Regarding LIN communication issue with S32K148-Q176

[Bhavesh_Raju]

Hi,
I am trying with the lin_master_S32K148 example for the board S32K148-Q176. I am not able to receive any frames from the LIN pins. Can anyone please help me with this?

Hi @Bhavesh_Raju,

The SBC UJA1132 is the LIN tranceiver on the board.

Is the SBC powered by 12V (J9, VBAT)?

Select P5V0 of the MCU to P5V0_V1SBC too.

BR, Daniel

Hi @danielmartynek 

In my board, SBC UJA1131 is present I checked on the board. In the lin_master_s32k148 example, what changes are required to receive the frames for UJA1131 we have one LIN interface connected to LPUART0 can you please share the steps I have to follow to get frames from the LIN1 with the above mentioned example?

Hello Bhavesh Raju,

The example uses LPUART2

pins PTA8, PTA9

This is the LIN2 interface (J17) on the board:

Can you just use LIN2 instead of LIN1?

Thank you,

BR, Daniel

Hi @danielmartynek,

I tried with LIN2 it's not working. After changing some configurations I am receiving frames on the LIN1. Thanks for the support.
