Now the situation is:
CAN communication on both sides of the baud rate for the 500 k at present, my one end of the embedded devices is CAN communication, on the other side is a PC software, now through the PC software to upgrade my equipment issued to upgrade package, after the upgrade is complete my device CAN baud rate is 400 k, now do not match the baud rate, equipment CAN status to busoff,

Another case is that the initial state of my equipment and PC software is 400 k, if issued by PC software upgrade package, rise my device CAN baud rate is 500 k, then I busoff state of equipment CAN not appear, but the normal passive, could it be the end of the PC software CAN appear busoff?

So could you please tell me: CAN communication because the baud rate CAN lead to different CAN baud rate lower side of the CAN for busoff state? Why do two things I CAN the state of the equipment will not be the same?
