I followed the example on 
and was unsuccessful in my attempt to get System_printf to appear on my terminal (putty).
This is my code below from the main.c file:

I am currently using BLE stack 2.1.1 because the UART implementation linked on the website was not possible on the latest BLE stack 2.2. I am also using the TI RTOS that came with the BLE stack, which is TI RTOS 2.13.
Thanks for reading the post, any help on what to do from here will be appreciated.
