Hi,

this status shows a bus off is entered and bus off recovery is also finished.

The bus off indicates wrong configuration, either bit timing, pin setting or similar, thus bit errors must be detected and the message cannot be successfully transmitted.

So please give more info about

- the board you have and can bus connection

- the example you run

- measure CAN bus with scope or some analyzer

BR, Petr
