• Regarding ARMv8M processor Cortex-M23

    Hello,

    I am looking for a development board and software development kit with ARMv8M processors Cortex-M23.

    I need to prototype trusted applications in c/c++ programming language for my research work.

     I am expecting availability of development libraries along…
