Intel Edison - AnaNek/tarantool GitHub Wiki

The Intel® Edison development platform is the first in a series of low-cost, product-ready, general purpose compute platforms that help lower the barriers to entry for entrepreneurs of all sizes—from pro makers to consumer electronics and companies working in the Internet of Things (IoT).

Intel Edison

Software

The device runs Yocto Linux distribution. Yocto Linux is a constructor like OpenWRT - you selects packages, configure kernel and then get firmware image in a file. Additional packages can be installed using opkg.

Unfortunally, there is no x86_64 bit distribution for this device yet. Anyway, x32 (64-bit with 32-bit pointers) should make more sense here for 1GB of RAM.

root@edison:~# uname -a
Linux edison 3.10.17-poky-edison+ #1 SMP PREEMPT Sun Nov 23 09:51:25 MSK 2014 i686 GNU/Linux

Stock firmware already has nodejs and redis (in some builds) installed by default.

Cross-compiling Tarantool

  • Get official SDK from Intel web-site. You need Edison SDK Linux 64 or Edison SDK Linux 32. OS X wasn't tested. Alternative, you can build SDK manually using Yocto Linux scripts from edison-src-weekly-68.tgz. Please take a look to Intel® Edison Board Support Package for details.

  • Install SDK to proposed folder (/opt/poky-edison/1.6).

  • Start a fresh console and configure environment:

source /opt/poky-edison/1.6/environment-setup-core2-32-poky-linux
  • Check that environment vairables were set up properly:
roman@desktop:~$ echo $CC
i586-poky-linux-gcc -m32 -march=core2 -mtune=core2 -msse3 -mfpmath=sse -mstackrealign -fno-omit-frame-pointer --sysroot=/opt/poky-edison/1.6/sysroots/core2-32-poky-linux
roman@desktop:~$ echo $CXX
i586-poky-linux-g++ -m32 -march=core2 -mtune=core2 -msse3 -mfpmath=sse -mstackrealign -fno-omit-frame-pointer --sysroot=/opt/poky-edison/1.6/sysroots/core2-32-poky-linux
roman@desktop:~$ $CC --version

  • Build Tarantool:
roman@desktop:~tarantool$ cmake . -DCMAKE_INSTALL_PREFIX=$SDKTARGETSYSROOT/usr 
roman@desktop:~tarantool$ make

Please note that -DCMAKE_INSTALL_PREFIX is needed for CMake to find libreadline headers.

Copy ./src/tarantool binary to your device via ssh. Yocto/OpenEmbeddeded recipes are not implemented yet.

Building Tarantool on Device

You can also build Tarantool directly on the device.

Please file a ticket if this build fails.

Running Tarantool

$ tarantool
tarantool> roman@edison:~/tarantool$ ./src/tarantool 
Failed to set locale to C.UTF-8
./src/tarantool: version 1.6.6-227-ga126d14
type 'help' for interactive help
tarantool> box.cfg { slab_alloc_arena = 0.5 }

Known Issues

Primary features (app server, box) work properly. Some tests in test suite fails due to missing locales.

  • Local-dependent features doesn't work due to missing locales - ignore "Failed to set locale to C.UTF-8)".
  • Default value of box.cfg { slab_alloc_arena = xx } is great than available memory - use smaller value, e.g. box.cfg { slab_alloc_arena = 0.5 }
