Development Boards for Tizen IoT

  1. 1. Samsung Open Source Group 1 Dev boards for IoT ? From Minnow, Odroids, RPIs to ARTIK Philippe Coval Samsung Open Source Group / SRUK philippe.coval@osg.samsung.com Tizen Community Meetup NUMA Paris <2016-06-09> https://wiki.tizen.org/wiki/Category:Hardware
  2. 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. 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. 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. 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. 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. 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. 8. Samsung Open Source Group 8 History
  9. 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. 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. 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. 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. 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

  17. 17. Samsung Open Source Group 17 ARTIK just landed !
  18. 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

  26. 26. Samsung Open Source Group 26 Pick yours ?
  27. 27. Samsung Open Source Group 27 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. 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
