Most pieces of the puzzle seem to fit.. 
After hours and hours of trying, interpreting and changing of code, problem guessing, debugging, reading logs, kernel rebuilding and device flashing I finally succeeded in waking the Zaurus up after suspending it. Man, you wouldn't believe how much time I spent on getting something "simple" as turning On and Off the device to work.

So, result is that since this afternoon I have the latest 2.6.30 kernel working on my SL-C3100. There are still some things to fix, but most things seem to work... finally!

Update:
Some of you already requested a link to download the kernel, so here it is then. The 2.6.30-rc2 SL-C3x00 kernel (MD5: 43b691cc05a3c1aa694a287b34aefc23) and the corresponding SL-C3x00 modules (MD5: bc13ae45d2e79e6987d9ba60f75fa206) are both highly experimental. Bear in mind that, as said, some things need to be fixed.

Update 01-05-2009:
I've build the latest 2.6.30-rc4, this time with support for CPU frequency scaling and Android and I added various wireless LAN drivers (as modules).

Update 08-05-2009:
New update using the latest 2.6.30-rc4 kernel. This version fixes the screen flickering and the unexpected (hard!) hangups. I had to disable the CPU Frequency Scaling to get it stable, so I guess that needs more work. Until now this one is very stable. I've added more kernel modules as well. Since the previous version was buggy I've simply overwritten it with the new one. Please re-download!

The kernel should work on the SL-C3x00 (Spitz) as well as the SL-C1000 (Akita).

2.6.30-rc4 kernel: Download (MD5: d92771c86cd7c53cabd1bd216eac5a0f)
Kernel modules: Download (MD5: 377c155df6fd1fc569188ddafa282af6)

Again, please give it a try and give me feedback on your findings!

What's going on at Omegamoon headquarters... 
You may ask yourself why it is taking so long before a fresh new Zubuntu release is uploaded on this site. Well, I was asked some time ago by an Ubuntu developer to get all Zubuntu related packages into mainstream Ubuntu, so it could become part of the upcoming 9.04 Jaunty release for ARM.

First and most important package would be the kernel, so I've been working on getting a working 2.6.28 in the last couple of weeks, resulting in a more or less working kernel. But I'm having some major issues, power management isn't working for instance.

So this is taking a little longer than I expected. The current 2.6.28 kernel I'm using has support for the ext4 filesystem, build-in support for Android, and I'll try to incorporate CPU Frequency scaling as well, so we can overclock the CPU and try to fry an egg on our Zaurus ;-) I guess I have to sit through another series of kernel debugging session before this kernel is ready for release. The CE-170TS serial cable I kindly got donated from Rolf Leggewie is doing overtime currently.

Parallel on this, I'm in the process of extending the kexecboot boot manager. A lot of ideas have been passed on at the #kexecboot IRC channel. Feel free to join us there by the way, although we might bark sometimes, we certainly won't bite. So expect to see autostart functionality, ext4 support, customized logo and icons, (re-)ordering of items and much more in an oncoming release of the boot manager.

So, to cut a long story short, there's a lot going on behind the scenes. Plan was to release a Zubuntu Jaunty combined with the 2.6.28 kernel and the new boot manager. But since this could take a while to finish, I might upload a new root filesystem based on Jaunty using the 2.6.26 kernel. Give me a shout and let me know what you think!

Last but not least, Google has cut me off from their Adsense "service" because of alleged misuse. My account "has posed a significant risk to AdWords advertisers". Bullocks of course, they just didn't like paying me. But anyway, this means I have to ask you all to use the "Donate" button if you like what I'm doing and are willing to support me. Thanks in advance!

Zubuntu meeting Jaunty Jackalope (9.04) - First Impressions 
I've been very busy the last couple of weeks sorting out various Zubuntu-related problems. I'm glad it seems to work for most of you, and hope you like it.

