LIN not working in S32K148EVB Q176 (Rev B)

[emb02]

Hello, community

I want to test the LIN on S32K148EBV Q176 board (Rev B). I'm using schematic SCH-29644 REV B for reference.

The schematic indicates that the development board uses the UJA1132HWF5V4 IC LIN chip, but in the development board UJA1131HWF5V0 IC LIN chip is mounted.

The UJA1131HWF5V0 has a single LIN provision (LIN1) so not able to use LIN2 for testing.

So I'm using the LIN1 but not able to receive data. I have tried both the LIN master and slave example code without LIN stack.

Could you please provide me the solution to get frame on LIN 1(J13) using MBDT.

Hi,

if you run LIN Master example are you able to see LIN Frames on your LIN1?
LIN master always sends LIN header and either publish data or request data from slave, this would be visible on the bus. Then you need some slave connected (LIN tool, other board) to it which provide a response to respective PID.

BTW, if need MDBT related demo, rather search or ask on MBDT community directly;
