ARM FastModels for TrustZone Development

Earlence Fernandes
Note: This was originally posted on 22nd August 2013 at http://forums.arm.com

I am trying to learn about TrustZone and I've downloaded the FastModels 8.1 simulator.
The license I can obtain is only for the Cortex A8 Eval Board, and The ref manual for FastModels implies that
no trust zone is built in.

Which fast model I can use to experiment with trust zone?
How do I get the required evaluation license? I am a student and have a .edu email address?
Anyone else with similar experience? My first step is to boot a linux kernel in secure world.

    That makes sense.

    Are you aware of any of the Fast Models that include a TZC component that supports dynamic mapping of memory to secure/normal worlds?

    I've been looking at the Cortex A9x4 VE board, and it doesn't seem to have the TZPC (BP147) component as well. Does this mean that all secure RAM/normal RAM
    mappings are final and static and "written in hardware" ?

    Earlence,

    That platform

    You may wish to look into
    TZSwitch.lisa - that supports switching access between 2 ports based on external signal. This is part of all VE daughter board and will be part of the A9 VE Model.
    TZC_400 - that supports more complex mapping and switching with registers - I suspect this is the one you are looking for.

    If neither of these do what is needed, you will have to write your own.

    regards and best wishes