I was contacted recently about the Ubuntu for ARM initiative from Canonical. I always thought that this was targeted at the armv7+ family of CPU's, but to my astonishment this seems not to be true! This means that the latest (unstable) Ubuntu should technically spoken work on our beloved Zaurus.

So that's why I started another 'proof of concept' just to see if it is possible to get Ubuntu version 9.04 (Jaunty Jackalope) running on the Zaurus.




The images speak for them self I guess. I've got it all set up now, using most of the applications from the Zubuntu 1.0 RC1.

The system is running a stock Ubuntu 2.6.28 kernel with most of the packages 'as is' from the official Ubuntu repository.

This is just a first impression. Pretty cool so far!

Running Zubuntu from internal flash memory 
I finally took some time to document the steps needed to get Zubuntu running from internal flash memory. It's quite easy actually, as always, as long as you know what you're doing.

The following procedure copies most part of Zubuntu into internal memory. Unfortunately the complete distribution is too large to fit completely into the little memory available, so a part has to be made available on SD, CF or Microdrive (see the Postinstall for more info).

It is important to now that the only drawback currently is that you have to keep your SD card inserted during use of Zubuntu, since (on default) the /usr and /var directories are located there. If your model has a Microdrive, you'd better install these two directories there, in order to make this disadvantage disappear.

Disclaimer: First of all, be aware that, if you've previously had the original Sharp ROM, Cacko, pdaXrom or any other distro running from internal memory, you will lose it permanently after following these instructions. If you're not sure, be sure to make a NAND backup before continuing. How to make a NAND backup is described here (kind of).

1. Making preparations
These instructions assume you have a Zubuntu installed as described here. There are plenty of other possible installations, but I'll only cover the default here.

Download the following two files:
  • mtd-utils_1.1.0+git-r1_arm.deb
  • MD5: 01a45a3a6aa71dde9611160e943bcd1e
  • zubuntu-flash-install.sh
  • MD5: 45a629b112088394efad3aeba61dc861

    2. Start Zubuntu
    After setting up Zubuntu, you should be able to select it from the bootmenu. Select it there so Zubuntu boots and login with the root user account. Copy the downloaded files from step 1 onto the Zaurus.

    3. Installing required packages
    Install the mtd-utils package downloaded in step 1 by executing the following command:
    dpkg -i mtd-utils_1.1.0+git-r1_arm.deb

    4. Copying Zubuntu
    The rest is just a matter of copying over the base system. Since this can be tricky, I've created a small script to do the dirty work. Run the script by entering ./zubuntu-flash-install.sh.

    You'll be asked on which memory partition you want to install Zubuntu. Possible options are the second and third memory partition, being the Root and Home partitions of the original Sharp ROM. Default choice is the third partition since this is the largest one (about 90Mb on Spitz/Akita). After that the partition is erased (permanently!) and most of the Zubuntu system is copied from your currently running system. This also means that all adjustments, settings and configurations are preserved.


    You can safely ignore the messages 'ignored sockets' and 'implausible old time stamps'.

    5. Post install stuff
    After running the installation script there are still a couple of things to do.

    ** /etc/fstab adjustment
    Remove the mount point to the Zubuntu default installation (/dev/mmcblk0p1 on default) from the /etc/fstab file.

    ** Adjust the symbolic link to /usr and /var
    Since the complete Zubuntu distribution is too large to fit completely into internal memory, both /usr and /var have to be made available on SD, CF or Microdrive. The installation script creates two symbolic links for this purpose, pointing to /dev/mmcblk0p1, being the first partition on your SD memory card. You need to adjust it only if you've installed Zubuntu on a partition other than the first one on your SD memory card.

    ** Adjust /etc/rc.S/00mount-zubuntu.sh
    This file mounts the Zubuntu default installation early in the boot process, since files in /usr and /var are needed during boot-time. The mountpoint used in /etc/rc.S/00mount-zubuntu.sh is /dev/mmcblk0p1 on default. You need to adjust it only if you've installed Zubuntu on a partition other than the first one on your SD memory card.

