Not able to test S32K142 slave configuration

Hello,

I am trying to test the sample LIN Slave configuration as provided by NXP SDK but as they are not using the LIN connector on S32K142 Eval Kit I have changed the code to use the LIN Connector (LPUART0 and PTC2 and PTC3 pins).

I have loaded the ldf in CANoe to configure it as Master but the CANoe given error saying slave is not responding.

I am attaching the code and ldf that I am importing in CANoe, please let me know if I am missing anything.

Also let me know if anything else needs to configured in CANoe.

Thank you.

Hi,

what kind of board revision you have?

On rev.C LIN transceiver is connected to PTD6/PTD7 only.

On rev.D there could be more options but as per schematic, by default, it is connected to PTB0/PTB1 using zero Ohms resistors

So try to select PTB0/PTB1 in pin muxing component.

Also be sure board is using external 12V power supply so LIN transceiver is powered.
