Angstrom & OpenZaurus / Oz 3.5.4 Not Blanking Lcd
« on: October 16, 2006, 12:40:01 pm »
Is there any word on a work-around for the "Deactivate LCD" option in light&power settings?  I'm running an SL5500 and cannot seem to find any follow-up on this issue (it was mentioned by someone on on the page announcing the initial release of 3.5.4).

General Discussion / Wifi Associates But Does Not Get Dhcp
« on: December 07, 2005, 01:07:47 pm »
We've been testing different AP's here in the lab, so I brought my Zaurus in to help gather data.  Over the last few days we have had a Netgear WGR614 v.6 on the bench which is causing me headaches.  Every wireless card we have tested works with this AP except for my Zaurus.  Even my linux laptop is connecting without problems.  On my Zaurus, iwconfig shows that the card is associated and has a strong signal, but when udhcpc kicks in, it times out and never gets an IP address.

We have been using identical SSID's and wep keys when setting up each AP (verified by the fact that I do not change any settings when I plug my wifi card into the laptop).  I'm not having problems connecting to any other AP's, so I was hoping someone might be able to tell me if there's something different I need to do to try and get a connection here?

Hardware Mods / The Next Step In Customizing
« on: October 25, 2005, 12:20:15 pm »
After a year of using my Z with rubber-bands holding on the lithium battery packs, I'm getting really tired of fighting it.  Ever since I did the battery mod, I've been wanting to mould a new back to cover them up since it's really hard to slip in and out of my pockets now.  I decided to write up a how-to guide as I work on this process.  If anyone has suggestions along the way, feel free to jump in.

So now it's time to get started.  (This is the part where I really wish I had a digital camera, but I'll see if I can borrow one.)  Last weekend I started shopping.  I needed something that was the right size and shape, with smooth rounded corners.  Primarily I wanted something that was the right width, and as long or longer than the body of the Z.  What I found were small transparent plastic cases for holding screws or craft pieces.  These are sold in all different sizes and shapes.  I actually found one that was the perfect size in the fishing lures.

Initially, I was going to just use a dremmel to cut up the case and use it as it is.  But why should I do anything the easy way?    Instead I decided to try my hand at vacuum moulding.  There's a lot of info about this online, and the concept is really simple.  Make a negative, drill holes through it, and connect the holes to a vacuum line.  Clamp a piece of plastic over the top, stick it in the oven, and when the plastic starts to sag, turn on the vacuum to fill your mould.

Last night I found a box for a power supply, lined the bottom and sides with a single piece of aluminum foil, and mixed up a batch of plaster.  The plaster was left somewhat thick, and poured into the box to more than an inch deep.  Then I took my plastic case, covered it with vaseline, and pressed it into the plaster.  You will want to push it in at an angle to try and prevent air bubbles from being trapped underneath.  Get as many out as you can, but any remaning will be filled later.  You will want to press your plastic case in at least 3/4" deep.  Shake and rock it to get the plaster to settle right up against the sides.  You'll need to work fast, as the plaster will start setting up in about 5 minutes.  Note that the plaster will get very warm when it starts to cure!

Once everything is in place, let the plaster sit for at least an hour or two.  It will still be damp, but you want it solid before moving it.  Now you should be able to gently rock your plastic case and have it pop right out of the plaster.  Let the mould sit overnight, then pull it out of the box (either by turning the box over and gently letting the mould drop out, or by cutting the box off).  If you packed the aluminum foil nice and tight against the inside of the box, it should come cleanly off of the plaster.

Now look over what you have.  There may be some air pockets or other defects to fill in.  Mix up some more plaster and fill in the holes until you have a clean mould.  At this point you will need to let the plaster sit for a few days to dry out, but the mould is nearly complete.

What's next:  After drying, the top surface will need to be sanded flat and holes drilled through the mould for the vacuum.

Angstrom & OpenZaurus / Looking For Feeds
« on: October 17, 2005, 10:25:05 am »
It's been quite a long time since I've played with GPE, and now I'm having troubles finding software.  Can anyone point me to other feeds?  Also, is Ipaq software compatible with GPE?  I see a lot of mention of Ipaq in these threads and wonder if there are Ipaq feeds somewhere that I could use.