    6. Reboot from internal flash memory!
    Now reboot your Zaurus (run reboot). You'll notice that there's a new option in the bootmenu with a litte memory icon in front. Select that option, and Zubuntu boots from internal flash memory!

    7. Footnote
    Please give me your feedback, report problems, share fixes, enhancements etc.

    Last but not least I want to stress the fact that visiting the advertisements on the left or (even better) use of the Donate button is much appreciated!

    Have fun!

    Zubuntu 1.0 RC1 ready for take-off 
    I've uploaded Zubuntu 1.0 Release Candidate 1. Instructions on how to install this on your Zaurus can be found in the menu on the left, or here.

    I've tested this on my Zaurus SL-C1000 and SL-C3100 devices. I also succeeded in running Zubuntu from internal flash on the SL-C1000, which is pretty darn fast!

    I still have to document how to get Zubuntu running from internal flash. I'll post it here when ready.

    Update:
    Use xbindkeys-config to add new keyboard shortcuts. This is how the brightness keys are controlled currently. It's possible to use xautomation (xte), so Fn-Up, Fn-Down, Fn-Left and Fn-Right now moves the mouse cursor. Quite cool!

    Update:
    I'm rebuilding the kernels for all models with build-in support for sound, bluetooth, pcmcia and infrared. I'll also include modules for more (wireless) network adapters. I'll report here when they're ready!

    Important update for Spitz owners:

    Please re-download and install the bootmenu-kernel and the root-addition archive. This should solve some of the problems reported.

    Keep those advertisement clicks coming, but only if they're sincere of course. Or you can use the Donate button on the left, Feel free to do so!

    Zubuntu 1.0 update... 
    I'm currently finishing off the 1.0 release of Zubuntu. Zubuntu is based on Ubuntu 8.04 "Hardy Heron" using the Mojo "Hasty Hippogriff" repository on top of a Poky 2.6.26 kernel.

    There will be two versions, Zubuntu-Base and Zubuntu-Desktop.

    The Zubuntu-Base contains "just" the kernel, a working X Server and some basic applications. I leave it up to you to decide what additional packages to install. A lot of the applications can be installed directly from the Mojo repository.

    The Zubuntu-Desktop contains, apart from all the packages in Zubuntu-Base, a more complete set of standard applications. Only packages missing currently are PIM applications (Calendar & Contact).

    Both Zubuntu distro's will be targeted at the Zaurus Spitz (SL-C3x00) and Akita (SL-C1000) models first. I'm still in the process of getting an alternative boot kernel (kexecboot) working for at least the SL-C7x0 and SL-C860 models, but this will take some more time I'm afraid. I recently acquired a Tosa (SL-C6000L), but I still have to check what is needed to get Zubuntu working on this specific model.

    Features

  • Linux Kernel 2.6.26, EABI only, patched for use with Android 1.0
  • Sound: Tested and working, including volume control on the back of the device
  • Touchscreen: Tested and working
  • Network: Tested and working (tested with Linksys WCF12, Buffalo WL12-CF-S11, Billionton CFLT2-10B)
  • Rotation: Automatic rotation in X Server once the display is flipped.
  • Brightness control (Fn-3 and Fn-4): Tested and working
  • Bluetooth support: Added, but untested
  • USB Host: Added, but untested

  • Installed applications in Zubuntu-Desktop

  • Desktop:
  • LXDE
  • Launcher:
  • LXLauncher (installed, but disabled on default)
  • File manager:
  • PCManFM
  • Multimedia player:
  • Audacious
  • Web browser:
  • Firefox 3. Thinking about replacing it by Midori.

