How to set MCU security for s32k144 in keil muvision without using startup file?

I am working with S32k144 board and created own scatter file and vector files for handling the faults. I am not using the auto generated startup.s file. In Startup.s file we can change the Flash config fields like backdoor key, protection registers and the MCU security byte FSEC.

How can we do the same when we are using own scatter file and boot vector files?

where i need to add the FCF? In which file i need to change the settings

Hi @charan257 

well, this is a question rather for Keil support:

From S32K144 point of view, it is just necessary to force a constant data at address 0x400.

Regards,

Lukas
