Application Not Working After Power Reset on My System (Works Fine on Other PCs)

[Juns]

Hello,
I am currently a trainee practicing with the S32K118 microcontroller.

I have installed versions 2.2 and 3.5 of the S32DS Tool on a Windows 11 system. For the toolchain, I am using GCC 6.3 for Arm 32-bit Bare-Metal, and the SDK version is 4.0.1.

During debugging, I noticed that the standalone mode does not work in the Semihost Console. To address this, I selected the P&E interface, configured the debugging type, and performed the flashing process.

However, after removing the debug-related code and powering off/on the application, it does not operate correctly.

• Key Observations:
  • On other computers, the same logic works perfectly.
  • On my system, even though both the clock configuration and pin initialization parts pass successfully (verified using a Status variable), the application does not function as expected when a power reset (off/on) is performed.

Could you help identify the reason why it works fine on other systems but fails on mine? Any guidance would be appreciated!

i don't have Gernerate Code folder

Hello @Juns.

I suggest to checking  for any differences between your computer and Design Studio setups and the others where everything works as expected. Also, on the computers where the logic works, the application also function after a power reset?

I will be waiting for your response.

Thank you again for your response! And I found another issue—there's no separate "Generate Code" folder, and since I'm using the UJA chip, when I go into that folder, there are no files. So I wonder if this is the problem. Please check it! I posted the full response in the thread since I can't upload the images as two separate answers. Please take a look!

hello, @RomanVR

Thanks for your quick response

As you mentioned, I haven't been able to verify the setup portion, but I’m currently working with the S32K118, and I’m essentially clone-coding the fully implemented logic. I have set up all the components, peripherals, etc., identically, and I’ve configured the flash memory in the same way. However, in my case, everything works correctly as long as I don’t disconnect the debugger cable and power. But when I perform a POR (Power on Reset), it doesn’t work on the client I built (as if the flashing process hadn’t been done).

Also, during debugging, does the flashing process only occur if I select the P&E Interface and then terminate? Or should it work if I run the main file during debugging and then terminate?

In my case, the flashing process does not work properly unless I select the P&E Interface. Please refer to the photo below.

Hi @Juns 

I tested the "lpit_periodic_interrupt_s32k118" example on the S32K118EVB-Q048 to try to recreate the issue you mentioned.  I found that  when a debug session is active, the code works as expected. However once the session is terminated, the MCU stays in a "freeze" state and the code stops working, although if the power supply is disconnected and connected again, the code runs properly without having an active debug session. Have you observed this behavior if the supply is disconnected and connected again?

About the flashing process, if you can successfully open a debug session, this means that the code is being also flashed to the MCU, therefore the code should run as expected by just being able to debug the code.

Finally, about the "Generate Code" folder, this is only created in S32DS 2.2 since it uses Processor Expert to load the configuration files of the drivers used in the project, meanwhile S32DS 3.5 uses Configuration Tools, hence the difference between the generated files among the versions involved.

Please let me know if this is useful.
