This issue is still open.. Could you guys add some more details on it.
In nutshell, it should load the sketch as the sketch files gets loaded in root/sketch directory.
We tested it with : iot-devkit-prof-dev-image-edison-20160606
Thank you for contacting us.
The behavior you describe, where the Edison doesn't run the sketches automatically after reboot is a known issue and has been reported before. There's a workaround that you can try that will enable the Arduino sketch to be run after reboot. You can find it here /message/319509# 319509 https://communities.intel.com/message/319509# 319509 .
We'll bring this case to the attention of the proper team, so they know that there are users in the community still asking for this to be enabled.
Thank you for the feedback!
