Is it configured to use a serial console? Tried checking the output there?
What's the output from uBoot, if any? As a last resort, tried re-flashing
it over JTAG?

yes.  that's how i set it up to pxe from the auth server.

no output from uboot at all.  no output of any kind.

i haven't cracked the case.  does anyone know if there's
a jtag port at all in a sheevaplug?

Yes there is :-). It is another endpoint in the usb. I would try going at it with openocd. My jtag driver doesn't do reflashing yet.

Be aware that sometimes if the jtag isn't used early enough after
booting it will not respond.
Though, if there is not light in the ethernet, it sounds like it is fried...

both lights are solid on and it is not very warm.

There is. I've used it to debug Linux boots with openocd.
The FTDI chip at the the USB-device connector should show you two serial ports.
One for the console, and the other for the JTAG.

Another possibility -- the omap "on chip" firmware will use SD-based
uboot image if it finds it, instead of flash. If the plug plays by the
same rules, you might be able to put a known-good u-boot on an SD and
use that image.

Marvell chips lack that. TI and Samsung were a tad more thoughtful.

Assuming it isn't hardware death the only option I can see is re-flashing.

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.

After one year of working, in mine some power supply capacitors blew up.
I replaced them, and it worked again.
After two months, more old capacitors of the power supply blew up.

When I had all replaced, it worked again, and I've not had any problem since
then. It even stays less warm than before.

Regards,
Lluï¿½s.
