    CYUSB3014 boot issue



              I used CYUSB3014 in my design, but  it fails to boot from USB. When debugging, I found that the voltage of the DP pin is not pulled up to 3.3V, but about 0.6V? The crystal oscillator does not vibrate when it is powered on, but it starts to vibrate after the chip reset. I used both VBUS and VBATT to power the USB module. The VBATT voltage is 5V. Is there any problem with this design?

              This question has troubled me for a long time, looking forward to any reply!
