CAN Bus Cape RevA
The BeagleBone CANBus Cape makes use of DCAN1 interface of the AM335x processor to provide a Controller Area Network (CAN) interface that meets the specifications of ISO11898. The CAN Bus interface can be accessed via a standard D-Sub 9 female serial connector. This connector is located to the side so it doesn't interfere with any capes stacked above it. The BeagleBone CANBus Cape also supports SocketCAN.
- There is a hardware bug on the CANBus, where the buffer U27 blocks the TX signal coming from BeagleBone. One workaround for the issue is to remove the buffer and short pin 2 and 4 of U27. Please request an RMA for your board if you are not comfortable with the solder job. Rework will be done at no cost.
- BeagleBone CANBus Cape revision A1 is supported by Angstrom release 06-18-12 or later.
