Connect CAN0 and CAN1(需将patch植入)
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:
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
