Hi, Wolfgang,

I got this error with my advantech PCM26D2CA CAN-board when real-time applications were running.

The PCM26D2CA board has two ports: "rtcan0" was used by user applications and "rtcan1" was used by "rtcanrecv" to monitor CAN bus.

The bitrate was set previously and not set explicitly here.

Could you give me some help please? Thanks!


Good luck!