  • Network manager:
  • WICD
  • Text editor:
  • Leafpad
  • Word processor:
  • Abiword
  • Spreatsheet:
  • Gnumeric
  • Email:
  • Sylpheed
  • PDF:
  • xPDF
  • Instant Messenger:
  • Pidgin
  • Games:
  • xMahjongg

    Additional extras

  • Android 1.0. Will become available later as a seperate download

  • Help wanted

    Some of you offered help already. Thanks a lot! If you're able and willing to help in any way, please drop me a line using the "Contact Me" form, and we'll see what we can work out.

    Zubuntu 1.0 coming up... 
    This is a screenshot of Zubuntu 1.0. It is currently running on my SL-C3100. It's very stable, runs a 2.6.26 Linux kernel and includes all the Android 1.0 patches.



    Based on Ubuntu 8.04 "Hardy Heron" I used the Mojo "Hasty Hippogriff" repositories. Bravo to the guys from the Mojo project. A job well done!

    I'm currently using the Xfce desktop environment. A lot of standard applications have to be added, but the hardware support like sound, touchscreen, auto rotation, network etc. seems to work.

    More on this later :-)

    Android 0.9-beta for Zaurus SL-C3x00 (Spitz) 
    Sorry for the delay, but I took some time off and spent the last two weeks in beautiful Italy (Tuscany/Umbria).

    Now, plans were to combine two ongoing projects of mine, Android and Zubuntu, and make it into one distro. But I'm still having too much problems with Zubuntu (I'm working on the 8.04 release) so I switched, for the time being, to Poky. I read that OpenenedHand was recently acquired by Intel, so we might see some (more) of Poky back in Moblin in one of the next releases.

    So what you download and install here is mainly a Poky distro in the first place. It's very stable and pretty complete. Give it a try, I like it better each time I see and use it. It's based on a 2.6.26 kernel patched for Android. Although the Android SDK was based on a 2.6.25, I ported the patches needed to get it working in 2.6.26.

    Android is pretty basic I guess. I didn't test all features, and I'm sure that a some things don't work yet. Like the touchscreen for instance.

    Installing Poky & Android

    Installation on the Zaurus is done in the usual way:

    1. Download the following files and copy them to a SD card.
  • zImage.bin
  • updater.sh
  • gnu-tar
  • android-root.tar.gz

  • 2. Remove battery and power adapter cable
    3. Wait for 5 seconds
    4. Replace battery, close and lock battery cover
    5. Attach power adapter cable
    6. Keep OK button pressed while pressing on/off switch
    7. From the Japanese menu, choose option 4 (Update), then 2 (SD) and finally Y

    Flashing starts, and you are asked if you want to flash the kernel, if you want the microdrive to be formatted and if you want the root filesystem to be installed. Accept all questions answering them with y

    After flashing is complete, the machine is rebooted and Poky starts. First boot takes some time because of initial configuration taking place.

    Now, before getting on to Android, play around in Poky and see if you like it. It's really worth a try!

    Starting Android

    You have to exit the Poky interface by pressing Ctrl-Alt-Backspace simultaneously. On the prompt, press Enter and login with user root. No password is needed. Now type:
    chroot /home/android /init

    Android should boot now.

    Exit Android

    I haven't found a better way, so let me know if there is one. Press Fn-Right to see the Android console, and type "reboot" to reboot the machine. Poky will be (re)started.

    Enjoy Android, and hopefully Poky. Thanks again for Speculatrix for sharing some hosting space. Much appreciated!

    By the way, if you like what I'm doing, be so kind to click on as much advertisements (on the left) as you can.
    :-)

    Cheers,

    Anyone in for another Android experiment? 
    It has been quite a while since I last posted here. I'm busy doing all kinds of things at the same time, not able to finish any of the things I started here. I'll spare you the details.

    Anyway, since Google released a Beta of Android for us to play with two days ago, I was just thinking if this would be of any interest.

    See for yourself here. The user interface has been revamped pretty extensively. It looks great!

    So, anyone in for another Android experiment then?

    SDK download can be found here. I dusted off my developer tools already to see if I can make this work on my Zaurus again
    :-)
