Zaurus - pdaXrom / Looking For A Volunteer

« on: July 30, 2007, 02:22:25 am »

I'm going to take a crack at maintaining this.

I believe I've brought the feed up to date, and I've done a little tidying of the packages. I've also brought up a mirror here: http://koshchei.org/feed/contribs/everyone-pdaxrom in case it's needed.

Let me know if it looks like anything needs fixing.

C1000/3x00 General discussions / Pdaxqtrom /etc/xipk.conf Error

« on: April 08, 2007, 09:18:54 am »

As I recall /etc/xipk.conf is a very simple file, containing only the path which meanie's ipk tools will use as a base for installation. For example, on my 3100 I had:"/hdd2/programs/" (without the quote marks) as the sole contents of that file. When meanie's installer ran it unpacked and installed everything into that directory. Meanie's web site mentions this, but it might not leap out of the page at you. Search that page for xipk.conf and you'll see the mention.

Zaurus - pdaXrom / New Packages Announcement

« on: April 05, 2007, 11:06:07 am »

Hugs built for (and on) pdaxii 13.

Hugs is an interpreter for the functional programming language Haskell. This is the September 2006 release, which is the most recent stable version. This is the Hugs98-Plus bundle, so there are various libraries included, most of which I have not tested.

Feed: http://www.chrestomathic.org/pdaXrom/feed/
Just the package: http://www.chrestomathic.org/pdaXrom/...-1_armv5tel.ipk

Software / Spectrum Emulator

« on: March 06, 2007, 07:36:08 am »

is there still any interest in this? I'm interested!

I have tried out a few of the standard unix emulators on my 3100 running cacko, using meanie's peerless pdaXQtrom and gcc images. Ideally I'd like something that executes in full screen (so I am aiming mostly at SDL) and at full speed.

• Fuse built (with SDL, without glib and gtk), but does not execute correctly. Looks like it gets hung up somewhere in the SDL init. I'm planning to take a closer look when I have time.
   
• fbzx builds and runs correctly, but is very slow.
   
• spectemu builds and runs correctly using pdaXQTrom. Performance is OK with sound off and the window kept small, and a bit sub-par with sound enabled (but still better than fbzx). I had to remap the x11 keyboard definitions to get a right-shift key (which is how the emulator reads symbol shift). the pdaxqtrom server appears to deliver the same keycode for  the left and right shift keys on the 3100 keyboard.

I'll see about building an ipk if anybody wants to give one of these a go.

Sharp ROMs / Hdd2 Errror After Installing Cacko From Pdaxrom

« on: August 25, 2006, 07:04:33 am »

I guess you will have to restore the partitions to their original state? Of course, you'll need to know what they are.

Trisoft to the rescue! Get SLC3000SYSPART.zip from here: http://trisoft.de/en_c3000howto.htm (about 17MB)

it contains a text file that describes the layout of the SL-C3000 partitions, and a tar file with the default contents of /hdd1

Sharp ROMs / Parted For Zaurus

« on: May 07, 2006, 08:33:31 am »

I remember someone compiling this and it worked rather well. Well I lost it during a reflash yadda yadda, whoever compiled this, is it possible to "resend" this to me?
[div align=\"right\"][a href=\"index.php?act=findpost&pid=123124\"][{POST_SNAPBACK}][/a][/div]

Hi Bam,

I built this thing. I was going to make an ipk for it, but to be honest it's not complex enough to deserve it. Just put it on the internal flash, a CF, or SD card -- somewhere other than device you want to repartition.

Usage is simple enough - if you want to resize /dev/hda3, for instance, then "umount /dev/hda3" (maybe umount all the
partitions, for safety). Run parted: "parted /dev/hda". From within
parted you can resize or create partitions (best have the mains power
attached during a resize, there can be quite a bit of disk activity as
parted moves data to free up disc blocks).

This version of parted cannot create ext3 filesystems, but it can make
the partition to contain them. I advise running fsck.vfat over the
resized partitions; while I've always found parted to be good, resizing
vfat filesystems on the fly can still cause problems.

Attached is the gzipped binary, which was built some time ago on a 3100 (running cacko, as I recall).

Zaurus - pdaXrom / Cat /proc/stat

« on: February 23, 2006, 05:44:30 am »

Hmm, I get information in the disk_io field.

C3100, latest pdaXrom beta. Lexar SD card was in, if that matters.

OESF Announcements / Possible Wiki Change

« on: January 03, 2006, 08:18:45 am »

I have no experience with geeklog (although it looks very cool, and sharing the accounts with the forum would be very useful).

I thought I'd mention that if you want to stick with wiki software I have had good results with MoinMoin, which has some Anti spam features. It's been pretty sucessful (although not 100% perfect) at dealing with spam (particularly when using the Automatic updates).

C1000/3x00 General discussions / Is There A Programme Called 'od' In The C3100 Os

« on: November 07, 2005, 06:10:37 am »

PS - on the IO error. It's just a thought, but could it be /tmp filling up (and therefore writes failing)? When compiling some things I found /tmp way too small; it fills up quickly. Setting the TMPDIR environment variable helped.

Thanks for the suggestions gds. What restricts the size of /tmp?
[div align=\"right\"][a href=\"index.php?act=findpost&pid=102541\"][{POST_SNAPBACK}][/a][/div]

By default /tmp is really a link into the /dev/shm ramdisk. This makes sense from a flash-wear point of view (and perhaps speed/power consumption as well, I don't know). The initial size (set in rc.rofilesys to 1Mb, I think) is large enough for most uses of /tmp, but gcc can sometimes create very large intermediate files and expects /tmp to be able to take them.

