I have noticed that if I short CAN_H and CAN_L together, or if there is noise on the bus, the BeagleBone will stop sending and receiving CAN messages. When this happens, if I execute "ifconfig can0 down" and "ifconfig can0 up", things start working again. Is there a way to detect this automatically and recover? I'm using SocketCAN, but haven't found anything that would tell me when I get a bus off or bus heavy.
