New Example for arch_printf??

I am struggling with the UART interface even after reading thru the forum posts. I am starting with DA14580_DSPS_3.150.2 and would like to integrate the arch_printf function so that I can send debug commands to the TeraTerm output console. My current code version gets stuck here:

while(!uart2_thre_getf() || !uart2_temt_getf()); in uart2.c.

Any help would be appreciated.
