Getting Started with Tizen RT

Installing the GNU ARM Toolchain

To install the GNU ARM toolchain:

Note

Only the 4.9.2 and 4.9.3 versions are currently supported and tested.

  1. Download the built-in binaries and libraries (gcc-arm-none-eabi-4_9-2015q3-20150921-linux.tar) from https://launchpad.net/gcc-arm-embedded/4.9/4.9-2015-q3-update.

  2. Untar the gcc-arm-none-eabi-4_9-2015q3-20150921-linux.tar file and export to the following path:

    export PATH=/home/xyz/currentwork/workcommon/toolchain/armgcc492/bin:$PATH

    Note

    The above command is an example only - do not copy-paste it directly. If you have multiple toolchains, modify the path appropriately.

    In Ubuntu 13.10 and higher, if you cannot execute 32-bit packages, use the following command:

    sudo apt-get install -y lib32z1 lib32ncurses5 lib32bz2-1.0

Getting Source Code from Git

To get the source code, run the following commands:

    $ git clone ssh://<Your ID>@review.tizen.org:29418/rtos/tinyara
    $ cd tinyara
    $ TINYARA_BASEDIR="$PWD"
    $ cd "$TINYARA_BASEDIR"

The TINYARA_BASEDIR environment variable is meant for reference and is used later.

Note

To get the source code from GitHub, instead of git clone ssh://..., use the following command:

$ git clone https://github.com/Samsung/TinyAra.git

Building Tizen RT

To build Tizen RT:

  1. Configure the build from the $TINYARA_BASEDIR/os/tools directory:

    $ ./configure.sh <board>/<configuration_set>

    For example:

    ./configure.sh sidk_s5jt200/hello_with_tash

    The command copies the configuration set for the particular board into the $TINYARA_BASEDIR/os directory. The configuration can be modified by running the make menuconfig command from the $TINYARA_BASEDIR/os directory.

  2. Initiate the build from the $TINYARA_BASEDIR/os directory:

    $ make

    The built binaries are located in the $TINYARA_BASEDIR/build/output/bin directory.

The following boards and configuration sets are supported:

  • Boards

    Tizen RT currently supports 1 board, the sidk_s5jt200 (Samsung IoT Development Kit for S5JT200 chipset). This board is not yet available in public markets. sidk_s5jt200 and other boards for Tizen RT are coming soon.

  • Configuration sets

    There are 3 configuration sets for sidk_s5jt200:

    • tc for running unit test cases
    • kernel_sample for running kernel functions
    • hello_with_tash for running a hello example

    You can modify the configuration by using the menuconfig tool in the os folder, but not all configuration combinations are fully tested yet.

    The IPv4 network stack based on LWIP is included, but Wi-Fi-related code, such as wpa_supplicant, is not included. Wi-Fi is to be added in 2017.
