Is it possible to run FreeRTOS, or any other RTOS on Kinetis K28F MCU? I bought a few FRDM-K28F boards, installed MCUXpresso and the SDK for K28F. But I don't see any example code or demos for FreeRTOS or any RTOS, as implied in the "Getting Started Guide". Can anyone from NXP, or someone with experience, confirm whether I can use FreeRTSO on K28F, or do I have to select another MCU, e.g. LPC or iMX.RT series?
