S32K LifeCycle

[vurtual]

Regarding S32K312, I has installed the HSE Firmware in the device. My code is to call the HSE_AdvanceLifecycle function to evolve LC to OEM_PROD. However, one of the chips in our factory has evolved to IN_FIELD. I would like to ask, apart from using the function evolution LC normally, are there any other ways to achieve this?

My code:

volatile hseAttrSecureLifecycle_t programLC = HSE_LC_OEM_PROD;

HSE_AdvanceLifecycle(programLC);

That's interesting, however LifeCycle cannot be changed to IN_FIELD by any kind of error as interrupted flash programming by reset and so as this would lead in LC_ERR fault (see DCMROD3 register).

I would expect certain SW misconfiguration.

Could you give an example of SW misconfiguration?
