Summary
Both blocked M2 hardware milestones are done, plus the AD9361 sample-level datapath is validated on all three boards.
Root cause of the "board boots briefly then dies" mystery
The boards never died: multiple boards shared factory IP 192.168.1.10 on the wire, and two SD cards had been written with the same ethaddr (duplicate MAC -> switch MAC-table flapping). Diagnosed and fixed over the UART consoles (FT2232H channel B, 115200 - note: channel A/B mapping in FULL_PROJECT_CONTEXT sec. 13 is swapped).
