Tizen has previously made its way onto the Raspberry PI 2 Development Board, but 3D acceleration was not working at that point. Well, the good news is that the Team over at the Samsung Open Source Group have got the 3D Acceleration working now.
There is a new procedure and it is now possible to build the standard Tizen images, including tizen-common-core-image-crosswalk. The article describing the procedures can be found at: http://blogs.s-osg.org/tizen-r
Thanks to Mauro and the Team for their efforts.
