Hardware suggestion to work on TrustZone in Android

Note: This was originally posted on 29th August 2011 at http://forums.arm.com

Hi everybody,

For my MSc thesis I have to work on ARM TrustZone and the idea is to use it in Android OS (2.3+). I'm pretty new to this world but reading the forum and the documentation I understand that a dev board (or even a consumer device) powered by a TrustZone capable CPU (Cortex A15, A9, A8, A5 and ARM1176) is not enough to work on TrustZone since it would also requre to have a Protection Controller, an Address Space Controller and a TrustZone "aware" interrupt controller.
So, as fas as I can understand, I think that devices like Google Nexus S, which is powered by a Samsung Hummingbird Cortex-A8, will not guarantee that I can actually work with TrustZone.
- Does this mean I have to use a development board?
- Only development boards by ARM? I've never used a dev board but I see there are a lot of dev board manufacturers.
- Do you have any board to suggest me as candidate for the project? I must work on TrustZone but I also need to run Android.

Thank a lot for you help.
Bests,

Alberto

    Dear isogen74,

    Thank a lot for your reply. Is there any way to understand if the memory system the extra bus signaling? I've read lots of board datasheets from many manufacturers but nobody seems to underline this aspect (and even writing to the their tech support does not help). Talking about ARM dev board, is there anything specific to look for?

    Thank you so much.
