MCUXpresso SDK includes FreeRTOS Kernel and some examples based on it.
The last SDK for iMX8MPlus is SDK_MIMX8ML8xxxKZ v2.15 but it includes FreeRTOS Kernel
V10.5.1 (or it seems so, looking into some source files in /rtos/freertos/freertos-kernel/ folder).
But it's quite old (V10.5.1 - released on November 2022).
The latest release upstream is V11.1.0.
Is it possible scheduling the upgrade?
