Energia for Cubesat OBC board

Hello,

I want to design and make Cubesat OBC(On board computer) using MSP 432 & energia for eash coding and RTOS.

But i am student and begginer.

if i design like schematic for MSP432-Lunchpad, could i use energia without any other processes?

if not, How can i use energia for my DIY board?

and I want to connect SRAM to MSP432 using SPI communcation and control SPI using energia

is it possible?

Could i use fully functionality of RTOS using energia ?

and if you any other advice, please let me know.

I'd appreciated if you reply these questions.

Thank you much.
