Angstrom & OpenZaurus / Can't resume without reboot

« on: September 21, 2004, 07:50:22 pm »

This is a strange one.

I flashed yesterday and 3.5.1 was working fine; this evening I tried to turn my Z on (C750) and it wasn't having any of it (though the battery light came on - slightly reassuring).

Anyway, after cursing (as I don't have a card reader and my 5500 was also non-connectable), and lots of pressing the Home/Power On and On/Off buttons it eventually booted (I also pulled the battery a few times and had had it plugged in).

I then tried to suspend, and once again no joy - went through the same as above.

Anyway, I've had a look at the beast now, and the battery was completely flat (which would explain why it didn't turn on, and after plugging in and messing around it might have got back enough charge to boot). I didn't leave it on, and in any case it ought to have turned off. Is this something to do with 3.5.1? If not, I've no idea what's wrong with it :-(

Angstrom & OpenZaurus / OZ 3.5.1 bugs I've noticed

« on: September 21, 2004, 06:36:58 am »

I should really just get on and try to sort these and submit patches, but I'm busy and my dev box is too slow (waiting for a new computer to arrive :-)) - not good excuses I know, but I wanted to tell someone what I've found.

Anyway here's what I've seen:

Hotplug (I assume) still has issues: This produces the unknown USB device warning on Windows. This can be fixed by reloading the net_fd.o module etc.

Code: [Select]

#!/bin/sh
/sbin/rmmod pxa_bi
/sbin/rmmod net_fd
/sbin/rmmod usbdcore
/sbin/insmod /lib/modules/2.4.18-rmk7-pxa3-embedix/kernel/drivers/usb/device/usbdcore.o
/sbin/insmod /lib/modules/2.4.18-rmk7-pxa3-embedix/kernel/drivers/usb/device/net_fd/net_fd.o
/sbin/insmod /lib/modules/2.4.18-rmk7-pxa3-embedix/kernel/drivers/usb/device/bi/pxa_bi.o
If this also happens with the 5500/5000D then change the references to pxa_bi in the above code to sa_bi and try that

No storage_fd.o module = no mass storage.

I should get around to adding mass storage functionality to the ROM (without having to use scripts) much like what one can do with Cacko and pdaXrom (i.e. with a GUI to select). BTW mass storage also works for the 5500/5000D - just needs a simple kernel patch to make the storage_fd.o module (actually you can even use the pxa storage_fd.o module - so you can cheat in the meantime).

Terminal acts strangely when using vera font - the promt and where you type are a long long way apart.

Terminal needs larger fixed fonts (12 is the current max)

Terminal doesn't close windows when you 'exit' in them.

The clock should default to the build date rather than 1/1/1970 IMHO -> shouldn't be too difficult to change.

Medium mount dialogs which come up before the screen has been calibrated are not too useful; best to take the cards out when you first boot (but a software fix would be good).


Well done to the developers.

Off Topic forum / Devnet corruption?

« on: August 29, 2004, 08:04:15 am »

I was looking for a bit of a post which I know exists in here:

http://www.zaurus.com/dev/board/index.php?...topic=3250&st=0

But couldn't find it.

Take a look at this page:

http://www.zaurus.com/dev/board/index.php?...opic=3250&st=17

Specifcally the posts by drboom - pretty easy to spot; then use the page links at the bottom - it doesn't show up (not for me anyway). I thought I was going mad until I tried the search function and discovered that it was actually there.

So then I tried manually changing the '&st=' number; I assume this says which post to start at, but it doesn't actually work that way - I've stepped through from 0-15 and the pages just turn up at random.

Any suggestions, or am I really going mad ;-)?

Cheers,

Angstrom & OpenZaurus / Note: ipkg cannot be used concurrently

« on: August 27, 2004, 09:16:47 am »

I reflashed OZ3.3.6pre1 onto my C750 last night, and in a bit of a rush to install everything (and remove stuff I didnt want), I had two ssh terminals and aqpkg open and doing stuff.

Now it had dawned on me that perhaps running ipkg in more than one terminal was a bad idea, but I hadn't realised that aqpkg holds the status file (I assume) open until it's closed (actually this may not be strictly true - I had just removed some stuff using aqpkg and may well not have pressed the okay button to get rid of the status window).

Anyway with Z in this state I installed a bunch of packages using ssh, and started to get dependency errors. After doing this for a bit I ran 'ipkg status' and only had the 4 packages I'd just installed shown as installed.

As I said, just a note to mention this so no-one else gets caught out.


Si

P.S. I guess that using a lock-file for the ipkg data files is the way to fix this; it ought to be a relatively simple matter - after the write-up! ;-)

Off Topic forum / How do game auto-select settings work?

« on: August 27, 2004, 07:27:00 am »

This is certainly off topic ;-)

I was playing Far Cry yesterday, on my (old) P4 1.4GHz, 256Mb RAM PC which I've just given a GeForceFX 5700LE 128MB graphics card. The card's not the best out there but it's reasonable and it was cheap.

Nevertheless when I clicked on the game's automatically-set-your-own-settings button it defaulted to the lowest for everything (same happens in Doom3 BTW), even graphics related stuff. I thought this was a bit odd as the graphics card is reasonably good, even if the processor and amount of RAM in the PC aren't.

So basically does anyone know what the auto settings stuff actually looks at? Or is my slow processor etc. overriding the graphics card's abilities?

