There is a difference on the code of SDK MCUXpresso and the processor expert bean of KDS. It is not possible to communicate CAN with other microcontrollers and the other microcontroller NXP writing the code in KDS because a mask on frame.id. I tryed everything and it is impossible to communicate. From the side of MCUXpresso when you send it stays on while(!txComplete). I modified the timing bit calculation and not happens. I can communicate between two boards writing the software on both with MCUXpresso. There is a bug on MCUXpresso that is not possible to communicate with other microcontrollers. I think that is exclusive and you should write software and use only microcontrollers wrote with MCUXpresso only. I need help to now how to communicate with others microcontrollers and the same microcontroller wrote in KDS.
