Hi NXP,
in S32K3, doc says the ADKP saved in NVM in origin or with uid diversified. but in demo example, the function HSE_ProgramAdkp() just use HSE_APP_DEBUG_KEY_ATTR_ID to write the key.
my question is , what does ADKP_MASTER defined and how to config it?
Solved! Go to Solution.
Hi @victory
ADKP_MASTER selects the method to provisioning ADKP: diversified with the device’s UID or written “as is” in secure NVM. Refer to sections 2.6.1.4.4 (Provisioning a device-dependent ADKP) and 2.6.1.4.5 (Secure ADKP Provisioning) of the HSE_B Firmware Reference Manual, Rev. 2.3.
If you are loking to configure ADKP with UID diversification option, you must set ADKP_MASTER before programming ADKP (HSE_APP_DEBUG_KEY_ATTR_ID). TS32K3 will automatically perform the UID diversification operation when programming ADKP.
