Modifications to the [https://source.android.com/ Android Open Source Project] were made in order to support main screen mirroring on the HDMI output and to support the WiFi chipset installed on boardonboard. This chipset features the WiFi Direct protocol for screen mirroring over WiFi. As this chipset was not supported at all, such modifications were implemented not only at the customized Android device layer but also at the system, hardware, external, and platform layers. Once the WiFi chipset is supported all down to the lowest level of the software stack, the Android framework enables WiFi functionality for the device.

This SOC provides significant enhancements over its predecessors in terms of graphics performances, in fact.
