Thank you very much to Robert Nelson, Andrew Frazer and Sam Nazarko. We will put together a webpage with all the information about how to install it. If you would like to try the Kernel 3.15, have a look at Roberts github: https://github.com/RobertCNelson/imx-devel/tree/v3.15.x-rex. You can also download the clean Debian filesystem generated by Sam at: http://www.imx6rex.com/imx6-rex-debian.tar.gz