Cheers,

Angstrom & OpenZaurus / ipkg-link doesn't obey /etc/ipkg.conf dest entries

« on: August 20, 2004, 01:32:43 pm »

ipkg-link is a script and it's hard-coded with the 'dest' locations.

If I decided to create a new installation point (by adding the dest ... line to /etc/ipkg.conf) this is not picked up by ipkg-link.

This is not a major issue unless you have a C machine and want to use your /home directory to install stuff too.

Has this been fixed in a later version or shall I set to work updating it?

Cheers,


Si

Zaurus - pdaXrom / pdaXrom 1.1.0 - Power status notifications?

« on: August 19, 2004, 07:20:07 am »

Is it possible to receive power status change notifications?

I'd like to run xscreensaver, but only when on external power.

Zaurus - pdaXrom / pdaXrom 1.1.0 undefined symbol: __udivsi3 ???

« on: August 19, 2004, 07:18:27 am »

I get this error when trying to run things which used to work on 1.0.5.

For example Xcas/Giac (which was compiled on the skiffcluster) and swfplayer (which I cross compiled, probably with the pdaXrom toolchain - but I can't really remember).

Any ideas for a fix, or will I have to re-compile everything?

Cheers,


Si

P.S. A few more things which come up with the same error: gnuplot and xscreensaver

Off Topic forum / Reverse engineering an IR protocol

« on: July 30, 2004, 10:18:22 am »

I'd like to be able to download my blood sugar readings from my meter to my Z (I'm diabetic). I have some software on the PC which can download the readings, but the Z is of course best ;-).

I hope the protocol will be fairly simple - you just hold down a button on the meter and it starts spitting out data to the PC once they've enstablished comms. It must also pass its current time as the meter can be reset if the clocks change, but that's about all it can do.

Anyway I've never tried anything like this before and was just wondering how to go about it?

I presume some tools like LIRC, xmode2 will be required, I have an IR serial adaptor.

Any suggestions gladly accepted. I'll be doing the development work on a desktop Linux box for the most part - though I may need to use the Z to record the PC's part of the conversation (as I dual boot Windows & Linux at home).

Cheers,


Si

Off Topic forum / Best setup for (almost) prehistoric Linux box?

« on: July 26, 2004, 07:18:56 pm »

The only Linux box I have connected to the 'net (at a decent speed - T1 at work) is rather old. Unfortunately as it's the only one on the 'net and I want to be able to do a variety of things with it (like develop with OE! which does sort of need a 'net connection).

Anyway it the GUI is stupidly slow (which is the most painful bit of using a system). It's a PII-400, 64MB RAM, 40GB disk space and using Mandrake 9.2 and KDE at the mo.

Firstly, what can I do to make it go a bit quicker? I know KDE is bad news, what would people recommend instead by way of WM and filebrowser? I have the default services plus ssh turned on, I've looked through them and it seems to be a pretty minimum sort of setup so I don't think there's much to be gained here.

Mozilla seems to be very very very very very slow, is there anything equally good (or nearly there) and free to replace it? Equally, trying to start an xterm takes ages (usually when there's something else going on in the background). Not good.

If Mandrake just won't work, then which distro would people recommend I move to?

Cheers,

Zaurus - pdaXrom / Compiling Scilab

« on: July 13, 2004, 06:04:12 pm »

I'm currently trying to compile Scilab.

I'm using the pdaXrom toolchain.

Source from here: ftp://ftp.inria.fr/INRIA/Scilab/distribut...-3.0.src.tar.gz

See also: http://scilabsoft.inria.fr/

Configure script had to be edited to recognise arm-linux-unknown-gnu as the system type. Edited configure file is available from: http://students.bath.ac.uk/enpsgp/Zaurus/configure.zip

(the changes are my first rough try - I've no real idea what I've enabled, etc., but it seems to work after a fashion)

This is the configure command I issued (it worked BTW ;-)):

./configure --host=arm-linux --without-xaw3d --with-g77 --x-libraries=/opt/arm/3.3.2/armv5tel-cacko-linux/X11R6/lib --x-includes=/opt/arm/3.3.2/armv5tel-cacko-linux/X11R6/include --with-local-xaw --without-pvm --without-tk

Then:

make all

It falls over complaining about not being able to find some xaw related static libs. I was under the impression that it makes its own (the --with-local-xaw bit).

Anyway if anyone can shed any light that would be great. I also wonder whether the 3D (and normal) xaw libs are available and tc/tk too?

Cheers,

Software / R updates

« on: July 01, 2004, 02:43:57 pm »

My apologies to those who have tried to download R 1.9.0 or 1.8.x as the link from the download page was broken.

It should now be fixed: http://sgp.zaurii.net/binaries/

I've also 'fixed' ;-) the 1.7.x packages to use tar.gz rather than ar ipk encoding.

Enjoy,

Site Suggestions, Requests, and Updates / Search string length ;-)

« on: June 26, 2004, 11:23:06 am »

I'd forgotten all about this. lol.

For those of you who remember (me on) the devnet forum, I was always nagging to get a shorter minimum search string length.

This forum currently only allows search strings of 4 chars or longer.

Could we reduce this a bit please (I always reckonned 2 would be useful - CF, SD, etc., but I suppose it depends on how much processing power you want to throw at it)?
