Hello Yu Long,
The new productions(include KE1x) will not support MQX and MQX lite .
For the kinetis chips , we will use FreeRTOS, it includes in the KSDK .
It is simple to used and free , about how to download and use it , please refer to this DOC:
Generating a downloadable MCUXpresso SDK v.2 package
Hope it helps
Have a great day,
Alice Yang
