Hi Guy, Thanks a lot again! :) It's great information!
I wrote to you in another thread<https://groups.google.com/forum/embed/?place=forum/beagleboard&showsearch=true&showpopout=true&showtabs=true&hideforumtitle=true&parenturl=http%3A%2F%2Fbeagleboard.org%2FCommunity%2FForums#!category-topic/beagleboard/beaglebone-black/LyVMQk4EyvE> that even without compiling the DT Overlay file that should have set the P9.15 to mode 7, I managed to turn on/off and output of P9.15 as if it was GPIO.
