C1000/3x00 General discussions / Please Help! C3000 Almost Gone

« on: August 04, 2005, 06:10:06 am »

But this did not solve my initial problems   :
- On/Off button not working, meaning that after a suspend the only way to awake the Z is by inserting or taking the power plug
- the maintenance menus are frozen (no answer to touchscreen or keyboard)

Any help will be most welcome!
[div align=\"right\"][a href=\"index.php?act=findpost&pid=90533\"][{POST_SNAPBACK}][/a][/div]

Can anyone with a C3000 provide me a listing of all the files in the rescue Linux?

It can be obtained by booting with  the D+B keys, logging in as root, inserting a memory card (say CF) and executing
ls -lR > /mnt/cf/listDB

The file istDB in the card will hopefully help me in finding what files my Z is missing...

Thanks in advance!

I have the Qtopia environment running but I still cannot use the maintenance menus (either  resetiing with D+M or with Ok) because there is no answer to the touchscreen nor to the keyboard.

What can I do???

The commands I mentioned in my last post were adapted from the rc.rofilesys script. Is there a script for the NAND restoration somewhere?
[div align=\"right\"][a href=\"index.php?act=findpost&pid=90144\"][{POST_SNAPBACK}][/a][/div]

Here are a list of things I have done successfully even without the maintenance menus:

- installation of the TriSoft C3000-2004-12-23-12-40 backup
- manual update of the Sharp ROM to version 1.11 (see below for the details)
- installation of the TriSoft C3000-2005-03-18-12-30-DEkbd-EN.zip backup (that should not be installed on C3000's running 1.01 ROMs!!!)

But this did not solve my initial problems   :
- On/Off button not working, meaning that after a suspend the only way to awake the Z is by inserting or taking the power plug
- the maintenance menus are frozen (no answer to touchscreen or keyboard)

Any help will be most welcome!

Instructions for the manual update of the Sharp ROM to version 1.11 (at your own risk!):

- in your PC
-- get the update archive from the Sharp site
-- unpack it (I used lha in Linux but cannot reproduce this step...)
-- copy the files to a CF/SD card (root directory, VFAT)
- in the Z
-- reboot while pressing the D+B keys to enter the rescue Linux
- log in as root
- insert the CF/SD card and execute:

Code: [Select]

mount
 # so that you can see the mount point for the card; mine was  /mnt/cf
 # decode updater script (this is done replaces the coded original)
/sbin/decsh /mnt/cf/updater.sh
 # run it and pray...
/mnt/cf/updater.sh /mnt/cf
 # if all goes well, there will be 3 "Success!" messages
  # reboot
reboot

C1000/3x00 General discussions / Move /home Dir

« on: August 02, 2005, 07:42:10 am »

Did anyone try to move the /home dir to a different location?
The 5 Mb limit is a bit frustrating.

Can it be moved to the internal disk without triggering a lot of problems due to the fact that this disk is not available when booting?

Hi,
It seems this cannot be done for the C3000: have a look at

If you can get into the D+B rescue mode then you have to mount the "normal" partitions before you can do any work on them. D+B mode gets you to the hidden filesystem on mtdblock1 (or possible mtdblock0). The normal partions are mtdblock2 (root) and mtdblock3) home - at least that is true for the C760 and C1000 zaurus.
[div align=\"right\"][a href=\"index.php?act=findpost&pid=89919\"][{POST_SNAPBACK}][/a][/div]

My C3000 is back thanks to the information above! Many thanks Stu!  

All I had to do was to enter into Linux using the D+B key combination and then execute the commands that are listed at the end of this message.

When rebooting there was one or two error messages (too fast to be read) but then the Qtopia environment started fine.

However the On/Off button is still not working    I intend to upgrade to the Sharp 1.1 NAND and see if it works.

Thanks for all the help!

[CODE]
cd /
mkdir x
 # this is the root of the normal file system
mount -o rw,noatime /dev/mtdblock2 x
x/sbin/eraseall /dev/mtd3
mount -o rw,noatime /dev/mtdblock3 x/home
cd x
tar xf root/.home_default.tar
 # prepare /x/dev
dd if=/dev/zero of=dev/ram1 bs=1024 count=64
mkfs.minix -i 512 dev/ram1 64
mount -t minix dev/ram1 dev
(cd home ; tar cf - dev | (cd /x ; tar xf -))
 # mount /x/tmp
mount -t tmpfs -o size=1m none dev/shm

Here are the relevant config settings that are needed for mounting jffs2 images

[code]#
# Miscellaneous filesystems

CONFIG_JFFS_FS=m

[div align=\"right\"][a href=\"index.php?act=findpost&pid=89989\"][{POST_SNAPBACK}][/a][/div]

Hi Stu,

Thanks! I am not at home now, but yesterday I could not find any entry for JFFS2 in this section of the 2.6.12.1 kernel in my PC. I downloaded now the 2.6.12.3 source and checked that these options are there indeed. So I will probably have to upgrade to 2.6.12.3 at home.

Thanks again!

Hi Stu,

Thanks a lot for your help!

Mounting /dev/mtdblock2 on /mnt I could check that /mnt/root/.home_default.tar is there and intact. I also checked that /dev/mtdblock3 has the /home file system. So, I think I will manage to restore the original setup. I will try to do that tomorrow and will post the result.

All you need to do mount the initrd on a linux machine using something like this

Code: [Select]

modprobe mtdram total_size=65536
modprobe mtdblock
dd if=initrd.bin of=/dev/mtdblock0
mount -t jffs2 /dev/mtdblock0 /mnt/floppy
Just remember that the filesystem you boot into using D+B IS NOT the regular filesystem the zaurus uses.