C1000/3x00 General discussions / Is There A Programme Called 'od' In The C3100 Os

« on: November 06, 2005, 07:45:39 am »

During the Make step it keeps looking for 'od' which is on my desktop under /usr/bin but does not appear to be present on the Zaurus. Is it necessary? The compilation progresses quite happily without it.

This isn't my main problem which is that the compilation fails with an I/O error    but I wondered whether it might be associated.
[div align=\"right\"][a href=\"index.php?act=findpost&pid=102458\"][{POST_SNAPBACK}][/a][/div]

Hi Barry,

/usr/bin/od is present on my 3100 (cacko rom - perhaps it's missing in the Sharp rom?)

It's just the octal dump program, you should be able to build it from the GNU coreutils package if you really need it. I thought there was a version built in to busybox, but maybe not.

C1000/3x00 General discussions / C3100 Harddisk Repartitioning?

« on: October 30, 2005, 12:45:46 pm »

I am trying to repartition my harddisk, to have two partitions:
- the first ( HDD3 ) - as VFAT, about 2 GB and
- the second ( HDD4 ?) - as EXT2 or EXT3

I do the following as root:

- umount /ext/hda3
- fdisk /ext/hda3
[div align=\"right\"][a href=\"index.php?act=findpost&pid=101349\"][{POST_SNAPBACK}][/a][/div]

The names you're using there look odd. On my 3100 device /dev/hda3 is mounted at /hdd3 -- I have no /ext directory.  Maybe that's a cacko thing, but the fdisk line is very fishy. fdisk should be given a device node to work on.

/dev/hda3 is the device name for the third partition on the first (IDE) device. You would normally run fdisk by pointing it at the whole disc (not just one partition):

Code: [Select]

fdisk /dev/hda
I wouldn't proceed if the fdisk banner didn't look right (a message about the cylinders on the disk being set to 7936, for instance), nor if "p" in fdisk didn't show the partitions I expected. On a stock 3100 there should be three partitions. The first two are very small (about 10Mb each) and contain disk images (I think the ROM can use these to recover a Z that would otherwise be bricked, so best leave them alone!). The third one contains all the user data.

Once "p" shows the three partitions you expect you could use "d" to delete the third one, and then "n" to add two new partitions, which would be /dev/hda3 and /dev/hda4.

You didn't ask this, but you might like to know that it's possible to resize /dev/hda3 dynamically (that is, without losing the files that are on it). I have done this to my own 3100 using GNU Parted (I had to compile it first -- drop me a line if you want the binary).

C1000/3x00 Hardware / Thinking About A Sl-c3100

« on: October 17, 2005, 06:43:38 am »

The promised photo of the power adapter I received in my order from pricejapan. I see that I misremembered the power rating -- it's actually a more generous 100-240V in.

C1000/3x00 Hardware / Thinking About A Sl-c3100

« on: October 16, 2005, 11:42:32 am »

No, not directly. The charger I received claims to take 100-220V, so it should work. The plug does not fit into a standard UK socket (I'm actually in Ireland, but we use the same sockets as the UK). You will need an adapter to convert the Japanese standard plug to a British one (I have been using the charger from my 5500 instead). I can supply a picture of the charger that comes with the Z if you want to see the connection you'll need to make.

That would be really useful.

[div align=\"right\"][a href=\"index.php?act=findpost&pid=99567\"][{POST_SNAPBACK}][/a][/div]

Sure, I'll add one tomorrow (left the japanese power supply at work).

C1000/3x00 Hardware / Thinking About A Sl-c3100

« on: October 16, 2005, 08:53:08 am »

I am thinking of getting a Zaurus SL-C3100 and I've been reading as much information as I can find but I'd like to double check.

Hi Barry, I've just received an SL-C3100 from PriceJapan, so I'll try to answer some of your questions.

It seems the best buy is probably from PriceJapan and people seem to give them a good recommendation.

I had no problem with their service at all. I ordered on a Wednesday evening, they shipped on Thursday morning and I received it on Monday morning.

Is the mains charger supplied with the C3100 useable in the UK?

No, not directly. The charger I received claims to take 100-220V, so it should work. The plug does not fit into a standard UK socket (I'm actually in Ireland, but we use the same sockets as the UK). You will need an adapter to convert the Japanese standard plug to a British one (I have been using the charger from my 5500 instead). I can supply a picture of the charger that comes with the Z if you want to see the connection you'll need to make.

Is the English conversion really as simple as changing a setting, with a text editor, from =ja to =en or is more complicated than that?

Changing the locale setting will convert most things in the UI, but not everything. There are various things you could do to finish the job, but the simplest might be to restore the "backup image" trisoft.de offers (I did this after the locale change above, and it took care of almost everything). You just need the backup image, not the NAND image. It's very easy if you just follow the instructions trisoft have.

If I need to do any of the conversion outside the Zaurus will I be able to do it with my current Debian desktop? I understand that the Zaurus accepts USB Mini A and Mini B connectors, whatever they are, so will I need special lead(s)?

I've not (yet) been able to connect my SL-C3100 to my debian machine, even though my 5500 works fine. I'm not sure yet what the problem is. In theory this should just work, however. The device comes with a standard A-mini-b connector (to connect to your desktop machine). If you want to connect the Z to a camera, etc. you'll need to purchase a "usb host" cable (mini-a to whatever).

One of the primary things I want to use it for is to look at digital camera images in the field. These will be 10MB Tiff images. Is there software available which can display these images?

I think the presupplied software can only view jpeg images. I'm sure there is something you can install.

If you will need to purchase a UK compatible power brick and a host cable then it might be worth looking at trisoft, since I believe they supply both as standard (as well as converting the device to english for you).
