Is there anyone out there up to the task of breaking open an SL-6000 battery, replacing the worn-out cell with a fresh one, then putting it back together?
17 Jan 2006
Thanks C-Guys!

I was poking around the driver for their WiFi card to investigate something. Then, I realized that they completely replace the sharp_sdmmc kernel module with their own SD/SDIO stack. So just for fun, I installed it and surprise, I can now read, write, and mount a Sandisk 2 GB SD card. So far, it's been working very reliably.

Now, the catches:

1) It works fine on my C760 (running Cacko 1.12). But, when I tried to install the modules on my 6000, I got kernel oopses. So, it may be very sensitive to the model/kernel that is running. This is not that surprising since C760 is one of the few models listed as supported on their website.

2) vfat filesystems are fine. I had some problems with ext2. I fixed it by reformatting my card with "mke2fs -b 1024 /dev/mmcda1". This driver doesn't seem to like block sizes > 1024.


Anyway, if you want to repeat my experiment, just download and install this ipk, and reboot the Zaurus:

Is there a different feed I should be using besides http://cacko.biz/cacko/feed ?

Because, many of the packages don't work. Here is a partial list

Using Cacko 1.23 light: Opera wouldn't install, and Netfront installed, but segfaulted.

Fortunately these programs work correctly when I reflashed with Cacko full. So much for the nice idea of using light.

But other programs from the feed didn't work:

libSDL, libSDL-mixer, and Doom. Doom segfaulted. I replaced the libSDL and libSDL-mixer with the ipks from zports, and then doom ran, but the display was sideways. Finally, I uninstalled doom-engine.ipk and replaced it with prboom.ipk from zports and all was OK.

There were also some others I tried that failed, but I don't remember at the moment what they were. I'll post back later with details.

Has Cacko stopped supported the C7x0? It seems like I shouldn't have to use other ipks for programs that are in the feed, otherwise what's the point of the feed?

The server seems to be responding a bit slowly right now, probably because everyone is downloading the new release?

Why not use BitTorrent for the big files (release images, feed.tar.gz, pdaX86, etc) and just use http for the feeds?

It will make everyone download faster, save you guys $$$, and it provides automatic mirroring in case the server fails again.

Think about it.

I was screwing around with the flash memory, and bricked my Z so hard that it wouldn't do anything except flash the mail and power LEDs. None of the special boot sequences I know worked and I couldn't get to the NAND restore, or any other restore procedures I knew of.

I looked around for solutions in vain, and I was getting to box it up and start the long round-trip to Japan, when a lucky set of Google search terms came up with an idea. I tried it, and it worked.

Since the page I found is only in Google's cache of the dead externe.net forums, I'm going to copy it here for posterity.

I have the solution!!! I am so happy now!!! I was surfing for hours and hours, and playing with binary files and dd...

But I found a website that has the solution for my device: http://www.piro.hopto.org/~piro/pukiwiki/p...B%5BP2ROM%5D%5D

I pushed FN+D+M while connecting the AC power, and suddenly I did have a Service Menu!

Now I'm trying to restore a c860 NAND from www.trisoft.de.

Everybody thanks!


I'm also going to copy a translation of the Japanese WiKi page. smile.gif It seems to have a very complete description of special ways of booting.

Because it was possible to revive with NAND RESTORE here when FLASH in zaurus has been crushed before, let's write the thing that it did around here or the doubt and.

It is a thing of the reference as for the page above. Moreover, I will read the page of 59414D41 Mr. to whom the page was written.
It is considerably important and comprehensible.

By the way, the thing done after it determines it of act of danger considerably. The responsibility cannot be taken no matter what it happens.
It had already been destroyed, and this act was able to be eased for me.
By the way, only SL-C700 is confirmed.

How for start-up of debugging menu.

Basically, it stands up by turning on the lock switch of the battery lid while pushing some keys.
Moreover, it is acceptable even if it pushes at the restart. The battery is removed, and it is OK to do the adaptor in while pushing the key.

Oh dear the around here person ..NAND FLASH BACKUP.. thinks with diag menu.

C750 ..kernel.. is seen and doubtful reset_key_combination ..corgi_logkey.c.. is discovered.
Fn+Home, Fn+P+D, and Fn+M+D are recorded anything doesn't happen though it tentatively confirmed not recording up.
Can only SL-C750/760 be done because it is not in the kernel of SL-C700?

Destruction and restoration of NAND device

/(mtdblock2) was not able to be read for a moment suddenly ..the former kernel and...
Oh dear, it is generated the error while writing it when thinking the furnace as soon as reconciling when initrd.bin is rewritten.
At this point, the debugging menu ..information.. worries .... considerably. Including thing sent to repair

And the net are variously examined and the cod and the debugging menu are discovered to be. (..piling up.. did not only read ..ー.. neatly. )
When it boots with DB by the kernel for debugging, and mtd2 was done in the mount, writing is improper though it is possible to read somewhat for the time being.

NAND is backed up with diag menu though it is first of all broken in the said thing. Can it become calm a little because it considerably drives it at time the other day?
Error generation in restore though it manages to obtain SYST700.DBK, and restore is done. At this point, it considerably becomes blue.
The thing that restore can be done confirms the backup goods of NAND of broken, and NAND FLASH(FULL) is executed for the time being. The resignation mode around here considerably.
Restore can have been done by doing SYST700.DBK ..obtaining.. in restore. It is a considerable state of the excitement here.
It was possible to finally revive.
Thank you for information about 59414D41 Mr..

Choi at about half a day at this period.

However, restoration was very because my system had been completely customized.
When a considerably steady system can be done, one degree NAND FLASH BACKUP.
However, it is ..painful.. to take time to back up. For about one hour(With SD. )

9/15 postscripts

It has understood well and a postscript is added when fiddling with this while ..the.. output.. seeing making the cereal cable somehow. The cereal cable was connected directly troublesomely though had when seriously making it by using MAX3222 first.

The thing that tentatively entered boot and the maintenance mode can have been done though MAINTE and DIAG of C750 were incidentally put in C700. However, it seems writing in P2ROM and a furnace around here with SL-C700 on the screen of the maintenance mode because it goes out.
Even if reset hanging when the battery lock locks also replaces MAINTE, it is put on P2ROM, and it is hardware or might be either. a kooky bowl Because the advantage doesn't exist maybe even if MAINTE of C750 is put, either it is not worth putting it.