Stu
[div align=\"right\"][a href=\"index.php?act=findpost&pid=89922\"][{POST_SNAPBACK}][/a][/div]

I tried this but my 2.6.12.1 kernel in the PC had no support for MTD. I reconfigured it but got stuck: no mtdram module, and no support for the jffs2 file system type (from /proc/filesystems). What are the kernel configuration options that must be selected?

Thanks again!

I have been asking here for a copy of the original Sharp /root/.home_default.tar so that I can try to restore my C3000.

As I got no positive answer will anyone be so kind as to provide me with a listing of this tar file? It can be obtained by typing the following in a Linux shell:

tar  tvf  /root/.home_default.tar  >  hdefault.txt

The listing I need will be in this  hdefault.txt file.

The listing of the tar file of a C3001 instead of a C3000 may help.

Thank you very much in advance!

You can find a decoder for the NEF format and information on applications using it here
Raw Digital Photo Decoding in Linux

As my Z is half broken I cannot try them out myself ...

Thanks for that, do you know if there is a version that's already compiled because I'm not familiar with compiling source files.
[div align=\"right\"][a href=\"index.php?act=findpost&pid=89255\"][{POST_SNAPBACK}][/a][/div]

No I don't know about a compiled package. In order to compile dcraw you need to have the JPEG library (I cannot say if this is available for the Z) and of course gcc (that is part of the Linux in the Z). Then you simply type gcc -o dcraw -O3 dcraw.c -lm -ljpeg in a shell (terminal window) and you get the executable under the name dcraw.

Maybe other people with live Zauri may give more info on this.

What makes you think you cannot access the maintence menu?
[div align=\"right\"][a href=\"index.php?act=findpost&pid=89264\"][{POST_SNAPBACK}][/a][/div]

I can see it, but I cannot use it as there is no answer to key strokes or to touching the screen with the pen. Probably there are Linux devices missing as the /home/dev directory was wiped out.

Any idea on where I can find a copy of the original Sharp /root/.home_default.tar ?
I have tried to rebuild /home with the Trisoft backup but this failed. I think the reason was that there are symlinks missing there,.

I love reading these threads, because when and if(yea right lets just omit the if) I screw my 3100 up, I will need to know there is a solution out there. Perhaps if you removed the hdd and used another computer to restore the data from a backup(from trisoft or streamline, then put the hdd back in then maybe that would fix it, just logically thinking this one out

You may be sure I will try hard to devise a solution you may use in the future! I will post it, that is if I find one in the first place  

There is no need for taking out the hard drive: I can access it, it is in good shape apart from the /home directory and I can use the CF card to import files. In order to proceed I really need the original Sharp /root/.home_default.tar file, but I don't know if the C3100 one is identical to the C3000's.

Thanks for the advice.  I can view JPG no problem, but I can't view NEF files (RAW images taken when using digital SLR cameras).

Any other ideas?

..menu of the update.. when opening back, resetting, and turning on power while pushing the OK
button.

Because only the content of hdd1 changes places, hdd2 and hdd3 are safe.

I will recommend it as one choices.
[div align=\"right\"][a href=\"index.php?act=findpost&pid=89195\"][{POST_SNAPBACK}][/a][/div]

Thanks for your help!

The  'Power On'+Ok combination is also not working, probably because the power button is in some way disabled (this was my initial problem).

So, with neither this nor access to the maintenance menu (using the D+M reset) I think there are only two solutions, both using the Linux shell:

1) running the updater shell script to install a new ROM; I don't know if this is feasible

2) restoring the missing files in the /home directory and restoring the /hdd1/.sys/hdimage2.tgz; I have this tgz but I don't have /root/.home_default.tar that is needed for restoring /home. Would it possible for you to put a copy of this file somewhere for me to get it?

Cheers.

I think the easiest method of the return to the state that had just been bought is to update it
with ver1.11JP ROM .

Please go to this URL of Sharp.

http://support.ezaurus.com/sl-c3000/update...0updatecard.asp

And, please download card_update_3000111.exe.

The following files appear when double-clicking.
・initrd.bin（4,337KB）
・zImage.bin（1,264KB）
・mversion.bin（16KB）
・updater.sh（7KB）
・hdimage1.tgz（19,734KB）

Rom is only usually renewed with SD card or CF card.

 Luck.

Many thanks, but unfortunately I cannot access the maintenance menu as described in my previous messages.

I found out that the following file is missing in my C3000:

/root/.home_default.tar

Can anyone provide me a copy of it? I don't know if it depends on the NAND version: mine is Sharp 1.01.

I thought mine was gonna make a trip back to Japan after I loaded an unstabled OZ version.   This site got me back from scratch...!

http://www.xlfag.com/zaurus/

Thanks, but as I cannot use the maintenance menu I cannot follow the instructions in that page.

Does anyone know if it is possible to install a NAND image directly from the Linux prompt?

Please help! It seems I am about to loose my C3000 for good...

After installing Debian, the on/off button stopped working. Unfortunately I did not a backup before the Debian installation so  I tried to install the trisoft backup but the Z made a reset and on next reboot showed the progress bar and then came to a standstill.

Currently I can use the D+B trick to get into Linux but the home directory is empty and rebooting shows the Sharp logo, some messages too fast to be read at the bottom of the screen and gets stuck. I tried without success to rebuild the home directory by hand from the trisoft backup. All partitions of the hard drive are ok.

When trying to flash the NAND, I start with the D+M keys and get the maintenance menu but there are no answer to keys or the pen on the touchscreen.

What should I do? Is there any point in trying to reinstall any files, and if so where may I find them?
