[jornada] Re: de-brick

In case this is useful, I have put the source (and a very brief
Readme) for the jtag programming tool that I have been using
for Jornada56x devices at:
    ftp://salsa.lcs.mit.edu/pub/jca/jflash.tgz

It requires a cable which is relatively easy to wire and some
way of connecting to the Jtag pads on the back of the 56x.
I have been using a custom milled block of nylon that uses pogo pins
(push pins) to connect to the test points.

I don't recommend using this tool, as you will definitely
erase your flash, perhaps making it unusable (until you
re-program it correctly!). I did want to make the source
and wiring information available for those among us who
are already the proud owners of expensive bricks in
hope that they can make them functional again.

Have fun,
jca
