dwilkins / pwm-sunxi on CubieA20
Created April 7, 2014 17:01
Hello,
I need to use the PWM for my project using cubieboard2. I know this has been asked numerous times but I still do not know what to do.
This is my first time using Linux and Debian so I have no experience at all.
How do I patch my cubieboard using your files on github? Could you shed some light please on how to patch?
Right now I am using Cubian from here http://cubian.org/downloads/ and using LXDE X windows.
