when I use “candump can0”, I can receive can massages from my device.
but when I use “candump can1”, and connect can port to can-6(can-f), I cannot receive can massages, why?
of course, I have already set ip link(bitrate) for can0 and can1.

Dear SteveNV,
Thanks fot the reply. I think I have solved the problem now.
But,one more question: how can I collect Canbus messages from Tegra B and display them in Tegra A?
