Dear all!
I'm a student. I want to buy a ARM Cortex-A9 board with ARM TrustZone implementation to develope my application.
At this time I don't need to use TrustZone, but I will use TrustZone for further developement.
Is there any Cortex-A9 boards that imlement TrustZone as an option?
On that board can I configure to enable or disable TrustZone feature?

Thanks and Best Regards

It kind of depends on what you mean by TrustZone support....

All Cortex-A9s support TrustZone. The question is whether the board's memory does anything useful with it . Then there is also the question of how much support you need for your work.

The only A9 board I know of which makes TrustZone development possible is the Versatile Express from ARM. There are probably others, but thats the one I've used in the past.

For your current design you have a lot of choice of boards, there are the Panda board, the Linaro Origen, and the ST-E Igloo, all will allow you to develop normal world application code either kernels or other. The issue with all of these boards, for your requirements, is this.

The above systems make use of the Secure world to ensure system security - ensure that the boot code is not tampered with and to ensure that the overall system cannot be compromised. This means they are not a good choice if you are wanting to move to secure development at a later stage. The developer only has access to the normal world where a system developer with full access to the Cortex-A9 core would expect their boot code to initialise the system and probably run their code as the legacy operation running in the secure world only.

As ttfn states above - if you want to develop your system from processor boot, you would need to buy a more featured system such as the ARM VE board.
