S32K118Q048 LIN Stack- Break Delimiter

[yousefdessouki123]

Hello,

I'm currently working with the LIN stack on an NXP S32K118Q048 and aiming to increase the Break Field duration. Based on PicoScope measurements, the current Break + Delimiter length is approximately 675 microseconds, but I need to extend it to around 940–945 microseconds to ensure compatibility with a specific slave.

From the community posts, I understand that neither the RTD nor the hardware directly exposes a configuration for this. However, it was suggested that inserting a finite delay loop before sending the Sync byte could effectively increase the break duration.

The problem I'm facing is identifying where exactly to insert this delay. I attempted modifying the Lpuart_Lin_Ip.c file but didn’t observe any effect.

I'm using:

• LIN Stack version: 2.0

• RTD version: 3.0.0

Could you please let me know the exact function name and file where I can modify the break generation timing?

regards,
