Not able to do Mass Erase using ULINK2 debugger

Hello Team,

I deactivated SWD interface of S32K116 MCU by configuring FSEC register. During this process, I have enabled Mass erase for doing further development work but after 3-4 times interface is not able to do Mass erase. Can you please support how to unlock the device.

Please find snapshots for your reference.

Hi prabhatg44,

Please try to use the P&E Recovery Utility described in Recovering Cortex-M Microcontroller with a Power Glitch.

Notice that a debug probe from PEMICRO is needed.(can not use ULINK2 debugger or J-Link debugger) If you are using S32K116EVB, then the onboard OpenSDA can be used.

Best Regards,
Robin
