SWT0 S32K312 doens't work in Debug Mode

[atranzillo93]

Hi,

I'm using S32K312 EVB in Debug mode and SW resets when I try to enable SWT0 by setting WEN bit.

In my code, I leave the default configuration 0xFF00010A of CR register and when I try to set register WEN = 1, SW resets.
I expect that with CR[FRZ]= 1, using debug with watchodg enabled is possible.

I checked the bits:

• SWT0_DBG_DIS_CM7_0 that is 0
• SWT0_RST that is 1

Can you hel me?

I attached my code and registers configuration.

Kind regards,

Hi@atranzillo93

can you test the demo we provided in S32 DS, it seems works fine on myside.

[atranzillo93]

I found demo.

I try demo with my configuration and it doens't work if I set RIA = 1.

It works only with RIA = 0.

Why?

Thnks.

Hi@atranzillo93

According to the description in the data sheet, RIA is only used to respond to SWT's invalid access behavior.

I modified the RIA configuration in this example and it still works fine.

Now, it works.

Thank you.
