Hi @ale_di_vi
- How the system attribute to manage this state can be triggered? Can it be done via UDS?
[Lukas] If HSE firmware is installed, the life cycle can be advanced by HSE system attribute management services (HSE_SRV_ID_SET_ATTR and HSE_SECURE_LIFECYCLE_ATTR_ID). It’s up to user to trigger this service by software. It doesn’t matter what kind of protocol or communication interface is used to trigger this service.
- I see that advancing to PRE_FA and FA can only be done by NXP, how? What is the process to advance the status and what type of test features are "unlocked" in those states?
[Lukas] As mentioned, it can be done only by NXP for testing in NXP facility, so we do not share more details.
- Is it possible to have internal test analysis of pieces coming from field mantaining the LC state to IN_FIELD?
[Lukas] No, it’s necessary to advance the LC at least to PRE_FA because internal test features are not available in IN_FIELD LC.
Regards,
Lukas
