RE: Flashboard for a 720

I ported blob to the '720 some long time ago.  It has full support for
programming flashboards (at least of the variety we were building in
HPL) and for booting linux.

I tried disassembly (some other maybe too), but no success - I do not
have a really good debugger, I only had a disassembled code, which is
not enought.

I tried to contact HP engineers, but the WHP2000 is dead for several
years and nobody is willing to spend time (=money) on investigating how
it was (pretty understandable), also it's maybe some kind of NDA with
MS.

As of flashbootldr: The guys from HP CRL wrote themselfs the bootldr for
flashboards, as experimental project to implement Linux on jornada. As
CRL is closed now, I am almost sure there is nobody with time to develop
anything for 6 years old device. The only stuff that is available for us
is the one on the handhelds.org, which is from mid-canceled linux
implementation project. I am glad that the outcome of this project was
linux running on J720, but we can hardly expect any more help from HP.
