S32K3 How can LIN better obtain data when it is the master?

[wuxianlong]

Hi,NXP

When LIN is the master, in the interrupt function, there is no relevant API to notify the user, and the response data of the slave cannot be obtained in time. LinIf_RxIndication can only be used in slave mode.

I can only get data through Lin_43_LPUART_FLEXIO_GetStatus. Is there a better way?

Best regards,

Thank you for your patience. 
Here is the response I received from the software team this morning:
The function LinIf_RxIndication is only applicable for slave nodes because is an AUTOSAR standard indication.  

The standard also mentions that Master nodes have to use the Lin_GetStatus()  

This is the indication of AUTOSAR for automotive implementations and our drivers are based on that. So, this is the better way to obtain data of a LIN Master Node.

Hi xianlong,

Seems that you are using LIN STACK.  You are right, the LinIf_RxIndication is for slave.

I need to consult this with SW team and will update this thread as soon as I have their feedback.
