    Building IoTivity for ARM on ARTIK Devices

    There are several options to build IoTivity for ARM targets or any non x86 hardware, but first you have to decide which operating system you want to use. In this article, I won’t compare OS or devices; instead, I’ll give a couple of hints that apply to ARTIK 5, 7, and 10 devices (not the ARTIK 0 family, which run TizenRT). These steps can also be applied to other single board computers like the Raspberry PI. Build for Tizen with GBS The first and easiest way to build IoTivity is for Tizen, using GBS. This process was explained in a previous article on this blog: An Introduction to Tizen Development on ARTIK For your knowledge, GBS was inspired by Debian’s git-build-package and uses an ARM toolchain that runs in a chrooted ARM environment using QEMU. Both ARTIK boards and the Raspberry Pi are used as Tizen reference platforms. Build for […]

    How to Run IoTivity on ARTIK with Yocto

    Samsung ARTIK is described by its developers as an end-to-end, integrated IoT platform that transforms the process of building, launching, and managing IoT products. I first saw one a year ago at the Samsung VIPEvent 2015 in Paris, but now there is an ARTIK10 on my desk and I would like to share some of my experiences of it with you. In this post, I will show how to build a whole GNU/Linux system using Yocto, a project that provides great flexibility in mixing and matching components and customizing an environment to support new hardware or interesting software like IoTivity. If you’re looking for Tizen support, it’s already here (check at bottom of this article), but this post will focus on a generic Linux build. Many of the board’s features I will be covering in this article are briefly introduced in the following video: https://youtu.be/7ZUYF21d1zo?#iotivity-artik-20160505rzr.mp4 There are 3 ARTIK models […]

    IoTivity is Getting Ready for Automotive

    Samsung has recently intensified its focus on improving the driving experience with the launch of Connect Auto. As a coincidence, I tried to put together different efforts from our group to into an open connected car experiment. Check out this video which shows a DIY Tizen fan that’s controlled from an Automotive Linux system and Tizen TM1 mobile device: It’s All About Interoperability It might look a bit over-engineered with all of the devices in this demonstration, but the purpose is to validate communication between devices on a network (WiFi, BT, BLE) in various contexts. Of course, it’s possible to adapt the DIY fan to use an automatic gate mechanism or something else to interact with the driver, or it could even use cloud services that ensure the necessary level of security. Interoperability is the key word here, I believe we’re headed in the right direction following the recent Open […]

    RPi2: Getting Smart on Tizen

    Once you’ve got Tizen running on your Raspberry PI 2 (RPi2) using the procedures described in Tizen on RPi2: Now Supporting 3D Acceleration, you will probably want to be able to dynamically add/remove packages. It’s a pain to be required to rebuild and flash your OS every time you want to change the included software, so following this tutorial will help make this much easier. This small tutorial shows how to install the smart tool that is shipped on Tizen, but is not installed by default. 1) Add Smart to the RPi2 Image The first step is to add the Smart Package Manager (python-smartpm) to the RPi2 Tizen image. This is the same package manager used on Yocto, and Tizen has its own patches for it. In order to install it, you should apply the following simple patch on your Tizen repository:

    If you are unfamiliar with the patching […]

    Tizen on RPi2: Now Supporting 3D Acceleration

    In Bringing Tizen to a Raspberry PI 2 Near You… I described the work we completed to port Tizen to Raspberry Pi 2 (RPi2). Since then, the Samsung Open Source Group has worked hard to add support for 3D acceleration. UPDATES: Added the -dev images, as they’re now supported. Added bitbake command for building the crosswalk-dev image Added command line for ddrescue The Kernel was updated to Vanilla Tizen Kernel 4.4 This is an update to our original guide that describes how to build a custom Tizen image for the RPi2, and it now includes instructions to enable 3D acceleration. This is based mostly on work completed by our own Derek Foreman. Please note that this uses a driver that is still under development (VC4), written by Eric Anholt from Broadcom, so we don’t recommend its use in production situations. If you don’t want to wait through the build process […]
