Hi essamamr,
You cannot connect 2 controllers with each other without transceiver. Follow this doc:
https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/hw_setup_jetson_can.html#wwpID0ELHA

Thanks,
Shubhi

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

Hi,
CAN0 to CAN0 is possible and CAN1 to CAN1 is possible.
Can you share your steps and explain how have you confirmed that without transceiver and connecting CAN0 to CAN1 is transferring messages?
Please share details.
