Application runs in Debug mode but not in Run mode / Not retained after power cycle

Hello,

I am working with S32 Design Studio for ARM and the S32K144 EVB for application development.

I am able to debug the project without any issues using the debugger in S32 Design Studio. However, when I try to run the application normally, I get an error popup and the program does not execute as expected.

Also, after power cycling the board, the program does not start automatically. It seems that the code is only running during the debug session and is not being stored in the internal flash memory.

I would like clarification on the following points:

- Why the application works correctly in debug mode but fails in run mode
- Whether any additional configuration is needed to program the code into internal flash
- If any linker or debugger settings must be changed
- Whether S32 Design Studio can be used alone for flashing or if an external flash programmer is required
- The correct method to ensure the firmware runs after reset or power cycling

Please suggest the correct configuration and programming procedure.

Thank you.

Hi @padmaja 

Your issue seems very similar to the one discussed in the thread: Flashing Code on S32K144 EVB – Debug Works but Run Causes Error. It may be helpful to review the suggestions shared there as well.
