Only 4 CAN ports avaliable when using RTC Module?

When I connected the RTC Module to CAN_6&4, does it mean that both CAN6 and CAN4 are unavaliable?
Anyone can tell me which port is RTC actually used?

Hi Liang_Qi,

Please refer to the following link:
https://docs.nvidia.com/drive/active/5.1.0.2L/nvvib_docs/index.html#page/DRIVE_OS_Linux_SDK_Development_Guide%2FInterfaces%2Frealtime_clock.html%23

The canrtc.sh script can help you to understand the CAN interface for the RTC module.

Thanks for the help.
I checked canrtc.sh and found only can1 which corresponding to CAN6 port is used.

This means we have 5 CAN ports available.
