5x00 General discussions / 5600 - Factory Flash - Frowny Face

Wow, I posted too soon.  In the past when I had tried the Format option it did nothing, but apparently it actually worked this time.  All this time I thought I could never get it back to it's factory default...

While trying to reset my Zaurus back to the factory defaults, after the Sharp "Please wait 2 minutes" screen, it bails to a console and constantly repeats:

ERROR: /usr/sharp/etc/launch.conf -- can not open file
/sbin/launch : launch.conf not found
INIT: Id "ln" respawning too fast: disabled for 5 minutes

Not really sure what to do from here.  Thanks for any suggestions.

General Discussion / Wireless fails to obtain IP

« on: September 18, 2004, 10:50:45 pm »

My SL5600 with AmbiCom CF wireless card works great when I float around the wifi on my local campus, however, when I try to connect up to my dlink at home I run into some problems.  My home network is setup to use 128bit WEP, MAC filtering, and I have an SSID set.  I have entered my wifi cards mac address into the dlink like I would any other computer, and when I setup the networking options and configure the wireless it actually sees my network.  The problem is the fact that it can't seem to grab an IP address, and that is throwing me off.

If anyone could nudge me in the right direction, I would greatly appreciate it.

Angstrom & OpenZaurus / Changing filesystem install?

« on: March 24, 2004, 08:38:25 pm »

Right now it\'s a tad rediculous installing OZ 3.3.6-pre1 and having it use up a ll but 500k of space on my root disk on my 5600.  Is there, or will there be, a way to allow it to install across both internal disks?

I\'m noticing this the most when I try to install apps to the empty disk, but the root disk continues to fill up for various reasons.

Angstrom & OpenZaurus / Completely removing Sharp ROM?

« on: March 19, 2004, 06:58:15 pm »

Hey guys,

I\'ve installed both 3.3.5, and 3.3.6-pre1.  There are a few quirks right now, such as the screen bumping and clock reset on reboot, but beyond that I have been extremely satisfied so far.  I am running 3.3.6-pre1 at the moment.

The process of installation boiled down to:

Drop the initrd.bin, zImage, updater.sh files onto a cf card.
Remove battery cover, hit reset, replace cover.
Plug in AC.
While holding down the OK button, power system on.
Select the Update function from the maintenance menu.
Select CF card option, say Yes.
After it says installation complete, turn off unit, remove battery cover, hit reset, replace.

The system will boot into Opie, and ask you a few questions about time and whatnot.
Skip those steps!  Just accept what is there for the moment, and get Opie booted.
Go to the Application tab, and open Konsole.
Type:  echo 1 > /proc/sys/kernel/printk
(The above step removes the screen bumping issue).
Edit /etc/init.d/opie and around line 42 add the above echo line.

After this, change your system appearance to taste (I prefer 8 point font, more readable), and set your system time.  Just keep in mind that anytime you do an actual soft reboot the time will reset (haven\'t found any fixes for this yet).

From here on out things have been a snap for me.  I cleared out the /home directory, which had a bunch of old and redundant Sharp ROM information that was wasting space.  I the mapped /home in the Packages utility as a drive in which to install to (the root partition was down to 500kb of space), and then removed packages I felt comfortable removing from the system using the Package utility bringing me up to 1.3mb of free root partition space.

My AmbiCom WL1100C-CF wifi card works out of the box, mostly.
 
Stop/Restart the service from the Network menu (I chose the Auto mode in the Configure tab for the wlan0 device as well).  If a network is in the area it will load it up, (and I am assuming you can specify the SSID of a network otherwise).  The WEP keys work fine as well.
The annoying wifi steps I have to do to get the network gateway running (from Konsole) are:
udhcpc -i wlan0
route add -net default gw 192.168.0.1 netmask 0.0.0.0 metric 1 wlan0

I wrote a quick bash script (in a meeting no less, hurrah) to make the above a little easier.  I\'ll tweak it more a little later to automatically set my gateway based on the discovered network instead of manually typing it, but the following works for now:

Code: [Select]

#!/bin/sh

udhcpc -i wlan0

route add -net default gw $1 netmask 0.0.0.0 metric 1 wlan0

Just chmod +x the file, and call it as ./file.sh <wireless_gateway_ip>

I\'m sure there\'s an easier way, but this is what I have been doing.

I can\'t take full credit for any of the above, I found this link which gave me several hints.

From here on out, I\'ve been using it for daily routines.  Calendaring, notes, eBooks, etc.  The battery life has been exceptional, and even tinkering with the wifi card all day (on and off) dropped it down to 50% by the time I got home.

