This is my step for use can-bus:
sudo busybox devmem 0x0c303018 w 0xc458 sudo busybox devmem 0x0c303010 w 0xc400 sudo modprobe can sudo modprobe can_raw sudo modprobe can_dev sudo modprobe mttcan sudo ip link set down can0 sudo ip link set can0 type can bitrate 50000 loopback on sudo ip link set up can0
I connect the jetson orin nano’s J17 pins with a CAN transciever(Waveshare SN65HVD230)'s RX and TX , and connect the CAN transciever’s H and L with a usbcan’s H and L.
For the loopback mode, jetson can receive the data as below:
And my usbcan also receive the same data, but it cannot transmit any data to jetson.
If not select loopback mode, jetson and usbcan cannot receive any data. Some log as below:
Any help would be greatly appreciate, thank you.
