Hi all,

I am currently trying out TF-M together with Zephyr and therefore ported it to the Nucleo-U575ZI-Q evaluation board. I started to struggle when trying to implement an example for a custom Secure Partition (SP) which should access peripherals.

I recognized, that the `target_cfg.*` throughout different vendors follow different design principles. E.g. for Nordic controllers an example is given with their nordic-sdk on how to implement peripheral access for a SP (https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.0.0/nrf/samples/tfm/tfm_secure_peripheral/README.html). For ST devices I tried to transfer this, however, where unsuccessful so far as for the ST microcontrollers the peripheral definitions are missing, and things are just different.

Is there any example for ST controllers on how to make specific peripherals only accessible through SPE? Is this currently supported for ST devices?

And another question, as the Embedded Open Source Summit arises, is TF-M represented somewhere on conferences?

Kind Regards
