What do you know, Tizen running on a 3rd-party device! Developer duo xjobb from ST Ericsson has done a great job running Tizen 1.0 Larkspur from a Micro SD card on Snowball – a low power, low cost Single Board Computer based on the ST-Ericsson Nova A9500 processor (Dual Cortex A9 + Mali 400 GPU).
Their main goal is to run Tizen smoothly on Snowball. The project page and full instructions are at the Igloo Community wiki.
