2. Samsung Open Source Group 2
Embedded developer feedback
● Joined Tizen in 2013:
– worked with Intel and now Samsung
– Mostly as platform developer
● Hardware for platform development
– GNU/Linux based Operating Systems :
● Tizen, Yocto
● Demonstrated with IoT experiments

3. Samsung Open Source Group 3
Tizen is an Operating System
● For consumer electronics
– Open to application developers
– To be connected by 2020 (IoT)
● Free and Open Source Software
– Based on GNU/Linux
– Hosted by LinuxFoundation since 2011
– Platform developers welcome

4. Samsung Open Source Group 4
Single Board Computers (SBC)
● Are for developers not like end user products.
● Support lot of I/O, Peripherals GPIO
● Many use cases :
– DIY, Robotic, Server, Web, NAS, Gateway, IoT
– Use Tizen, or prototype custom profiles
● May support (many) Linux Operating Systems.
– Yocto/OpenEmbedded can be helpful

5. Samsung Open Source Group 5
Strategy
● Official Tizen support
– Binary released on Tizen.org : OS images and packages
– Built with Git Build System (GBS) and MIC
● ARMv7, x86 (32 or 64bits)
● Official Yocto Poky support
– Cross compiling the whole OS
– Can support extra Board Support Package (BSP)
● Tizen Yocto ports
– Forked from Poky dizzy version + BSPs
● Community ports
– Custom built kernel + device trees along official RootFs

6. Samsung Open Source Group 6
Few Hints
● Watch for legal concerns (drivers as binary blobs)
● Important for Tizen
– Kernel version
● Tizen:Common uses SMACK and LSTI kernel (3.14+)
– Graphics : X11 or Wayland ? Drivers / blobs ?
● Tizen:3 is focused on wayland
● Important for IoT
– Connectivity, Security
– Power Consumption, better use MCU and not Linux

7. Samsung Open Source Group 7
Internet of Things with
● IoTivity is a framework to provide
– Seamless Device to Device connectivity for IoT
– C/C++ library (FLOSS : Apache 2.0)
● Implementation of Open Standard
– Open Connectivity Foundation (OCF)
● Supported in Tizen:3.0, Yocto, others OS and MCUs
● Cross Platform, multi profiles & protocol agnostic
– IP, Ethernet, WiFi, Bluetooth, BLE, Zigbee, LTE...

8. Samsung Open Source Group 8
History

9. Samsung Open Source Group 9
Allwinner based devices
● Achievements on Olimex OpenSource hardware
– Tizen:2.x hacks : RootFs from RDPQ's images
– Tizen:3.0:Common on OLinuXino micro (A20) TDC2014
● Allwinner SoC
– Support form linux-sunxi community : 3.4 (No Security)
– - : MALI GPU : no support for wayland
– + : Framebuffer
● https://wiki.tizen.org/wiki/Sunxi
● Next ? : Mainline kernel, C.H.I.P ?

10. Samsung Open Source Group 10
MinnowBoard Max
● Reference platform for Tizen:3.0:IVI (based on Common)
– Intel Based (E3815), Open Source Hardware
– https://wiki.tizen.org/wiki/MinnowMax
– Supports web apps (.wgt), Accelerated graphics...
● Download EFI x86-64 image :
– tizen-3.0.2015.Q2-common_20150630.1
– http://download.tizen.org/releases/milestone/tizen
● Dump to USB or Sdcard:
file=”tizen­3.0.2015.Q2­common_20150630.1_common­wayland­efi­x86_64­sda.raw.bz2”
lsblk ; disk=/dev/sdTODO # update device
bzcat "$file" | sudo dd of="$disk" bs=32M oflag=sy

12. Samsung Open Source Group 12
Odroid U3 & XU4
● By HardKernel, ships Exynos CPU
– Note: Not on all Odroids (ie: C1 uses Amlogic)
– Uses signed u-boot mechanism : ARM Trust Zone
– ARM Mali GPU
● Official Tizen:3 support
– GPU support with DDK
– + : Closer to products

13. Samsung Open Source Group 13
Raspberry Pi
● RPI2 ARMv7 : efforts by S-OSG
– using Tizen Yocto (TDC2015)
– but could use GBS too
● RPI1 and RPI0 (ARMv6)
– so Tizen Yocto
● Graphics : BCM Video Core
– Userland : Legacy
● Does not work well with Wayland
– DRM : Mainline support
● To Upgrade Kernel, mesa, xwalk

14. Samsung Open Source Group 14
Raspberry Pi Zero
● Super cheap: 5 GBP
● Lacks connectivity but provides USB
● ARMv6 : Like PI1 : not supported on Tizen Infra
● So Tizen Yocto !
● More: OSIS2016

ARTIK just landed !

18. Samsung Open Source Group 18
● Modules for IoT & Cloud
● ARTIK5 & ARTIK10 : Exynos5 based CPU(s)
– Multimedia : ARM MALI
– Connectivity :
● Ethernet, WIFI, Bluetooth, BLE, Zigbee, SigFox...
– Others : Security (ARM Trusted zone)
● ARTIK1 is MIPS
– Not appropriate to run Linux

Conclusion
● It's up to you to define what are your priorities :
– Cost
● RaspberryPI0, PI1, PI2, Odroid C1
– Connectivity, I/O, IoT :
● ARTIK5, ARTIK10, Atmel, PI3
– OSHW :
● Minnowboard Max, Olimex
– Align to Tizen platform developers
● Exynos SBCs : Odroid XU4 or ARTIK

28. Samsung Open Source Group 28
Summary
● Many single board computers on the market
– Most are supporting Linux or even Yocto
● Few are supported by Tizen project : x86 or ARM Exynos
● Others can be adapted somehow
– Accelerated graphics can be difficult for hobbyists
– Fallback on headless use cases (I/O, server, IoT)
● IoT is fun with IoTivity
– Interact with other devices or commercialized products
– ARTIK is focused on IoT use cases too
