It's running on s32k144 microcontroller. But I simulated some data on the bus with PCAN it cannot be received by RX message buffer when I debuged it. Received message buffer is always in busy state. I don't know why.
Baute rate is set as 500k for both microcontroller and PCAN. it's implemented on CAN0 and FD is false. Interupt is enabled. All configurations are OK. Connection problem is excluded. But no data exchange occured. I have no idea to do it next. Please help me.
