Re: [jornada] 568 bricked

Vincent,

It sounds like one (or more) of the following might be the source
of the problem:
    1) wires on the jtag interface are not making good contact
    2) all the batteries (main and backup) have not been removed
    3) power cycle the jornada (waiting 2-3 seconds after turning
        off) before each couple of attempts. (This causes the processor to
        reset into a known state.)
    4) there is a small chance that there is something odd with
        the bios settings for the printer port (although this should be
        fixed in the version of software at:
            ftp://handhelds.org/pub/hp/jornada/jflash.tgz
        )
Please let me know if you still have problems and I can
reflash your Jornada with a programming jig that I have
here (I finally got my setup working again after giving away
several sets of probes to other groups inside HP).

Thanks
jca
