Unable to use can to send after configuration

After modifying pinmux and configuring CAN, CAN communication still cannot be realized. And the following error occurs, please help to solve it, thank you.

Please refer to below thread to see if can help: Some suggestions on troubleshooting CAN interface - Jetson & Embedded Systems / Jetson AGX Xavier - NVIDIA Developer Forums

Sorry, I have followed the configuration can method you provided, and still can’t solve this problem. I use a can transceiver to connect to a can analyzer to monitor CAN signals. At the same time, I check the status of can as follows.

Hi user6138,
Please run these commads to avoid buffer space issue:
ifconfig can0 txqueuelen 1000
ifconfig can1 txqueuelen 1000

I’m closing this topic due to there is no update from you for a period, assuming this issue was resolved.
If still need the support, please open a new topic. Thanks

Is this still an issue to support? Any result can be shared? Thanks
