules also not (binaries MIPS-II but kernel modules MIPS-32)
• T-MSX5DEUC -> binaries not, kernel modules also not (MIPS-32)
• T-VAL* -> binaries may work, kernel modules rather not (ARMv7) (defined as T-CSERIES.. in OE barnch)

your tv have to support games in "content library", "usb movie" and for c-series Internet@TV, pls. consult the manual (or use the commandline start method)

• if you use the samygo openembedded svn, this limitations to tv types are never true. you can recompile the whole stuff for your tv. feel free to test it and don't fear the penguin.
• precompiled packages

General usage

on C-Series from Widget

=> See also: How to get root access on a C series TV

extract the zip file to usb-pen

mv SamyGO directory into the root-directory of the usb-pen

enable run.sh script method for your tv

add the line

/dtv/usb/sda1/SamyGO/rcSGO >/dev/null 2>&1 &

to the run.sh script or change usb_hotplug.sh script to call

$MOUNTBASEDIR/$PARTITION/SamyGO/rcSGO $MOUNTBASEDIR/$PARTITION/SamyGO >/dev/null 2>&1 &

instead of

sh -x $MOUNTBASEDIR/$PARTITION/run.sh $MOUNTBASEDIR/$PARTITION

on B-Series from Content Library

extract the zip file to usb-pen

mv SamyGO directory into the root-directory of the usb-pen

on some models (like T-SPHAUSC based) you have to create a directory SEC_GAME on your usb-pen and move the SamyGO directory into this dir, not into the root-directory

you have also rename the SamyGOE.so to libSamyGO.so an you also need an extra configuration file SamyGO.dat

more instructions at

connect usb-pen to tv

wait few seconds for automatic usb connection menu on tv

select "content library"

go to usb -> games, and select "SamyGO Extensions" (with "ok" button on remote-control)

after the colored screen goes away, up to ~27 sec. (this is true up to SamyGO All Extensions v0.04, later versions will have some kind of control-panel)

exit from "content library" and go to "media play" ("media.p" button on remote-control)

select source (red button on remote-control)

depends on your network services you can see new usb-sources (this are "faked" devices)

• "UPNP Server"
• "Samba Server"
• "NFS Server"

select one of them, pick what you want to see (pictures, music or video) than you should see your server(s), enjoy your media(s)

on any model where you can start a script

Start extensions from patched firmware / from other script

If you have patched your firmware with SamyGO Firmware Patcher than you can start the extensions at boot time, simply add the line

<somedir>/SamyGO/rcSGO &

to the script

/mtd_rwarea/SamyGO.sh

before the

exit

command.

<somedir> differs how you are using the extensions (usb, tv's internal flash memory, nested into a children/game content)

some possible locations:

/dtv/usb/sda1/SamyGO/rcSGO
/dtv/usb/sda1/SEC_GAME/MagicCube/SamyGO/rcSGO
/dtv/usb/sda1/SEC_GAME/SamyGO/rcSGO
/dtv/usb/sda4/SamyGO-All-Extensions/mtd_tlib/SamyGO/rcSGO
/dtv/usb/sda/SEC_GAME/DBowling/SamyGO/rcSGO
/dtv/usb/sda/SEC_GAME/WiseStar/SamyGO/rcSGO
/mtd_tlib/GGame/SamyGO/rcSGO

don't copy the extensions (SamyGO directory) to /mtd_rwarea!!!

Copy extensions to tv's flash memory

on some models it is possible to copy contents to tv's memory in the

same way you can copy "SamyGO All Extensions" pack to flash

yellow button ..., pls. look into the manual or search in forum

If you can't copy "SamyGO All Extensions" via TV you can do it with a telnet or ssh connection

cp -a /dtv/usb/sda1/SamyGO /mtd_tlib/GGame/

or you can try to enable the write function to content library

instructions in forum

then you can start the extensions via the "content library" -> "Games" (if your tv supports this function)

Components, Design and Structure

1. StarterLib

   libSamyGO.so -> starts the extensions from "content library"

2. CoreScript

   rcSGO -> 1. of main start scripts, it try to "find" the extension and creates a working enviroment

   etc/rc.sysinit -> 2. of main scripts, it handles the start of the services (init scripts)

3. InitScripts

   see files under etc/init.d/ directory

   PH

4. Shipped tools
   1. squashfs-tools

   PH

   1. crypt-xor

   PH

   1. cksfv

   PH

   1. gdb

   PH

   1. wget

   PH

   1. gzip

   PH

   1. fbset

   PH

   1. mc (don't try to call it direct, make ssh connection to tv and call mc.sh)

What you have to do before ask 1000 times answered questions

1. Read here

   http://forum.samygo.tv/viewtopic.php?f=5&t=96#p540

   so you now know how to disable unneeded services and where to set the username and password for windows shares (for editing the init-scripts under windows -> use Notepad++ or an other editor that can handle unix files!!)

2. File attributes

   don't copy/extract the extensions on ntfs formated usb-hd just vfat (fat32)

   keep the execute attributes correct!

   the init-scripts have the execute bit to set, this is already done

   but if you extracted the archive to a NTFS formated usb-hd this setting

   is lost! (tv mounts ntfs with special options)

   so you have to use an usb-pen or reformat your usb-hd with

   vfat before use it.

3. Media file sizes

   upnp (djmount svn version), cifs and nfs, i tested video files up to 8813360067 bytes (h264/720p mkv)

   server software:

   • upnp: ushare 1.1a (DLNA disabled!)
   • cifs: samba-server 3.2.3
   • nfs: kernel level nfs server (nfsd4)

   ff and seek is (over wifi network) tedious, you can play around with mount parameters in:

   SamyGO/etc/init.d/04_04_samba.init

   SamyGO/etc/init.d/03_03_nfsmount.init

   if you can't access/play your big fat files try to split them, problem is at server side not in "SamyGO Extensions" or TV

4. Subtitles

   tested *.srt files -> no problem over upnp (djmount), cifs and nfs

   naming sheme:

   MyMovie.srt

   MyMovie.wmv

Advanced usage (obsolete, with v0.03.6 you have a working enviroment after ssh login)

If you have started the extensions, General usage

you can ssh to your tv (ssh root@<tvs ip>)

after the login you can execute the command

source /dtv/SGO.env

or

. /dtv/SGO.env

so you get an usable enviroment (sets PATH and LD_LIBRARY_PATH for the binaries)

to get more extensions working, you can copy them into the SamyGO directory structure (like SamyGO-WiFi-Extension-Addon)

Debug

if some parts of the "Extensions" won't work on your tv, you can try to telnet/ssh to tv and execute the "Extensions" in a verbose shell

sh -x <where_extensions_are_installed>/rcSGO &

and than try to start the specific script also in the same way, like:

sh -x <where_extensions_are_installed>/etc/init.d/04_04_samba.init start

may you can see whats wrong, if not attach relevant parts of output to your support question

File Share under Windows7

• may helpful (Screenshoots from german Windows, but i hope you will find the settings)
• uninstall windows live essentials 2011
• windows update installs live essentials again
