If you go to http://cdimage.ubuntu.com/non-ports/rel ... 4/release/ you can see an image of Ubuntu 12.04 for the Freescale imx53 development board.

Efika Mx still use imx51 so I think it doesn't run on it, but with the right kernel for Efika mx ( the new 3.2) it will be possible to run it?

And the new Efika Mx with imx6 will use Ubuntu 12.04 ?
