I am using the STM32H5F5 and plan to implement the Secure Manager. I would appreciate clarification on the following questions:
Can the user application key be provisioned to the OBKey area during Secure Manager installation?
After the Secure Manager is installed, can the user application write a key to the OBKey area?
How can an application—secure or non-secure—read a provisioned OBKey?
Hello,
Concerning Secure Manager for H5 you have a large panel of wiki articles available here:
https://wiki.st.com/stm32mcu/wiki/Category:How_to_start_with_Secure_Manager_on_STM32H5
To briefly answer your questions:
1- Yes during the provisioning/installation flow OBKs are provisioned.
You can see an example of provisioning in this wiki article : https://wiki.st.com/stm32mcu/wiki/Security:How_to_start_with_Secure_Manager_default_configuration_on_STM32H5
2- After the Secure Manager is installed, product is in TZ-Closed with secure resources protected.
3- Secure application can use OBKs
