And 3V0_N isn't working either.

FPGA is, at least, alive and running a blinky (but without the SERDES rails being functional).

And the main MCU responds over JTAG but I havent tried running code on it.

Sooo basically we have no real communications capabilities (1V2 is needed for baseT ethernet, GTX rails needed for SFP+) but most of the rest of the board seem alive.

3V0_N only powers one external trigger input so if that doesn't work it'll be annoying but not the end of the world.

Off to bed for now. Tomorrow, I think I'll pull the board again then see if maybe IR bottom preheat plus hot air on top is sufficient to get these DC-DC modules reworked.
