Banana Pi M2M Keyboard Putty

Hello, I recently got my M2M and got Ubuntu Server 16.04 running. I am able to connect to the board through serial with Putty, and everything displays properly. However, I cannot type anything on the console. I have the correct baud rate and the uart connections are correct.

Thank you.

Figured it out. You have to add enable_uart=1 to the config file in the root directory.
