That likely won't reset the firmware as the firmware's storage is
non-volatile.  You'd either have to externally flash it, or go into the
firmware itself to reset it.

There's a change on the Turbots that changes J7 to act as a firmware
reset on power on, but that requires the more recent firmware (0.84 has
it for sure, I'd have to go back and check if 0.83 does or not), as well
as a Turbot.

So does the board do anything?  Are you seeing anything on serial at
all?  Does D2 come on or does it bounce (or not come on at all)?

So likely not the power supply's fault ;-)
