I am using imx6UL ,in my design i have a SD card slot connected over usdhc2. Functionally the SD card is working fine but when I am probing the SD card data line and Clock line there is a overshoot up to 3.8 V for 2ns and undershoot of 1V for 2ns in Data line and in clock signal waveform is swinging between -1V to 4V.
What could be the reason. Will it be harmful for the processor.
Wave forms attached for your reference.
