Errors creating a LIN Description file through S32DS

Hi.

I have the following question:

I'm trying to configure a Lin_Stack application project, I'm configuring it to use LIN J2602. In the component inspector window, when I configure the frames that will be sent/received, the S32DS eventually shows me that, for each slave node, there should be a response error signal (which fits well with my configuration).

However, the signal which is the response error in my LIN description file is not 3 bits long, as the configuration requires. I have a signal that will be in charge of carrying the response errors, but it is 8 bits long since it will carry other data as well.

If I try to add a signal which is not 3 bits long to the Response Error field, it gets cleared automatically. Also, if my signal is 3 bits long but doesn't have a 5-bit offset, I also get an error which shows that response errors must have a 5-bit offset.

Is there a way to set up my configuration without errors and make the S32DS recognize an 8 bit long signal as the response error signal?

Hi,

as per feedback from LIN Stack expert this is not possible, see below...

As the J2602 Spec the Error signal must be 3 bit and will be in all of slave transmission frame with offset 5. So we cannot do it.
