CCS/EK-TM4C123GXL: TivaWare SPI example not working

Part Number: EK-TM4C123GXL

Tool/software: Code Composer Studio

Hello all,

I'm trying to learn SPI communication, and I think the best place to start is with the examples provided in the TivaWare Library (already did this to learn I2C and successfully applied to a PCF8574AP). 

Problem is, I am not receiving the expected output. I'm using the spi_master.c example. Not sure on what I'm doing wrong...
