Key Import HSE API

ale_di_vi — Wed, 07 Jun 2023 13:22:33 GMT

Hi, I have a question regarding cryptographic keys stored inside the NVM of HSE_B module.

Is it possible to update these keys from the context of the application running on host microcontroller using "Key import" API of the HSE (chapter 7.2.3 of the HSE_B Firmware Reference Manual Rev. 2.1 11/2022)?

In case it can be useful, the microcontroller used is MWCT2015S.

Thank you in advance

Hi @ale_di_vi

Yes, the keys can be updated by application running on the microcontroller. You can take a look at HSE_DEMOAPP for details.

Regards,

Lukas
