  • What is TrustZone for ARMv8-M?

    As a product manager for the Cortex-M33, I see this question pop up a lot. Below is my version of the answer.

    Characteristics of TrustZone technology

    • TrustZone is the security foundation for billions of ARM Cortex-A processor-based systems
    • TrustZone…

  • Which of the Cortex-M processors support TrustZone for ARMv8-M today?

    Another question that I see come up once in a while.

     

    Both the Cortex-M33 and the Cortex-M23 support TrustZone for ARMv8-M.

    Cortex-M23 is the smallest lowest power TrustZone Cortex processor from ARM.

    Cortex-M33 is a general purpose TrustZone processor…

  • What is the top level difference in features between Cortex-M23 and Cortex-M33?

    Both processors have TrustZone for ARMv8-M. The following table compares the other top level features.

     

     

    *Performance numbers are preliminary

  • Link to download gcc support for TrustZone for ARMv8-M

    * All GCC 6 features, plus latest mainline features:

  • [Cortex-M33 FVP]:SecureFault with SAU disable

    Hello,

    I am using Cortex-M33 FVP model to run the Keil RTX TrustZoneV8M RTOS example.
    Have also tried to experiment with the memory map configuration and the corresponding SAU region programming for NS/S patitioning and the behaviour is as expected.

    However…
