S32K344 A strange debug problem using the SEGGER Jlink debugger

[BrainLoader]

SEGGER Jlink debugger can program S32K344 project, but during debugging, the breakpoint is incorrectly positioned in the middle of the main program instead of at the beginning. Breakpoints added before the breakpoint will not be paused when the program runs there

 below is my debug check process.

Thanks for your reply!@Senlent 

Looks like I have the same configuration as you

But I find that it seems to have something to do with the running time,

Because when I add a delay, The breakpoint is positioned at a new location.

At the same time, I found this situation

It's going to refresh very quickly to look like this

In addition, the first debug after the code has been modified and recompiled always fails

as shown here

Hi@BrainLoader

can not see your question clearly.

the picture you provided is not very clear and can you send your project to me so i can reproduce your problem,

[BrainLoader]

Hi @Senlent ,

Thanks for your reply.Of course I will send you my project.

But I wonder if it's because of the debugger setup.

Because I used only modified the pin related in the example project.

And then these are my debugger configurations.

[Senlent]

There is no problem with your settings

It seems that you have modified the default version of J-LINK and GCC

[BrainLoader]

Thanks for your reply @Senlent.

The Jlink driver supplied with the S32DS seems to be too old and is causing errors at compile time 

[BrainLoader]

As an update

I updated my Jlink driver version to 7.86e and set it to the default path,

but the problem still occurs

[Senlent]

There is nothing wrong with your setup,
The difference is that the version of J-LINK is different,
