If you need to know exactly what failed, use the eJTAG port (its marked on the K3 board).

It is possible for a single transistor to fail (out of many millions), which may cause occasional transient glitches, or massive failure, or anywhere in between. The USB enumeration circuits may be intact, but something needed to boot from mmc may have a hardware failure. Some intermittent failures can be thermal sensitive as well, so one diagnostic method is to cool chips with a non-conductive spray chiller during testing.
