Dear NXP:

 

             We designed our LPC5460X board refer to NXP EVB, it works good at first, but after hot swapping and hot insertion  several times, the CHIP USB1_AVDDTX3V3 and USB1_AVDDC3V3 are short circuit to GND, do you know what operation could cause this problem ? (If don't supply USB1_AVDDTX and USB1_AVDDC3V3, the MCU software still can run)

 

Best Regards

Yan
