no output from uboot at all. no output of any kind.
Assuming it isn't hardware death the only option I can see is re-flashing.
i haven't cracked the case. does anyone know if there's
a jtag port at all in a sheevaplug?
Even if there's no ready-to-use JTAG port on the board on the PCB there
sure will be a site where you can add a pin header or box header (requires
some soldering). From there it should be straight forward. Identify the
site (ARM JTAG comes in 10- and 20-pin varieties)and pinout, then connect
to your JTAG board/box.
I have tried that with a bricked Patriot NAS that used a Marvell 88F5182.
The device didn't have a serial port nor JTAG but both facilities had been
thought of on the PCB. Now it has serial console and can be un-bricked at
will.
P.S. Other two replies show Marvell has been more considerate than Patriot.

yes. that's how i set it up to pxe from the auth server.
What's the output from uBoot, if any? As a last resort, tried
re-flashing it over JTAG?
