CCS/LAUNCHXL2-TMS57012: Setting up SCI/UART comms for debugging via terminal

Part Number: LAUNCHXL2-TMS57012
Other Parts Discussed in Thread: HALCOGEN

Tool/software: Code Composer Studio

Hello TI forums, 

I'm a complete newbie to Launchpad development, but have successfully created a simple "hello world" printing program to the terminal using this tutorial on the XL2-TMS570LC43x: .www.youtube.com/watch

I'm now trying to do the same thing on the XL2-TMS570LS1224, and am not picking anything up via the terminal. I've noticed the LS12 boards have a different SCI pin layout, so I'm assuming my setup in HCG is incorrect for the LS12. 

On the LC43, I have the GIO driver, SCI drivers, the SCI1 driver, and the SPI5 driver enabled. On the LS12, I have the GIO driver, SCI driver, and SCI2 driver enabled. 

I've been trying to SCIsend the hello world message to "sciREG2", as the register "sciREG1", which I use on the LC43, is undefined, presumably because there was no option to enable it in HCG. 

I know how to access the terminal for serial comms (COM port, Baud etc), so I am certain that's not issue.

Please let me know if I need to provide any more information, as this is completely new to me. 

Thanks in advance!
