Hi Andrew , I think you misunderstand me.I couldn't active BBB's CAN legs.So i couldn't use CAN .Then i couldn't find to using of CAN Bus with BBB .So i want to learn Beaglebones Black's how to CAN leg could do active and starting communication.But at this link commands didn't work.(http://www.embedded-things.com/bbb/enable-canbus-on-the-beaglebone-black/)
