Angstrom & OpenZaurus / Mplayer + Oz 3.5.4.1 On Spitz?

« on: August 19, 2006, 11:20:59 am »

I've encoded a movie to a 320x240 , mp3 encoding. I've tried playing it with mplayer on a C3000 machine. However, it uses libsdl which is not functioning too well on this machine.
The -vo fbdev option makes mplayer play this movie in a smaller scale. I found a thread (https://www.oesf.org/forums/index.php?showtopic=20473) explaining how to fix it up for fbdev playing on a C860. However, the problem is that I cannot control mplayer - no stopping, skipping forward or backward. Makes it not really usable even if I manage to view it correctly full screen.

The error spit out from SDL (inside mplayer) is something in the lines of:
Can't detect machine defaulting to SL5000D detected machine is 'Sharp SL-5000D'

Any suggestions? How to make SDL work correctly with this? Or on a different direction - how to encode movies for playing with the built in opie player?

Angstrom & OpenZaurus / Sdl With Oz 3.5.4.1 And A Spitz

« on: July 18, 2006, 01:28:22 am »

I was playing around with the new (and cool) OZ 3.5.4.1 . I have a spitz machine (C3000) and when trying SDL, every SDL program I used would not work well - I'd get it duplicated 3 times over the screen, interleaved with the background.
Apperently SDL patches are quite shaky, but I was wondering if I'm the only one expiriencing this - maybe a reflash would fix some things.
That's what Mickey told about the SDL patches:

I'm afraid the SDL patch for Qt/Embedded based environment needs _much_
work. It is a pretty ugly mess that grew historically. Starting with the
japanese guys forking SDL 1.2.5 years ago and not contributing their
changes back to mainline. What's worse, they added SharpROM specific
code that was hardly usable for anything other than a Zaurus.

The SDL patches would need a complete overhaul and recreating from
scratch trying to get it into mainline. It's just a question of who's
motivated enough to do that.

Deals and Great Z Buys / Where To Find Socket Bluetooth Cards?

« on: July 17, 2006, 06:03:18 pm »

I am attracted by Socket's small form-factor when it comes to CF cards - There would be no reason to take out the bluetooth card every time I fold my zaurus. The question is - how do I get my hands on such a card cheaply? Each retail site is as high as 90$ (without shipment) and I can't find them on eBay (there's only one for sale going on now). Is anyone familiar with a cheap store for such?

Thanks!

C1000/3x00 General discussions / Request For Mtdblock0 Image

« on: May 06, 2006, 05:39:12 pm »

I'm trying to debug a problem with my zaurus (you can read about it's unique situation in https://www.oesf.org/forums/index.php?showtopic=19234 ).
For that, I need an image of /dev/mtdblock0 (preferably also of /dev/mtdblock1) which you can get using the dd command.
If someone can please get both of those images and send them to me, I will be very gratefull.

C1000/3x00 General discussions / Yet Another Broken C3000

« on: May 05, 2006, 09:16:48 am »

I do apologize for the long post. I have tried many things (detailed here) before asking help from this forum. At the moment (after 2 days of fiddling), there are many threads to the story. I will, however, try to make it short.

The zaurus wouldn't boot (with misc. kernel patnics) a few days ago. Figuring out I couldn't debug it, I tried getting into rescue mode with the updater.sh.rescue (an old-time friend).
That's where I had a surprise waiting. The CF card would not be recognized by the updater menu (Holding OK while powering on, then 4->1->Y). It would yell something about missing CF card and then rebooting.

Right. There's the D+B rescue boot console. Boots pretty well, except for one (not surprising by now) thing: the /sbin/cardmgr would output an error message (something like encountering an unexpected word or ")".).
Then, I could not access /dev/hdc, even for backup purpose. I'd get the error that block-major-3 is missing (as well as block-major-22 on /dev/hda). Great.

Obviously, something was wrong with the rescue boot rootfs. I could not flash a new kernel/distro, as the CF card would not be recognized by the updater (Which uses the emergency rootfs to boot when upgrading).
Using an SD card was an obvious solution along the way. However, when I use it, the updater is yelling misc messages about /var/lib/pcmcia/stab missing (which may be correct, since it's using the rescue rootfs, which is somewhat broken).

Booting again into the rescue rootfs and diagnosing things a bit, I found out that /sbin/cardmgr is broken! it's md5sum with an old version of cardmgr was different. Moreover, mounting /dev/mtdblock2 and copying cardmgr from there to /sbin/cardmgr on the rescue rootfs and then restarting pcmcia, works.
However, /dev/root on the rescue partition is /dev/ram0 -> the kernel is extracted dynamically from the rom (mtdblock1 maybe?) to the ram.

Right now, my ROM (cacko 1.23b) wouldn't boot, due to misc kernel panics, and I am unable to upgrade to any other distro (or even sharp's original rom) because the rootfs is fucked up.
What I'd like to know, is that:
1. Wouldn't a NAND restore will rewrite /dev/mtdblock1 ?
2. Is the rootfs actually taken from mtdblock1?
3. Fortunately, I have a backup of mtdblock1 I manually made after some previous restore. I would like to copy it (via dd) to /dev/mtdblock1 on my Z. However, I am unable to mount it (via loopback interface) to check what's inside and see if there I have a correct version of cardmgr. Does anyone know about the image structure of /dev/mtdblock1?

I will appreciate any help.

