  • Cortex-M23 FVP hard faults when using DS-5 Debugger

    Hi,

    I'm starting to explore this technology by running the TrustZone example application in Linux using GNU ARM Toolchain. This example is provided by a CMSIS software pack containing this example called "TrustZone for ARMv8-M No RTOS" which I was…

  • Why should we call secure function in handler mode?

    Why should we call secure function in handler mode? What is the design purpose for this?  As we know, none-secure side can also call secure function in thread mode.

  • DSP Filter Designer with Automatic code generation to CMSIS-DSP

    Did you know that there are 23 billion IoT embedded devices currently deployed around the world? This figure is expected to grow to a whopping 1 trillion devices by 2050!

    Less known, is that 80% of IoT devices are based around Arm’s Cortex-M microcontroller…

  • CMSIS: A success story

    When the first Arm Cortex-M3 devices came to market in 2004, it quickly became clear that a vendor-independent hardware abstraction layer was required to simplify software re-use and to reduce the learning curve for new software developers. The introduction…
