| Edison mounted on mini breakout board. Canadian Quarter for Scale. |
If your not familiar with the Edison, its a system on module device containing a dual core Intel Atom CPU (32bit @ 500 Mhz), 1 GB of LPDDR3 RAM, 4 GB of eMMC flash storage, and built-in wifi. At 35.5 x 25 x 3.9 mm it is arguably one of the smallest machines I've seen run an Apache Karaf based system.
My build utilizes a Yocto Linux OS build for Edison, and a standard 32 bit Oracle JDK 1.7.0 installation. Downing loading utilities onto the Edison was a small challenge in that the version of wget that ships with Yocto does not support https, to get around this I used SCP to copy files over to the device.
Out of the box I only had to make one customization to the OpenDaylight setenv script:
- The set environment script (setenv) had JVM parameters for PermGen and Max Memory set higher than the Edison could support. I set these values to 340MB for PermGen, and 756MB for Max Memory. These are not optimal settings, but will work well enough to get things going.

Now to verify the installation is running correctly, I started up the OpenDaylight Toaster demo.

I've posted to my github page my notes and files for getting OpenDaylight Helium running on Intel Edison. I'm looking forward to seeing what the community makes on the platform.
