Hi Joel, Ake, Steffen,

thank you for your Ideas.

My Application is still insufficient to detect a faulty Bus or 
faulty Node.

I fixed some Things in Software that was not quite clear to me 
before, as good as the fact that the CAN Controller must have a 
recover time between Bus Off and Restart, that means that the CAN 
Controller not simply can reset.

Nowadays, when Bus Off occurs, after clearing RM I can monitor the 
Count Down from TxErr Counter, and after them the CAN Controller 
runs properly.

Bus Off can occur 3 or 4 or 5 Times, until the CAN Controller is 
nevermore able to restart. In this case, after clearing RM, The 
TxErr Counter shows always the value 0x88, RxErr is 0, and the 
Controller is hanging.

Very strange, at this way it is not really possible to resume the 
CAN Bus Operation for at least a few specified times at a run time.

I'll try a solution on another time.

Greetings

Dietmar
