  • Double RTOS kernel running on Cortex-M33 (Trustzone)

    Hi all,

    it would be possible to run two different RTOS kernels on a single core (Cortex-M33) using Trustzone?

    For example, let's suppose I want two full RTOS instances (e.g. FreeRTOS), one running in secure zone and other running in non secure zone.
