ZMK remains after board is powered down ?

[gg_NXP_user]

Hello all,

In the Security Reference Manual (IMX6DQ6SDLSRM_RevD.pdf), it is specified that the ZMK key is zeroized after a "security violation".

Is the ZMK key also zeroized after the main power off of the card?

Is there a way to keep the ZMK key in the SNVS_LP part, outside of using a battery?

Regards

Do not catch what your first question is. 

Is there a way to keep the ZMK key in the SNVS_LP part, outside of using a battery?

-> As I know, there is no such way. 

Best regards
