The LIN protocol stack generated in S32DS has a limit on the maximum message length.

Hello,

The LIN protocol stack generated in S32DS has a limit on the maximum message length. Where can we find the basis for this?When sending data exceeding 256 bytes, a timeout occurs. It seems that the protocol stack does not handle the situation of extremely long data.

Hi @ZEROOO,

Which S32Kxxx device are you using, and what versions of the SDK/RTD and LIN Stack are you working with?

Thank you

Hello，

The used MCU is the S32K1xx series. However, the SDK package does not have clear information. I checked the configuration in the S32DS and indeed, the length can be adjusted.
