RE: [fare@tunes.org: Re: [jornada] Jornada 820]

There is significant kernel dev work by some of the folks in HP Labs on the
Jornada 720 and our newer ARM devices, however the limited availability of
the 820's internally makes contributions by these folks difficult. The 820
was discontinued quite some time ago, but many are still in regular use by
their owners.

I have been working on a similar side project, but even internally at HP I
have difficulty gathering the information required to really get things
rolling. If there is some specific detail for which you are looking, I can
see if I can help you in getting it and making a contribution to the
community.

Thanks.

Dear Jornada users,
I've tried to check whether hpcboot did run the kernel,
after uncompressing it, and it looks like either it doesn't,
or the kernel dies *very* early:
indeed, I added code so as to hang while doing silly things
on the framebuffer, and the framebuffer was still.
How far have you people been with linux or bsd on jornada 820? Have you
actually run code in the kernel?
I've put all the information I have, together with my caricature of skeleton
of 820 support on
	ftp://Samaris.tunes.org/jornada820/
but please don't download big files from there.
PS: I've tried to contact HP about getting specs for the 820, but I don't
think I'm going to even reach anyone proficient enough to answer. On the
other hand, Olev Gusev has provided me lots of datasheets, so what would
remain to do would be guess where devices are mapped and how to tune them
well.
