Hello guys, I have the same issue, indeed all the UARTs coming disabled with this image, even though all the /dev/ttyOx are available. My solution maybe is not the best one, but I just change the version of Debian 7 release 2015-07-13, and everything works like we expect, I mean like books and tutorials about how to enable ports, and these stuff. Later I will try the RobertCNelson solution, it looks very well, maybe is a more reliable solution.
