S32KDS Fails to use LDF file for LIN configuration

[partis]

Hi

I am creating a project with an S32K144 with the NXP supplied LIN stack and drivers. I have an LDF file, generated via export from NI XNet Database Editor, but S32DS gives a rather abrupt error of when trying to use it:

Issue: %error Error: BEV_LIN_File.ldf line: 91 "}"- Syntax Error...
Level: Error
Type: Tool problem
Tool: Peripherals
Origin: Peripherals
Resource: Sources
Information: %error Error: BEV_LIN_File.ldf line: 91 "}"- Syntax Error...

The line is a closing bracket for a "Node_attributes" section. I cant find any issues with the level of brackets or indeed any signs of an error within the file as a whole.

Is there a method of getting the S32DS tool to give a little more information on what it doesnt like to aid in finding this problem?

Kind regards

Hi @partis,

Based on the your ldf file, I found some issues. You are missing some information as below:

• The error signal that shall be published by the specified slave node.
• The <attributes_def>  field in <Node_attributes>.

You can refer to Chapter 9 of LIN_Specification_2.2A.ldf to more detail.

Anyway, I updated the ldf file to fix all of them and sent back to you(Attached).

Best regards,

Dan

Hi nxf78987

Many thanks for that.

Can you recommend a tool which allows the editing of this file via a "user friendly" GUI instead of a text editor, for use by our customer? We have used the National Instruments tool but generated LDFs which can not be used by the S32DS parser.

Kind regards

Hi @partis,

I don't know any other tool that can work that.

Best regards,

Hi,

I do not think S32DS gives you more info on the error.
Can you specify the S32DS and SDK/RTD version you are using?
Also are you able to share the LDF file you have?

Hello

I have attached an example LDF which fails to be read by S32DS. The versions are:

• S32DS - Version: 3.4 Build id: 201217 (Update 3)
• S32K144_SDK - v4.0.3
• FreeMaster_S32K144 - 2.0.0 (not being used as far as I can see)
• AMMCLIB - 1.1.22

I have tried different permutations of brackets, identifier lengths, etc; but to no avail. I am sure this is something obvious once I know

Kind regards
