$ ip link set can0 type can bitrate 50000 triple-sampling on
$ ip link set can0 up
  • Type the following to the shell of board 1 (which is used for testing receiving over can0 device):
$ candump can0
  • Type the following to the shell of board 2 (which is used for testing sending data packets over can0 device):
$ cansend can0 0x11 0x22 0x33 0x44 0x55 0x66 0x77 0x88
