is there a way to empty the tx buffer ?Usually the buffer does not get empty due to a problem of the CAN controller and/or the CAN network. So even if you could flush the queue the CAN controller is probably still stuck with his processed frame.
On my interface, the TX frames time out after one second. But I could find nothing in the spec to say that this is how things should operate. Is this driver-specific or is there something in a document that says how retransmission and timeouts works? Thanks, -- Andrew Bell andrew.bell.ia@gmail.com
