UCM-iMX95 Yocto Linux: CAN

CAN bus

CAN bus interface is available on the evaluation board on header P17.
For more details, please refer to the Hardware Guide

Operation Example

• Obtain another board with CAN
• Short jumper E6
• Connect:

DUT                     Device 2
CAN_H (pin 2) --------  CAN_H
CAN_L (pin 6) --------  CAN_L

• Configure both CAN interface bit-rate to 1 Mbit/sec:

ip link set can0 up type can bitrate 1000000

• On both system, listen to received data frames as well as error frames:

candump any,0:0,#FFFFFFFF &

• Send data from one system and expect to receive it on the other:

• Standard frame:

cansend can0 111#1122334455667788

• Extended frame:

cansend can0 11111111#1122334455667788

• Generate 50 random extended frames with 50 msec interval between each:

cangen -g 50 -e -D r -v can0 -n 50

• Disable the interfaces:

ip link set can0 down
