Hi Pankaj,

CAN Bus is functional in both directions, rx and tx .

1. cansend works properly
2. candump also works properly

I'm just trying to verify if it's just me or the bcm.
I expect a usage error because I run a non-modified debian 8 image on
the BeagleBoneBlack, which shows exactly the same behaviour.

Thanks and Best Regards,
Patrick
