The company provides support for Android 7.1 and a Linux distribution with Qt, but there’s zero information on their website about software,
and was not able to get answer by email in time for this article. [Update: email reply:
The Linux and Android are ready.And Ubuntu core is under development.
We prefer to put the SDK in the Github in the Q2 of 2018.
To help with development, a cute and compact evaluation kit is also offered with a large heatsink.
