    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 […]

  • A V4L2 staging driver for the Raspberry Pi (RPi) was recently merged into the Linux kernel 4.11. While this driver is currently under development, I wanted to test it and to provide help with V4L2-related issues. So, I took some time to build an upstream kernel for the Raspberry Pi 3 with V4L2 enabled. This isn’t a complex process, but it requires some tricks for it to work; this article describes the process. Prepare an Upstream Kernel The first step is to prepare an upstream kernel by cloning a git tree from the kernel repositories. Since the Broadcom 2835 camera driver (bcm2835-v4l2) is currently under staging, it’s best to clone the staging tree because it contains the staging/vc04_services directory with both ALSA and V4L2 drivers:

    There’s an extra patch that it is required for DT to work with the bcm2835-v4l2 driver:

    You need to apply this to the git tree, in order for the vciq […]

    The OSG Gears Up for Korea

    Considering that our primary headquarters is in South Korea, it only makes sense that open source conferences in Seoul are a bit of a big deal to us. Next week we have two major conferences there: Korea Linux Forum and the Samsung Open Source Conference (SOSCON).  We are pulling all the stops for these conferences and are sending most of our team for three days of technical discussions and networking. If you are going to be at either of these events next week, keep an eye out for our team. We have quite a few people who will be giving presentations on both technical and non technical subjects, so here’s a preview of what we’ll be talking about. Korea Linux Forum You can find the full event schedule here. Why is Open Source R&D Important and What are We Doing About it? – Ibrahim Haddad (opening keynote) Ibrahim Haddad, the […]
