S32K116 with IAR doesn't start without debugger

Hello,

I'm using an S32K116 with an application compiled with IAR.

I'm using Segger J-Link debugger.

I can flash the SW using J-Link but when I reset the board without the debugger connected, the SW will not start.

I used IAR to "attahced to running target and found that the SW is stuck in HardFault_Handler from function init_data_bss at step /* Copy initialized data from ROM to RAM */.

What are the steps to investigate on this issue?

Thank you.

With JLink debugger and JFlash v6.60b software I can start manually the application by using Target->Manual Programing->Start Application.

It gives me the following log:

Hello,

Issue is fixed after adding START_FROM_FLASH in assembly preprocessor.

Thank you for posting this, had the same problem with an S32K118 using S32 design studio... Can't believe the default project settings are this bad!
