ADKP Password Change

[jeongwoo]

Hello NXP,
We are using the S32K312 board.
We would like to know whether it is possible to change (or reset) the previously configured ADKP after Configuration Lock when the Life-Cycle is in the In-Field state.

Additionally, we would like to know whether it is possible to change the Life-Cycle from IN_FIELD to CUST_DEL.

Hi

Section 4.2.1 Configurable HSE system attributes of RM758227-RM00286 HSE-B Firmware Reference Manual - V2.7(2.7).pdf:
A set of programmable HSE system attributes within the secure NVM can be provisioned by the host via HSE administration services. Some of these attributes, once set, cannot be updated.

ADKP is listed in Table 16. One-time configurable HSE system attributes

Therefore, it is impossible to update ADKP anymore.

Page 17/299 states:

An LC transition is always one way. Reverting to a previous LC state is never possible.

Best Regards,
Robin
