Starterware/SIMPLELINK-MSP432-SDK: MSP432 develop

Tool/software: Starterware

Hi， 

      Now I am using the MSP432 launchpad.  But I find it difficult to start with the demo in simplelink SDK while  using rtos. I mean the examples provided is too simple to use. For example there is no uart  demo combined with DMA. When dubugging interrupts, I can find msp432_startup_ccs.c no where, which is included in project files in no rtos condition. How to achieve my interrupt with rtos?

 I am confused that  the SDK well supports the development of MSP432 using no rtos, but not very friendly to rtos customers. Since MSP432 is based on M4 core, I think abstract api drivers should be supported better like STM32 series. 

Are there any documents explain my confuse? I need help.

Than you!
