| 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. |
