The normal USB PHY chip we get is out of stock and the only one we can get is the USB3370B-EZK-TR. Does the processor support this USB chip?
on our EVBs, either USB83340 or USB3340 are used. The only difference between USB3340 and USB3370 is fixed reference clock frequency on USB3370 (the other ones support more frequencies). So, I can't see problem here from microcontroller's point of view.
