CCS/TMS320F28379D: drv8301 current noise

Part Number: TMS320F28379D
Other Parts Discussed in Thread: DRV8301

Tool/software: Code Composer Studio

I am working with mono_servo motor control example which is available in control suite,all is fine and the motor can spin following my command,but when I use 28379d and drv8301 to drive the motor, the current sampling has a lot of noise. At the same time, the motor emits abnormal noise. The speed of the motor is normal. The current loop and the speed loop track normally. And I found that the SPICLK has some effect on the noise.
