TF-M Support

Hi Team
Greetings

We are working on an STM Microcontroller using TFM architecture with the TFM application and TFM SBSFU for Thales Payment Project.
We are in contact with ST for our queries regarding some of the requirement implementation and still haven't received a clear picture.
Kindly assist us in achieving the following requirement.

1. I need to access a secure module from the non secure area of the application as per the TFM architecture. Could you please suggest a step by step method to access the secure area.

2. how can i add a peripheral(example ADC) in the secure zone of the TFM project.

3. i want to add a crypto module that I'm developing into the secure area and access from the non secure world.

Could you please suggest some insight into how the requirements can be achieved using TFM on STM32U5

Thanks in advance for your understanding

Regards

Philip
