I am working on a project with the RP2350 at the university and I would like to know what is the real potential of this MCU in terms of TrustZone implementation. I have read the datasheet and I have been able to test its security features like Secure Boot and Encrypted binaries running in SRAM, but I have not found any starting point to get started with the TrustZone functionality of the ARM M33. I understand the concept of isolating the software in two spaces and how it implements the different IDAUs, but I'm a bit lost on how to start testing it (if it's currently possible).
That's why I wanted to ask the following questions:
-Is there any example project or documentation apart from the datasheet on how to implement TrustZone?
-Is it currently possible with the RP2350 and the Pico SDK? I understand that you have to flash two builds at the same time with the two isolated software in the secure and non-secure zones, is it possible with the Pico SDK?
Thanks for your time