Today I\'ve been trying to find some way to get X11 running on the unit.  I\'m not inclined to start making any of my own builds though, so I\'ll just continue to hunt down projects and try them out for the time being.

Angstrom & OpenZaurus / Completely removing Sharp ROM?

« on: March 17, 2004, 03:25:11 am »

Have you made any progress in getting rid of those old Sharp directories?

After a little searching around I finally figured out what OZ does.  The Sharp ROM stores most of your independant application and file data in /home (located on /dev/mtdblock3), so by actually removing all that I wasn\'t really harming anything except my own data and a partial chunk of the Sharp ROM filesystem.  I also believe that I was referencing said partition through the OZ package manager incorrectly (I couldn\'t seem to write to it my first couple experiments), thus leading me to believe that I had either installed OZ wrong, or that Sharp kept pieces of itself around for a reason.

I now have a working install of OZ again, but this time I am armed with a more thorough knowledge of how it is laid out on the disk.  The initial install goes to the first 32mb partition as the root / partition, and /home goes on the other 32mb partition.

What threw me off when I was trying to reflash the Sharp ROM was the fact that it kept retaining all my data (located on the untouched /home partition).  This in itself is disturbing however, since I would expect the Format option in the maintenance window to literally wipe the unit clean, or OZ to delete the data.  I have come to find out, however, that OZ never touches the /home partition when you install, and I still haven\'t figured out why Format doesn\'t actually wipe the unit.

The only thing that is still bugging me right now though, is the fact that I cannot get a Sharp ROM reflashed correctly.  Now that I have a working installation (and again, knowledge) of what OZ does on the other hand, I\'m not as interested in getting that working since the only issue was my head

Security and Networking / Cisco LEAP software?

« on: March 16, 2004, 09:17:14 pm »

I\'ve googled a little, and am under the impression the answer is \"No\", but one can never be sure.  Is there a package that has a Cisco LEAP client for wireless networks?

Sharp ROMs / Complete restore ROM?

« on: March 16, 2004, 03:58:56 am »

This is exactly the answer I was looking for, but this post is the same thing I ended up doing.  I still haven\'t figured out how to flash back to a complete Sharp ROM (if that is possible?), but the linked post does answer a few questions that were tugging at the back of my mind.

Sharp ROMs / Complete restore ROM?

« on: March 16, 2004, 02:33:15 am »

I am trying to replace the system on my SL5600 due to a little reckless experimentation, but am having trouble finding the correct ROM to replace the entire system back to a factory build.

Formatting doesn\'t seem to do what I want (i.e. replace files that I \'experimentally deleted\'), and I get the impression that the 1.32c update ROM isn\'t the \"replace the entire system\" ROM, since my system still doesn\'t boot completely when I drop it on.

The good news is that I can still run OZ, but it is now apparent that it never actually replaces the Sharp ROM (waste of space?).  Still, I would like to know that I can resort back to a factory fresh Sharp ROM at any time.  Suggestions?

Angstrom & OpenZaurus / Completely removing Sharp ROM?

« on: March 15, 2004, 02:35:39 pm »

I recieved my new SL5600 on Friday last week, and after tinkering around with the default OS I naturally went on to flash it with OZ.  After applying the various fixes to get things working right, I definately liked what I saw, except for the fact that /dev/mtdblock3 was unwritable.  That\'s too much free space to be giving up, I thought to myself.

Over the course of the weekend, I flashed back to the Sharp ROM, but much to my suprise noticed that all the apps/files/notes I had made were still intact.  That struck me as extremely odd, as I had thought that the ROM would have been overwritten by OZ.

More experimenting led me to believe that the Format option under the maintenance menu did absolute nothing.  No matter how many times I used it, it never went back to a \'factory level install\'.  I also attempted reflashing several times in a an attempt to get a factory build.

Here is where I probably made a mistake, although if it is a mistake I think it should be correctable.  I deleted all the contents of the /home directory (/dev/mtdblock3), then attempted to Format/Update my unit.  Curiosity gets me into trouble as usual, and after the kernel booted the system would never come back up.

Fast forward to now.  I have installed the OZ ROM, and it works as I had assumed it would.  I am under the impression that whatever pieces of the Sharp ROM are floating around will still remain there, using up valuable memory I could be devoting to OZ.  This seems very annoying to me, but I am also assuming that I may have done something wrong along the way (besides the obvious).  Is there a way to completely remove the Sharp ROM, or for that matter completely replace what I have broken?  If not, this would seem like a serious design flaw.

Overall I like what I have seen so far, so I\'ll keep tinkering with this over the rest of the week.  Thanks for any input.
