lifecycle transition in s32k3

[HyunungPark1]

I know that the transition from CUST_DEL to OEM_PROD or IN_FIELD is only possible if the application debug key / password (ADKP) is provisioned as the specification.

the current lifecycle is OEM_PROD debug key / password (ADKP) is provisioned.

Is it possible to change OEM_PROD to IN_FIELD if the application debug key / password (ADKP) is provisioned?

Hi @HyunungPark1 

In section 32.5.2 (Address LC configuration word) of the S32K3xx Reference Manual, Rev. 8 states that "To advance LC, you must program a valid 32-bit wide value at an address given in IVT at an address offset of 24h."

Also, "The chip provides an LC mechanism for an irreversible progression of restrictions to access the chip's security-related content. You cannot reverse the chip's LC, so it is only possible to mature the chip. SBAF advances the chip through the LC:

• CUST_DEL --> OEM_PROD or IN_FIELD
• OEM_PROD --> IN_FIELD"
