Build MMC v2.1 from tom using default settings in AVR studio 6.1 and flash.
Payload power comes on, MMC messages look ok but can't ping at jumper-based address.
Module is
AMC13XG #34, IP addr should be 192.168.1.186. Charlie is investigating.
Board in slot 3 works; board in slot 4 doesn't. Here is the "show_sensorinfo" output
from the MCH:

Looking at JTAG signals on S/N 0x20.
Now moving the T2 board from S/N 19 to S/N 0x21 for testing. Programming works, as expected.
JTAG signals look quantitatively different,
but the details would require days with a logic analyzer.

Chris changed the chip on S/N 0x20. Didn't help.

Mysteries with MMCs on new T2 boards. Chips are marked 3A1512 but ID as 3A0512 according to Wu.
Chip marking:
32UC3A1512-U
1114 D5CQ5.1
