The preloaded firmware requires a loopback between CAN Node 1 and CAN Node 2.
That means that one of the 2-pin cables delivered in the kit should be used to
connect:
CAN Node 1 pin 2 Å-------------------------Æ CAN Node 2 pin 2
CAN Node 1 pin 7 Å-------------------------Æ CAN Node 2 pin 7

2.3 Connecting the LIN interface
The Atmel AT32UC3C-EK offers two LIN interfaces to connect the board to external
LIN networks:
1. 3-pin header connector LIN Node 1
2. 3-pin header connector LIN Node 2
The pinout is hsown in Table 2-2.
