S32K144: Device is secure. Erase to ensecure?

[tientv6]

Hello all,

Please help us.

I already flashed and debugged before. But today I got an issue "Device is secure. Erase to ensecure?"

I connected board via USB cable and Using OpenSDA interface to debug.

Thanks,

TienTran

Hello TienTran,

Have you been using the CSEc engine?

Was the MCU partitioned for CSEc at the time the MCU got secured?

Please refer to AN12130 Production Flash Programming Best Practices for S32K1xxMCUs

Section 3.2.5.2 Mass erase and CSEc considerations

Thank you,
