[LIN Stack] Error bit is set master node sends only header but no data bytes

SorinT — Wed, 14 Sep 2022 15:44:00 GMT

Hello,

I am having an issue with the LIN Stack from the S32SDK RTM 4.0.2.

I am using the S32K144 uC, configured as LIN slave.

It seems that when the master node sends a frame header but without any data bytes (frame is supposed to be published by master), our LIN stack sets the error bit when it shouldnt.

According to the LIN specifications (LIN 2.1 Specifications chapter 2.7.4), the error bit should be set when there are errors in the response field, but should not be set when there is no response at all.

Could you please support me in finding the root cause? Maybe I am missing somethinh?

Best Regards,

Sorin
