OMAP-L137 SPI Clock

Hi,

I captured the SPI clock signal from my OMAP-L137EVM. I found that there is a small spike at the very beginning of the SPI clock. (yellow dot) This spike has caused problems to my SPI data. How to clear this tiny little spike? anyone?

Does that spike occur at the start of every transfer, or does it just happen the first time? Does the spike correspond to turning on the peripheral or changing the pinmux?
