Problems when flashing a program with IAR compiler on the s32k116 board

[David_Estevez]

I am using a project for an S32K116 microcontroller with the IAR Toolchain for ARM -8.x compiler.

I am flashing the program with a PE Micro Multilink. The program works in debug mode, but when I disconnect the PE Micro Multilink, power off and then power on the microcontroller, the program stops working. Could you help me with this problem?

Kind regards.

Hi

This may be caused by the lack of START_FROM_FLASH in the assembly preprocessor. Please refer to the previous discussion: S32K118 runs with debugger, but not without

Since I didn't install the IAR Toolchain for ARM -8.x compiler, I found a picture on the Internet: Assembler -> Preprocessor -> Defined symbols-> START_FROM_FLASH 

Best Regards,
Robin

Hi Robin,
I have made that change just as you have shown.

But I am still facing the same problem.

Let's check where the program went wrong by Attach to Running Target.

What is the value of SR0 you see?

[David_Estevez]

Hi again,

This is the SR0 value.

[Robin_Shen]

It looks the same as the picture I replied to you last time. This is because the ECC error is caused by not executing the #ifdef START_FROM_FLASH code that initializes the ECC RAM.

I have not finished the installation of IAR. If you find through debugging that the initialization ECC RAM code is not executed, then we should check why the definition of START_FROM_FLASH is not working.

Please add START_FROM_FLASH to IAR Assembler->Preprocessor->Defined symbols 

As I mentioned before, after adding START_FROM_FLASH the S32K116EVB can work normally after power on.

Thank you for the solution!
