就是咱们硬件上用CAN1和CAN2引脚,但加载后,开发板可以查看到can0和can1
root@firefly:~# ip link set can0 down
root@firefly:~# ip link set can0 type can bitrate 250000
root@firefly:~# ip link set can0 up
root@firefly:~# ip link set can1 down
root@firefly:~# ip link set can1 type can bitrate 250000
root@firefly:~# ip link set can1 up
root@firefly:~# ifconfig

而且从实际使用上看,
can0设备对应CAN2引脚
can1设备对应CAN1引脚
请问这个是怎么回事?
另外,我的项目里想用3个can,那can0被占了可怎么办?