User Request for Applications / Bluegps Compiled For Zaurus

« on: February 21, 2006, 05:47:32 pm »

Even though nobody requested it, it might be usefull for some:
I have a royaltek RBT-3000 (RBT3000) unit, and I needed a tool for downloading the data logs from it.
A small utility exists  here but of course, a compiled version of it for the zaurus is a bit tad difficult to find.

I've compiled and uploaded statically and dynamically linked versions to my homepage as well as attaching the statically compiled version here (with libgcc and libbluetooth built in).

C1000/3x00 General discussions / Network Connection Quickly Closing

« on: February 16, 2006, 03:47:08 am »

Hey,

I'm using an AmbiCom CF WLAN card to connect to an open network. The problem is that in a few seconds, before I manage to open any network application, the connection wizard says it doesn't find any connections and when I press OK it takes the interface down. If I'm quick enough, I am able to ping/ssh somewhere and get a connection. Does anyone have an idea where can I extend/cancel this check for connections?
(Edit: Oddly enough, if I connect from the Settings -> Network panel, there is no problem)

C1000/3x00 Hardware / Power Problems - Zaurus Blanking

« on: June 25, 2005, 04:53:47 am »

It happens to me sometimes, when using a power adapter connected to the Z, that the zaurus's screen will go blank. It's still active but everything on the screen is hardly visible.
I have to reboot it to get it working again. In addition to the screen being blank the zaurus stops charging (the orange light turns off). Has anyone else expirienced it? Is it somehow solvable?

C1000/3x00 General discussions / Prism2 Based Card Wouldn't Do Basic Stuff

« on: June 21, 2005, 06:09:28 pm »

I have a prism2 based card (AmbiCom WL1100C card) and I'm using the cacko beta rom for the C3000.
Problem is kismet wouldn't work now. wellenweiter works, also tcpdump (when I put the card manually in promiscus mode) but kismet says:
[root@thumper: /home/etc/kismet_qt/card_schemes]# kismet_server

wpa_supplicant also fails saying:

I havily suspect that sometihng is wrong because I upgraded to tetsu's 18a kernel, but I cannot verify.
Can anyone input on this?

C1000/3x00 General discussions / Zaurus Dying - Screen Rotated

« on: June 03, 2005, 05:13:45 pm »

hey!
after installing mplayer, bvdd 0.3.1 zplayer and kino2, I was able to play around a bit and show movies.
However, after I started playing oggs kino2 reverted the screen orienation (the screen was flipped, not rotated).
After rebooting the Z botted without asking me for a date and the light, volume and key mapping settings got back to default.
what's worse is that the screen is now rotated as if I have physically rotated it and it wouldn't rotate back to the original state.
Last time it happened I thought it was because I filled with / of mtdblock3 with modules and concluded that I should re-install it.
I really don't want to spend another day re-installing everything.

Any ideas?

Thank you

C1000/3x00 General discussions / Bluetooth On The Sl-3000?

« on: December 07, 2004, 06:17:46 pm »

I have been trying to set up bluetooth with the bluez drivers and apps. Sadly, that's not a howto - I did not suceed. The main thing that lacked was drivers for the 2.4.20 kernel. I had drivers for the 2.4.18 so I used them, but it caused kernel panic (though the drivers would load).
Did anyone have any success? Got the drivers compiled for the 2.4.20 kernel (now that you can fetch the source) ?

C1000/3x00 General discussions / Keyboard And Power Issues

« on: November 22, 2004, 03:55:45 pm »

Hey,
I've got my SL-3000 at last.
After tinkering around a bit with it, I wonder:
1. Where can I see the full keyboard mapping for it? for example I had to explore for a while to figure out how to make { (that's ctrl + <).
2. Can I modify the keyboard layout? There are two japanese buttons which I have no clue what they do, and I'd like to map one of them to / (currently I have to use shift+. to get it).
3. Sometimes, my zaurus fails to resume from suspend - While connected to the poor 1 amp charger I got with it, I press the on/off button and the Z flickers the screen then dies. I have to remove the battery and press the reset button to turn it on. Any ideas?

Thank you,
ERan

5x00 Hardware / Zaurus charging mess

« on: October 22, 2004, 09:56:06 am »

I'll describe what I did to my zaurus, but the end result is that it can't charge the battery so I have to keep it on power so it won't drain the battery (which I charge externally).

I connected the zaurus to a car charger with reversed polarity. After finding out it doesn't charge I reversed the polarity and everything worked fine.
At some time I noticed my battery charge indicator wouldn't turn off, and the battery wouldn't charge.
I started reading about, mostly getting help from these forums. At first I thought it was a problem with ROM voltages, so  I tried adjusting and re-adjusting to no avail.
At a certain stage I decided to check voltage on the battery (after externally charging it again) while the Zaurus works.
I connected wires to the battery terminals then ran the zaurus. I noticed that the voltage rises when I connect AC power, but eventually concluded that this was because the battery was not in use. However, the voltage did not rise high enough to charge the battery, so it seems the charging circuit is dead.
a bit more of looking around and I found these posts:
http://externe.net/zaurus/forum/viewtopic.php?t=620
https://www.oesf.org/forums/inde...t=0&#entry45112
From the second one I've learned that someone encountered it and had his zaurus repaired.
I wonder if someone tried to resolve such an issue by himself - I live in Israel so mailing the zaurus to Sharp USA just to get a repair estimation could be very expensive.
So, any suggestions?
