Issues with S32k146 EVB Lin Communication

raphael_sommer — Fri, 15 Mar 2019 08:48:59 GMT

Hello everyone,

I am using the S32k146 EVB I am using the Example "lin_master_s32k146" from the "S32K1xx RTM SDK v3.0.0 Example Projects". For monitoring Vector is being used, to see the traces of the communication.

Now I want to "modify" this example code to send out a diagnostic session Command.

I am not able to do this, i tried several things.
In the Example the 2 Buttons are used to enter deep sleep and wake up again.
I want to use these buttons to send out different diagnostic session commands.
(I think this is the easiest way to understand the diagnostic session)

A easy example on how to use these Lin commands would be great.

Or how do I have to modify the Code to send out these diagnostic session commands?

PS: Attached is the "Lin_master_s32k146" without any changes

Hi Raphael,

Please use function ld_send_message() to send an diagnostic command in bus and in LinStack component please set the maximum length of diagnostic message you want to use.

For the simple example, I have add this function in line 186 of attached file(main.c).

Best regards,

Hung.

Hello Hung,

thanks for your answer!

The values shown in your screenshot, were the default values for me so I did not have to change them. I used your recommended function, but it didn't work either. I expect changes in the schedule Table shown in my screenshot, but in there nothing changes. What did I miss?

Thanks for your time and effort,

Raphael

Hi Raphael,

Sorry, I am missing calling ld_init(LI0) function in the master task. It use to initial for transport layer.

Best regards,

Hung
