Intefacing EK-TM4C123GXL with DRV8305 Evaluation Board

We are facing some issues while interfacing DRV8305 with EK-TM4C123GXL board.

​We have interfaced this with SPI on ​EK-TM4C123GXL board with single PWM operation mode of DRV8305. but we are not getting the desired output. The BLDC Motor is not rotating.

I am attaching the code herewith:
