I'm working on S32K142，and use UJA1169 as the CAN transceiver.
At the end of SBC_Init(); it will set UJA1169 to Normal mode, but send an unknown frame.
After run LPSPI_SetIntMode(base, LPSPI_TX_DATA_FLAG, true); it will send a frame as below.
ID=0x40000008, type is RTR.
I don't know why send out this frame and how to avoid this performance? Could you please explain for me?
