Candump not showing anything


I am working with Jetson TX2 development kit. I want to send data to arduino with Can communication. Before that, I tested cansend works well, but it didn’t.

sudo modprobe can
sudo modprobe can_raw
sudo modprobe mttcan
sudo ip link set can0 up type can bitrate 500000
candump can0

and the other terminal

cansend can0 123#asdf

but candump didn’t show anything. My can bus state is error-active. Also I confirmed the connection between can transceiver and TX2, but there was no problem.

I want to know why and figure out how to send data with can communication.

Thank you
