Connect CAN0 and CAN1'(基于Debian11 DIV130311版本,植入CAN2.0相关patch)'

RK3568不支持CAN-FD功能,参考Errata(提取码:a887),变更为CAN2.0功能。


架设环境:

将CAN0与CAN1接口短接

CAN_D0+——>CAN1_D+

CAN_D-——>CAN1_D-

如下图

RTENOTITLE

输入指令:

# ip link set can0 down
# ip link set can0 type can bitrate 1000000
# ip link set can0 up
# ip -details link show can0
# candump can0 &
# ip link set can1 down
# ip link set can1 type can bitrate 1000000
# ip link set can1 up
# ip -details link show can1
# cansend can1 123#55
can0  123   [1]  55
