hpcboot

Re: SE GC83 GPRS card: pppd problem

Has anyone had any success installing 2.x or 3.0 on a Psion Teklogix
NetBook Pro? This is a 400MHz XScale PXA-255 processor with 128MBs of
RAM. The one thing I found odd was that, unlike the hpcmips port,
HPCBoot.exe is nowhere to be found in the hpcarm files. It is
mentioned many times.

I have a partitionable 5GB hardcard and a 2GB CF card which I can
partition in Linux if need be. I just want to put a traditional
install of NetBSD on this thing. Any help is appreciated.

Do:
uudecode -p hpcboot.exe.uue > hpcboot.exe

in src/sys/arch/hpc/stand/binary/ARM

What system ASIC do they use.  The one in Psion7 was proprietary, with
no documentation available publicly.  They had an arrangement with the
Linux folks to make the docs available to them.  If NetBook Pro uses
the same ASIC, we need the docs made available.

It is in the cvs.  It was not installed into the release dir untill
recently.  You can get it from:

http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/hpc/stand/binary/ARM/hpcboot.exe.uue?rev=1.5&content-type=text/x-cvsweb-markup

and uudecode.

It's a nice machine (I used to have Psion7 and the design and general
feel of the machine was *very* nice, and NetBook Pro has the same
design).  But it's 900 quids excluding VAT (1055 with VAT) from
eXpansys - which is kinda prohibitive pricing for a hobby use. :)

It would be nice to support it, but we need someone with 1) hardware,
2) willing to hack on it.  (And then there's may be that documentation
problem).

Thanks.

I realized that immediately after sending it. GMail doesn't make the
subject field editable until you click a link. Just me not paying
attention :) Sorry all!

I'm not positive of this, but I'm sure the P7 was the old ARM7 255MHz
processor, where the nBPro is an XScale PXA-255. I'm almost positive
that these use different North and South bridges, so it would
necessarily be a different ASIC. The one thing I do know is that this
unit has something called BooSt, which appears to be a command line
environment for the Flash ROM.

I agree on all counts. I was lucky to receive mine as a press kit. The
one thing is that I am very, VERY tired of Windows CE .NET 4.2. It is
slow, incompatible, and there is little software available since
Microsoft nigh abandoned it. The sooner I can get NetBSD on it, the
happier I will be. To that end, I'd be pleased to offer up my netBook
Pro to the hacking gods.

trimming RAM usage

Hi all,

I guess this may not be HPCARM-specific, so feel free to tell me off for that.
I have been searching for info on lowering memory usage on my J720,
running NetBSD 3.0-RELEASE.
I didn't find any given page, but googling and a bit of embedded Linux
experience helped. My aim is to be able to run the meta-port of
matchbox-0.9.5 (wm, panel, etc) with dillo together and not having any
app killed for want of RAM.
I do have NFS-Swap, but it's neither fast nor always available.

So far these are the points that I figured could be acted upon:

1. recompile the kernel, remove unnecessary drivers and features.
      My kernel is 2.6 MB because I've had to include APM + IPSec, and
uses 4236K.
      It is 2.2MB without. Anyone managed to trim it further?

2. replace the built-in SSH with dropbear? Anyone done that?

3. is there a low-memory alternative shell, that uses less RAM than
ksh or bash? (doubt it but thought I'd ask, I surely didn't find one
that claimed to)

4. only have one or two gettys

5. don't use xdm (uses 1.2-1.5MB)

6. if using PF as a firewall, disable pflogd (~3MB!)

7. any recommendation for sysctl vm tuning?
    my sysctl.conf has got this:
     vm.anonmin=5
     vm.execmin=5
     vm.filemin=0
     vm.anonmax=95
     vm.execmax=10
     vm.filemax=5
     vm.bufcache=5
   But I feel something is wrong. It works better than the default though.

8. use mount_mfs sparingly :)

9. avoid using dhclient (almost 1MB)

Anything else that I have overlooked?

Thanks,

M.

tpctl inacurrate or failing?

Hi all

I'm running into problem with tpctl on my 720; the way they look I
shouldn't be the only one, but here goes:

- I ran tpctl from the console as root
- made sure /etc/tpctl.dat was created and filled in
- added tpctl=YES to rc.conf
- /etc/rc.d/tpctl start -> "calibrating touchscreen..."
- so I launch xdm to check calibration

And no matter what I do, there is a skew. On most of the screen, the
pointer is off to the right from the stylus. The distance increases
the further towards the right you go, and a few other inaccuracies.
Makes it difficult to use WMs that use a panel, like IceWM or Matchbox.
I did a reboot in case I had overlooked something in the
initialisation, but that's changed nothing.
Tried re-creating the tpctl.dat a fair number of times as well.

This is on NetBSD-3.0-release; but has anyone seen a similar problem?
Maybe pinpointing what to look at might help; I thought about manually
editing tpctl.dat but the syntax is unclear.

Cheers

Michael

Don't know about 720, but on my 680 the reading of raw coordinates is
sometimes unstable.  E.g. if you put debugging printfs into the
driver, you can see the press coordinates "sliding" to the right when
you lift the pen.  Even WinCE (that does a very good job at reading
presses/drags stably) sometimes suffers from this, when you drag a
dialog box to position it, and then when you lift the pen the dialog
suddenly jumps.

unable to build hpcboot

I can't build hpcboot anymore since the free/dealloc changes:

Linking...
libsa.lib(winblk.obj) : error LNK2019: unresolved external symbol dealloc referenced in function winblkopen
libsa.lib(ufs.obj) : error LNK2019: unresolved external symbol dealloc referenced in function ufs_open
..\compile\ARMRelease/hpcboot.exe : fatal error LNK1120: 1 unresolved externals

The attach patch seems to solve it, but I'm wondering... is this the right
thing to do?