Some specifics I'm looking for:
- Wellenreiter II
- Firefox or other browsers
- Email client
- working Gaim (the one in the feed has the config screen scrunched up, so I can't see what I'm putting in)

Also I seem to be having problems with ipaq-sleep.  It is being run at boot, but doesn't seem to be using any of the settings in /etc/ipaq-sleep.conf.  The screen goes completely blank after several minutes, but it never dims.  I have commented out the apm line in device_table, but otherwise do not know what else to look for?

Angstrom & OpenZaurus / Multiple Wireless Ap's
« on: October 14, 2005, 05:38:57 pm »
Is it possible under GPE 3.5.3 to configure more than one access point?  Ideally I would like to enter the specific ssid's and WEP keys for my home and work AP's, plus allow conectivity to any open AP's which are broadcasting themselves.  

Wireless.opts would conect to the first block that matched the discovered AP, but I haven't found a similar method of doing this under GPE.  I see that wireless.opts is still present in GPE, so if there is no method for multiple conections already present, can someone tell me if the code to use wireless.opts is at least complete and functional?

Angstrom & OpenZaurus / Wifi under OZ3.5.1/GPE
« on: November 05, 2004, 01:36:18 pm »
I am using a D-Link DCF-660W and have noticed under gpe that when the card is inserted, WLAN0 shows up under ifconfig, however there is no attempt made to connect to a network.  After speaking with Kergoth last night, I realize that this is not the 'proper' way to fix this problem, however I wanted to document that the issue can be fixed without installing any new software, it just requires editing some files.

(Note that everything listed below is done by editing files.  I realize there are some GUI utilities already in place which would do some of these modifications, but I documented everything from the command line.)

Edit /etc/pcmcia/network
 comment out line 66 --> # exit 0
(This line exits the scripts after adding wlan0 to ifconfig.  It prevents the wireless script from ever being called)

 beginning at line 145, add the following block...
(Required because dhcpcd and dump are not present on this build)

Code: [Select]
elif [ -x /sbin/udhcpc ]; then
    log "/sbin/dhcpc -f --interface=$DEVICE & > /dev/null" || exit 1

edit /etc/pcmcia/wireless.opts
(This can also be set up from the WLAN config, or the network config utilities)
Code: [Select]
    case "$ADDRESS" in

edit /etc/pcmcia/network.opts
(Also can bet set up from the network config utility)
Code: [Select]
After making these changes, I was able to successfully connect to my WLAN, pull DHCP info from the network, and ping out to the internet.  The connection is noticably slow - it takes about 10-15 seconds to actually set everything up, but at least it gets me online until the OZ team is able to put out there next release.

Angstrom & OpenZaurus / Fix for timeclock reset
« on: October 25, 2004, 12:41:15 pm »
Just an FYI for anyone still suffering from the zaurus internal clock resetting every time you reboot.  The hardware clock needs to be manually set before it will start keeping time, and whenever you reboot the system clock is reset to the hw clock.

- Manually set the clock (either through clock settings or by pulling from an online source)
- Go to a command prompt and issue the command "hwclock --systohc"

This was tested under OZ3.5.1 on an SL5500.

Angstrom & OpenZaurus / zRoadmap help under 3.5.1
« on: October 25, 2004, 11:39:49 am »
I currently have zRoadmap 1.0-2 installed, using the compat libs.  Roadgps is picking up my serial digitraveler, and shows black and white bars for several satellites, yet roadmap won't get a fix on my position, even with 4-5 black bars.  If I do a 'Find GPS Position', it goes off my map, and the direction of travel never changes

Last week I thought I found zRoadmap 1.0-3 which was compiled by mickeyl for 3.5.1, unfortunately I downloaded it to my SD card right before I wiped everything this weekend, and I can't seem to find the URL again.  Does anyone know where I can find this or some other .ipk of zRoadmap compiled for 3.5.1?  I'm not sure what else to try, because I didn't have these problems under 3.2 (running zRoadmap 1.0-2).

