LIN Break Detect Interrupt not getting detected in S32K

Hello,

I am trying to make LIN working.

Below are my setup details:

1. Using S32K146EVB-Q1XX board.

2. Autosar stack for configuration of LIN

3. LPUART2 port/Module is used for LIN

after running the code, I can see that I am able to transmit the LIN Break field but after this ISR is not getting triggered?

1. We have used Interrupt priority 32 and interrupt source as 51

2. Also checked in NVC register that interrupt is enabled

3. LBKDIE bit enabled in Baud Rate Register

4. LBKDE bit enabled in Status Register

5. DATA register is used to send break field

so below are few questions:

1. Do we need to place the jumper to use Power adapter for LIN in evaluation board or USB power will also works ?

2. What can be other causes of not detecting LIN break field?

Hi,

the transceiver is supplied by VSUP/VBAT, so it is a must to use external supply, not just USB. I guess that this could be the reason.
