    [color=#222222][font=arial, helvetica, sans-serif][size=2]Some of the development platforms from ARM might be useful, as they tend to be less restrictive than a real platform, but they are usually quite expensive. The other option is a software model of a system which can run Linux, etc. ARM have some quite good system models that run at 150MHz simulated speed or so, which are good for development. Drop ARM support an email, and mention you are from a university.[/size][/font][/color]

    Thanks for your reply.

    I will look at the framework you mention.

    I dropped them an e-mail and I'm talking to them about it. I will write here when/if I get some idea of how to use TrustZone in a non-commercial environment - aka, with no monetary agreements with a vendor.


    Best,
