Overclocking The C3000

[totsubo]

I've read the C3000 can be overclocked. I went and installed the overclocking applet but when I run it, a screen comes up that says please wait, but then nothing and the normal desktop returns.

Do I need a special kernel installed in order for the overclocking applet to function?

[ThC]

you'll need a special kernel from Here (wich will also display boot up sequence and include some patches about pen pressure detection and more ...)

Thanks, I'd already found this link but I can'tunderstand the procedure for actually installting the kernel.

Something about putting installer.sh on CF/flash card is as for as I got.

Do I need to first d/l the sourcce to another machine and then patch it with each patch? (all 16 of them?)

The google translated instructions are hard to follow. Is there another place where I can find english instructions?

Thanks!

nope... well as far as you do not understand how to do this i believe you wouldn't want to enter such things as configuring kernel, patching it, and cross-compiling it... there is an image of the new kernel already compiled... it's here
1- download it

here are my 2 cents

2- download the updater.sh

3- you can check the md5 sums to see if your download went well... because if your file is corrupted you'll be in big trouble i believe
to do this, on a linux box you just have to

Code: [Select]

$ md5sum zImage-v17f-C3000.bin and compare the result with this page

4- you need a blank, vfat formatted CF or SD card. a small one like 16M is enough to put the kernel and updater.sh.
copy the file zImage-v17f-C3000.bin to your CF/SD card naming it zImage (small z big i)
copy the file updater.sh.c3000 to your CF/SD card naming it updater.sh
i personnally did a

Code: [Select]

chmod a+x updater.sh (i don't know how the evaluation of updater.sh is made in the flash process)

5- follow the instructions about installing pdaXrom... here are mine (as i  can recall)
    0) put the CF/SD card is its slot
    1) be sure you Z is not connected to AC power
    2) unlock the battery cover, remove the cover, remove the battery for at least 5 seconds (go and have a coffee   )
    3) put the battery back in, put the cover on and lock it
    4) put the Z on AC power (unless it won't work)
    5) press and hold the 'OK' button
    6) switch the power on
    7) a maintenance menu with 4 entries appears, go in the last (4th) one.
    you then have 3 options (1. CF, 2. SD and 3. back)
    9) select your choice, a confirmation appears, move to the left button (Y) and click ok
the screen switches off and nothing seems to happen for a few seconds
then a message comes up

Code: [Select]

kernel update
zImage:1244096bytes
please reset     10) do 2) and 3) once again to reboot your Z
then you should see the booting messages as in every linux box and the small pinguin.

There is a gui-clock changer but i've not used it.
Once your Z is up you are able to overclock it using special values :
the value in /proc/zaurus/CCCR determines the frequencies of processor and screen
values for C3000 are
# 2000210: CPUクロック416MHz システムバス208MHz (default)
# 2000310: CPUクロック624MHz システムバス208MHz
# 2000214: CPUクロック520MHz システムバス260MHz
# 2000218: CPUクロック624MHz システムバス312MHz
the value in /proc/zaurus/VCORE determines the VCORE voltage used
values for C3000 are
# 0a: 1.350V (default: 416MHz時の定格)
# 0c: 1.450V (520MHz時の定格)
# 0e: 1.550V (624MHz時の定格)

just do a

Code: [Select]

echo value > file to change a value.
be sure that your VCORE is ok before changing the freqs.

i've used the fastest for about 10 minutes running X/Qt + debian with an x-term, a terminal, thunderbird, firefox and the Qt Calendar and the screen froze (it was flickering). (reset needed). I've also used value "2000310" and it works fine.... but it drains more power for the battery...

i've used the infos given by m-morino in this thread and infos found on this site

i was hoping to get kino2 and mplayer-bvdd to work but had no chance with this last one...

i'm a user and not a master in Z3k matters so don't wait too much from me if this does not work as expected... you're alone with your responsability to do this or not...

Thanks for the really detailed instructions!

I'd luckily found a page with similar instructions at:

http://www.steyla.com/zaurus/kernel.php3

And was able to take it from there. The info you provided though is much more thorough

Everything went fine except that I still get the regular Sharp boot up screen followed by the CG Silicon one. I don't get any Linu boot sequence messages.

I also can't get the overclocker to work. When I try and start it up I get a whiet screen with "Please wait" but after about 10 seconds the main screen re-appears.

I'm worried that I didn't install the kernel properly b/c when I do a uname -a I get this:

Linux Zaurus 2.4.20 #1 Thu, 28 Oct 2004 09:59:43 +0900 armv5tel unknown

I thought the newest kernel (P16?) should be at dated least  2004/12/23 no?

i bet your procedure did not get well...

you should have

Code: [Select]

Linux zaurus 2.4.20 #1 Sun, 26 Dec 2004 19:22:06 +0900 armv5tel unknown
that's why you're not able to overclock

Just some more information. After I installed the new kernel I get this message:

--- Zaurus SD updater ---
Please reset

No mention of the image size. Is that normal?

[totsubo]

Hum .... I checked the md5sum and it was ok

What could I have done wrong?

[darkloran]

What could I have done wrong?

well, trivial check... have you put your files on a SD card or CF card ?

can you do

Code: [Select]

ls -lh /mnt/card if it is an SD card, to check the names of files and size and permissions ?

[totsubo]

I re-read your instruction and saw that I forgot to rename the image file to zImage

I just did that, put the Z in suspend and then took out the battery and waited 10 seconds.

I then put the battery and the power cord back in and now I can't restart my Z.

No lights come on or anything!

can you check the "lock" on the battery cover
=> it should be on the right when you can read the "Zaurus" in the right way

can you remove and place the battery back once again, i had such a problem once because the battery was not "exactly" as it should... a great anxiety came up...  

[totsubo]

Finally! After much fiddlig with the battery I got my Z to start! Now to try installing the kernel again.

Do you think that renaming the image to ZImage was the problem?

good... i know how "playing" with this Z is a big source of anxiety... will i do this or that... what ? what ? where has this light gone ? ...  

Do you think that renaming the image to ZImage was the problem?

sure !
by the way it should be "zImage" and not "ZImage"... i don't know what you've put last... but check again, i've said :

small z big i

[div align=\"right\"][a href=\"index.php?act=findpost&pid=67476\"][{POST_SNAPBACK}][/a][/div]

It on SD and the ls gives:

i've read somewhere that there should only be zImage and updater.sh on the card.
anyway, your names and sizes are ok
