Lock up event on Flash partitioning

[sabeelmohamedkh]

Hi

In reference on S32K148 controller, we are trying to partition the flash area into 1.5MB of code flash and remaining 512Kk region as a FlexNvm, After execution the programming sequence to program FlexNvm , we are obtaining Resets due to LOCKUP event.

Could you please share on the reasons for the same.

Hi,

Do you launch the program partition command from RAM?

Hi Daniel.

Your response triggered my another question.

Is the partitioning command a procedure which has to be execute through executable code located in RAM?

Shall I have to perform an overlay?

I'm asking so because in the device's RM (Rev. 6, 12/2017) I noticed this recommendation in § "35.5.11.14 Program Partition command" which states :

"...

Program Partition command must not be launched from flash memory, since flash memory resources are not accessible during Program Partition command execution.

..."
