Upgrading C3000/cacko To Tetsu Kernel

[danboid]

Jon- can't help you as I've not got a C3100 so I don't know if that kernel works or not

pyknite-

I assume your update worked. You should notice now you have a much more accurate battery monitor and that you can use the iwmmx mplayer so you can play back smooth video. if you weren't bothered about either of those features then you've probably wasted your time!

the kino2 homepage has links to the iwmmx mplayer package- kino2 is a great front end for it too.

danboid, should I try the C3000 version on my C3100?
If that isn't possible, I'll have to use restore, I guess..
It's cycling thru the mentioned errors every 5 minutes now.

Jon
EDIT: I just downloaded the C3000 versions. I'm going to try it because my only other option now is full restore anyway..

Just as I thought, the C3000 versions won't let you install them on a C3100
I got this error in the install

MODEL:SL-C3100
ERROR:Invalid model!
Please reset

This is why I first downloaded the C3100 versions of these files,
the only difference being the binary file is zImage-v18b-C3100.bin instead of zImage-v18a-C3000.bin
18b verses 18a. I guess it's time for a restore..
BTW, I have the first full season and all of this season of "Lost" in xVid format (349mb files) HDTV. This is why I tried this. These files won't play very well without re-encoding them.

Just reflashed with cacko 1.23, everything's fine now. It's like a fresh install of Windows, have to get all the settings I liked back.

If anybody is wondering what files you need to copy under cacko to backup the in-built calendar's data, get all the files in

/home/zaurus/Applications/dtm

For those new to Linux, here are complete instructions

BACKING UP SHARP/CACKO CALENDAR

If you're copying these files onto a FAT formatted SD or CF card, I would use tar to back them up like this to be on the safe side. Open konsole, then enter:

cd /home/zaurus/Applications
tar cvf calen.tar ./dtm/*

cp calen.tar /mnt/card/Documents

for copying to SD, for copying to a CF use

cp calen.tar /mnt/cf/Documents

you can then unmount the disk by clicking the little zaurus icon in the task bar then clicking on your cards icon to eject it.

RESTORING SHARP/CACKO CALENDAR

First get rid of the existing calendar by doing

cd /home/zaurus/Applications
rm -rf ./dtm

Then, as your normal user (ie not as root) copy calen.tar into /home/zaurus/Applictions and extract it with

tar xvf calen.tar

For some reason I find you need to reboot the Z before it updates its calendar so you'll need to do that now and then you should find your calendar restored.

I followed the instructions just as danboid mentioned above, except I downloaded the C3100 files for my C3100.
zImage-v18b-C3100.bin
updater.sh.c3100
I renamed these files and the install seemed to go fine until I reset my zaurus with the stylus in the battery compartment hole.
It rebooted and it is now stuck on a long list of errors:
There are only 2 errors showing now. The first error is repeated 7 times. It is:

ERROR: /usr/sharp/etc/launch.conf -- can not open file
ERROR: launch.conf -- can not open file

The second error is at the bottom and it is:
INIT: id "ln" respawning too fast: disabled for 5 minutes

I have waited at least 15 minutes and nothing has happened. The curser is blinking below this second error, but nothing is happening. I can't type into the screen either.

Is it bricked at this point?
Should I use my restore, and restore my Z

Thank you for any suggestions,
Jon
EDIT: I'm now able to type into the screen now. Any suggestions what I could try??

Same pb for me.....

[danboid]

Sorry I can't help, but I've used those instructions I posted above again today and it successfully upgraded my C3000 kernel again no probs.

If you download the files on your PC under Linux before copying them onto a CF or SD card

DON'T

do it under GNOME. Under all the distributions I've tried GNOME's handling of USB disks (like card readers, memory sticks and Zaurii acting as a USB drive) is dodgy and doesn't always work. Either copy the files under KDE or from the command line and then make sure the disc is totally unmounted before unplugging. You could avoid all this hassle of course by downloading the files on yr Z instead

[Jon_J]

I abandoned the idea of using the above files to upgrade the kernel.
Doesn't Cacko 1.23 come with the latest version of the tetsu kernel anyway?

I have Cacko Lite installed now. I don't have any movies encoded for my Z at the present.
These are downloaded episodes of the TV show: "Lost"
These movies play, but stutter and have a few sync probs, so I've given up on playing these movies on my Z
They are Xvid encoded (hdtv.lol.avi)
Properties of these reported by GSpot (windows) are:
349MB
Audio: 119kbps 48000 HZ
Video: 948kbps (Frame size: 608 x 336)

I can try to re-encode these, but it takes a lot of time to re-encode these to a PDA compatable file.
I've tried a lot of the methods suggested here,
but those suggestions are mostly for re-encoding MPEG2 DVD files.
What I did to enable these to play on my Palm is below:
Use TMPGEnc to convert to DVD spec MPEG2
Then used VirtualDubmod to re-convert these to Xvid with a smaller screen and lowered bps settings.

Sorry for off topic, this was the only reason for me to try to upgrade the kernel.

Did you say you have a 3100 Jon? If so I can't help. The latest Cacko for the C3000 (1.23b1) does NOT come with the latest kernel.

Another point I should've re-enforced is that the file on the CF/SD card should be called zImage NOT zImage.bin or anything else. Windows explorer has the annoying 'feature' of not showing files with their extension (like .bin) so if you were to rename the file under Windows it might not work as the .bin might be retained. Use konsole of the Z to check it.

[Jon_J]

I didn't rename it to zImage.bin
I named it zImage
EDIT:
On my windowz machine, I have system files showing and no extensinns are hidden.

Same pb for me three! I think this kernel can not use with Cacko.

[Meanie]

you only need to upgrade the tetsu special kernel if you are running stock Sharp ROM or are using the Cacko beta for C3000. Cacko 1.23 does not require tetsu kernel update because its already included.

it's because cacko 1.23 kernel have no "w100" driver

[Hrw]

w100 is needed on on c7x0 machines

cxx00 machines use bvdd under 2.4

w100 have better performance in mplayer?

Okay, on my C1000, the tetsu kernel just doesn't install. Following the procedure, it tells me to reset the Zaurus. After that it boots - first I thought it was a success - but it turned out that it booted the original Cacko kernel. The installation procedure is a no-op, doesn't change a thing, at least for me.

You can install the tetsu kernel anyway - by replacing zImage.bin in the tools.tar of the Cacko ROM and flashing it. Then the problem described by Jon_J surfaces - launch.conf not found, respawning too fast.

I was messing with the tetsu kernel because the 'Japanese Cacko Kernel 1.23' does not work with C1000 (or C3200 for that matter) and I was under the impression that I need a Japanese kernel for full Japanese support. Other sources now tell me that it may work just as well with the original Cacko kernel for the C1000.

I'm fairly new to all this Zaurus business (flashed Cacko just yesterday), so I'll see if the unmodified Cacko will work for Japanese and get back to getting a Japanese kernel only when I find out that it is actually required
