Linux on the Sharp Mobilion PRO PV5000A?

Linux on the Sharp Mobilion PRO PV5000A?

Hi All,

I've recently acquired a new toy, a Sharp PDA.  From what I've read on
the NetBSD/hpcmips website, and other places, it's based around a
Toshiba TX3922 129MHz CPU and has 32MB RAM.

I've done some research, and it looks like this machine may, be a cousin
of the Philips Velo.  I'm yet to pull mine apart (which I'll have to do
at some point, to fix a dickey power socket), so I can't be sure what
hardware mine has.

Anyway, what I was going to ask, is has anyone tried Linux or NetBSD on
this system?  If someone's already started work on porting, then I'd
like to assist where I can, no point in two of us duplicating efforts :-).

I've put some stuff up on the wiki[1], about what I know on the device.
 I'll possibly look into getting some sort of WinCE/MIPS dev environment
set up, so that I can compile apps to explore the hardware on the
device, but I'd be interested to hear if anyone has attempted a port to
such a device.

Regards,

This is old information about TX3922.

I don't know that Telios and PV5000A are the same.

I'm fairly sure they aren't.  If I remember correctly, the companion
chip PLUM2 was only used in the Telios.

Well... I actually pulled mine apart tonight.
http://www.linux-mips.org/wiki/Sharp_Mobilion_Pro_PV5000A#A_look_inside

My primary objective was to fix a wobbly power socket... but I also took
the time to take snaps of the board & its chips.  In putting the unit
back together again though, it seems I now have some spare screws...
oddly enough, WinCE seems to boot & run ever so slightly faster.

You could say I've made it more efficient by removing parts -- but I
don't think screws count :-)

I'll have to google some of the ICs... I actually thought this would be
using the Philips Poseidon SoC, but no, there's not a single chip with
"Philips" written on it anywhere.  It's mostly Toshiba circuitry -- one
will be responsible for I/O, I know that much. :-)
