Disabling UART console debugging in BB black


I want to use UART0 of Beaglebone Black board for my application but it doesn’t seems to be working.

I did some research and figure out thet UART0 is used for serial bug console as default.

Now I want to now how can I disable the default debug console and use UART0 for my application.

I am using Ubuntu 14 as OS.

Pls help me to resolve this issue.
