'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：
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