General Discussion / Compact Flash socket info?
« on: October 21, 2004, 05:23:15 pm »
I've been trying to find a sample schematic of how a 2-slot compact flash connector would be wired.  I am assuming there are 1 or 2 lines specific to each connector that act as an enable for the card plugged into that connector, but I can't seem to locate what I'm looking for.  Does anyone know specifically which line(s) act as the enable on a setup with more than one socket?  Would it simply be a matter of connecting all the other lines directly from one connector to the second, using a seperate enable line from the controller chip, or is there something more to it than that?

Site Suggestions, Requests, and Updates / How-To forum(s) ?
« on: October 20, 2004, 04:41:35 pm »
What about forums for hardware and software how-to's?  Perhaps a seperate one for each subgroup (5x00, C7x0, etc), but it might be nice for those looking to hack their Z to have an easy place to find articles.

Posting guidelines for these groups -- These should not be requests for how-to's, but actual articles.  The poster should try to include complete step-by-step information on how they accomplished the goal.  If there is a single how-to forum then the title should state if it's a hardware/software hack and what models of Z or what rom version the hack was based on.  Questions could of course follow the original post, and anyone coming into the discussion later would have a single source for the original info plus all feedback including problems encountered.

5x00 Hardware / Custom battery pack
« on: October 14, 2004, 03:54:16 pm »
OK I'm getting way out in left field here, and since I have a spare Z with a busted touch-panel to experiment on, I'm not too concerned about just jumping in and trying it out.  HOWEVER... if someone can see any immediate flaws in my <evil> plan, feel free to jump in and point them out.

With that out of the way, I recently ran across the Sony #LIS2106 battery pack.  It is 2.75" x 2.46" x 0.15", 3.7V li-ion, 1300mAh.  Ideal size to strap to the back of an SL5x00, and it's the same type and voltage as the original battery.  950mAh + 1300mAh = 2250mAh.     Find the + and - leads, tie them directly to the internal battery (of course the cover would have to be left off, but would be covered by the new battery).

Only one issue I see here.  Will the internal charging circuit of the SL5500 deal with the extra capacity?  The way I see it (and I've been wrong before), tying both batteries together in parallel should safely work with the charging current provided, but of course it will take more that twice as long to recharge.

Assuming this crazy scheme would work, it appears you could actually fit TWO of these battery packs on the back of the Z for a total of 3550mAh, while increasing the overall thickness by a mere 0.15"/4mm, and the weight by 2.3 ounces/65g (again,   )

With the considerable increase in battery power, this may be a worthwhile mod even if I have to use an external charging method for the additional batteries.  Comments or suggestions?

Angstrom & OpenZaurus / Problems flashing OZ
« on: February 17, 2004, 01:32:10 pm »
A friend asked me yestarday about flashing his SL5500 to OZ3.2.  I still have the files on my CF card from flashing one of my Z\'s recently, so I brought the card in today for him to use.  

First problem: The flashing process stops after less than a minute, rather than taking the normal amount of time to complete.

Second problem: After resetting and rebooting, he is getting the opie logo, followed by multiple lines of errors, most complaining of bad tar headers.

We tried re-flashing 3 times, with no change in results.  His system was recently flashed to the Sharp 3.x image with no problems,  and he has had no previous problems using his Z.  I will check the files on my CF card tonight, but as I said I have recently used the files on this card to flash another system.  I have not been able to find any previous mention of bad tar headers after flashing a system, so I would appriciate any suggestions to help get his system up & running again.

Angstrom & OpenZaurus / Wireless automounting
« on: December 26, 2003, 03:22:00 pm »
What does it take to automount a share when you connect to a particular wifi network?

I am using OZ3.2 on an SL5500 with a D-link 660

I tried modifying /etc/pcmcia/wireless.  It appears to fire correctly when I insert my card, and I can filter mounts by SSID, but the smbmount command will not work within this script.  I verified the IF loop is working by touching a file.  I\'m not seeing any error messages.  I also tried using the full path to smbmount.  The same line works correctly from the command line, so I\'m not certain why it doesn\'t work within the script.  

The only possibility I can think of is a timing issue... perhaps the wireless isn\'t ready to use by the time smbmount tries to run?  I don\'t know, but any suggestions would be appriciated.
