Enabling the PWM in Beagle bone black Rev C is bit difficult.

[Santhosh]

Hello Team,

I am new to this Beagle bone board. I started learning since few days- could you please help us in configuring PWM pin P9_14.

Currently i am using Adafruit library PWM

IOError: [Errno 2] No such file or directory: '/slots'

Thank you,

Santhosh

stuff
