VAR-SOM-AM43 - CAN Bus
The AM43 DVK exports two CAN Bus interfaces can0 & can1
For testing CAN Bus:
- Short CANL, CANH and GND pins of the 2 CAN Bus interfaces can0, can1 (located on J11).
- Type the following into the shell for configuring both CAN bus interfaces:
$ ip link set can0 type can bitrate 50000 triple-sampling on $ ip link set can0 up $ ip link set can1 type can bitrate 50000 triple-sampling on $ ip link set can1 up
- Type the following to the shell for testing receiving over can0 interface):
$ candump can0 &
- Type the following to the shell for testing sending data packets over can1 interface):
$ cansend can1 0x11 0x22 0x33 0x44 0x55 0x66 0x77 0x88
- At this point, can0 interface will receive the data packet sent from can1 interface:
<0x001> [8] 11 22 33 44 55 66 77 88
