Without diving deep into the MCU versions used by both parts to determine if there are any differences - from a high level I would say as both are TMS570 parts in the same family you should be good to use the existing FreeRTOS demo as a base. The following link might then be helpful: https://www.freertos.org/porting-a-freertos-demo-to-different-hardware.html
Note also that the last time I looked TI’s HalCoGen tool would create FreeRTOS projects for you - so that might actually be you best route to getting up and running.
