S32K148 FlexRAM Question

Hi

 

1.

I need to know the value of FlexRAM area when it is delivered from NXP (Virgin Device)

[0x14000000 ~ 0x1400ffff]

Currently, I don't have the s32k148 virgin device. So I can't check the value.

(Random(garbage) Value or 0 or 1?)

 

2.

I have develepment board.

And I did "partition command" to this EVB for csec use.

And after I did "erase all command" to this EVB, FlexRAM area value became 0xFF.

Is this value moved from FlexNVM?

 

These are related to mass production project.

I'm looking forward to reply.

 

Thanks

Best Regards

Phillip
