I am afraid there isn’t any official S12Z FreeRTOS support om NXP site.
The FreeRTOS implementation usually requires at least 16kB of RAM – of course it strongly depends on the final application too. I think it could be possible to use the largest S12Z MCU – S12ZVC256 with 32k RAM but we have not the SW example.
I want to recommend you the great source of useful information related to RTOS:
