Configuration/Test

Configuration

Connect CAN0 to CAN1

CAN0_D+ connect to CAN1_D+

CAN0_D- connect to CAN1_D- 

# ip link set can0 up type can bitrate 125000
# ip link set can1 up type can bitrate 125000


Test

#candump can0 &

#cansend can1 -i 0x00 0x11 0x22 0x33 0x44 0x55 0x66 0x77 0x88

CAN0 retrieves the data 

interface = can0, family = 29, type = 3, proto = 1
can0 []
