Re: Maemo Mapper v1.4 for 770/N800
 

I have upgraded to the latest version and downloaded the repositories from the Maps dialog to replace my old ones, but I don't see anything about OpenStreetMap anywhere... have I missed something ?...

POI icons
 

okay, well I figured out how to edit the poi database manually (since changing the name of a poi category always fails with a "problem updating category"). I'm putting it here in case anyone wants to know:
install sqlite (the command-line part of it) from application manager, then dump the binary sqlite database to a text file:
make a backup of the original db with:
then I edit /home/user/MyDocs/.documents/poi.db.text to my liking and put it back so that maemo mapper will use it:
note that I'm using sqlite and not sqlite3 here because I've still got the old os2006 installed (and I'm using an old version of maemo mapper still). Change sqlite commands to sqlite3 commands if you're using the newer one.

POI icons
 

here's what they look like:
http://www2.hawaii.edu/~mandrew/maem...ns/all-poi.png
And the tar:
poi.tar
Just copy it to your tablet and untar it from each map repository's dir:
cd /media/mmc1/maps/my-map-repository/
untar -x path/poi.tar
and it should work. You'll need to create a few of the poi categories to get them to work (ie, hospital, atm, airport, dumpster-diving, etc).

constructive comments on these icons and suggestions for new ones are welcome.

Re: Maemo Mapper v1.4 for 770/N800
 

Just intrigued as to what dumpster diving is....some quaint colonial practice?!

dumpster-diving
 

dumpster-diving is the art of going through someone else's discarded treasures (trash) to find working stuff or stuff you can fix and use. I've found computers, laptops, hard drives, monitors, TVs, couches, chairs, desks, etc.

Re: Maemo Mapper v1.4 for 770/N800
 

The OpenStreetMap repository is not downloaded via the "Download..." button. You can enter it manually, or if you don't mind losing your old repositories, you can use the "Default..." button, which reverts your entire repository list to the default (which is just the OpenStreetMap repo).

Re: Maemo Mapper v1.4 for 770/N800
 

Ouch... no thanks :-)
I'll enter it manually just to give it a try, although there doesn't seem to be much to see around where I live...

Re: Maemo Mapper v1.4 for 770/N800
 

Yeah, OpenStreetMap seems to be very Europe-centric, and even then, non-urban areas are hit-or-miss. Still, it's better than nothing (the old default), and hopefully it will improve.

Re: Maemo Mapper v1.4 for 770/N800
 

Can't seem to locate the URI though ?...

Re: Maemo Mapper v1.4 for 770/N800
 

Use one of the URL formats in the Maemo Mapper Repositories post.

Ooops, sorry, didn't remember to look there. Thanks !

create POI from address
 

I'm going on a trip next week, and I want to have as many POIs for the place I'm going (Kaua'i) as possible. I have a bunch of addresses for bank branches for my bank, grocery stores, kmart, costco, as well as campsites, etc. So I needed a quick way to generate POIs directly from street addresses. I created this patch against 1.4.4:
http://www2.hawaii.edu/~mandrew/maem...-against-1.4.4

It's basically just a copy of the download route function but makes the origin and destination the same and downloads the "route" to a temporary route (so as not to disturb the actual route), extracts the first non-zero lat/long and loads the poi_dialog so the user can name it, assign a poi category to it and create a description (which is pre-filled-in with the address).

It compiles and works fine on the old version of scratchbox I have installed, but I can't get an arm version to compile. I installed the newest scratchbox (1.0.7) and the i386 version compiles fine, but when I switch to the arm target, it complains about XML::Parser not being found (which IS installed).

here's what happens when I run ./configure:

anybody have any hints? I've only ever used scratchbox for maemo mapper and I've never tried to compile it for an arm target before this.

create POI from address
 

I finally did get it to compile for 770 with the old scratchbox. Here's the deb of maemo-mapper 1.4.4 (unmodified) for os2006 2.2006.39-14:
maemo-mapper_1.4.4-1_armel.deb

and here's the deb of my modified version (also for os2006 2.2006.39-14):
maemo-mapper_1.4.4-1-mza_armel.deb

Both work fine on my 770.

Here's a screenshot:

enjoy!

Re: Maemo Mapper v1.4 for 770/N800
 

Is anyone else having Mapper install issues with the new firmware? I did the install, it claims to have installed correctly, but it just doesn't run. Argh. Any help would be appreciated.

Thor

Re: Maemo Mapper v1.4 for 770/N800
 

Mapped works good on my freshly flashed N800, but not with 100% original repos. Have you tried "maemo-mapper" command from within the console? This should give a hint. Maybe there are some libraries missing, which dependencies were not resolved?

Re: Maemo Mapper v1.4 for 770/N800
 

Says "Segmentation fault".... not sure what that would mean.... bummer.

Re: Maemo Mapper v1.4 for 770/N800
 

Hmpf, could be related to many things :(
AFAIK some problems with the RAM...

EDIT: NULL-Pointers, bad memory allocation/rellocation for the the process, getting memory space without rights to write to it... and and and... bäh, the www is full of segfault error-messages :(

EDIT2: Did you have swap enabled? How's your memory "consumption" Normally the system handles that stuff automatically, perhaps something went wrong. Did you restart your N800?

map scale position
 

I wanted to put the scale on the lower right of my display (this precludes the ability to display other things there), so in maemo-mapper.c, I changed this line:
to this:
and voila.

Re: Maemo Mapper v1.4 for 770/N800
 

I had to do a backup/restore on my 800...now mapper displays an error that it can't open the POI database and the POI option is grayed out when holding down on a point on the map..any ideas? Seems to work in all other respects

Re: Maemo Mapper v1.4 for 770/N800
 

Can anyone please HELP!

I am running OS 2006 (Scirocco, not Gregale) and Maemo Mapper v1.35 on my n770. I have a Holux 240 GPS. Everything has been working splendidly until today when I was riding down I-95 in Florida following a route I had downloaded using my bluetooth cellphone. MaemoMapper suddenly shut itself down. When I tried to re-open it, it would start to load, then the "loading" dialog box disappeared without loading MM. When I tried to load it again, it loaded, then shut down suddenly again while trying to download the route again. This occured two or three times. Ultimately, I was unable to ever get MM to load again. What is worse, other apps fail to load now too. The n770 locks up and then either reboots itself or I have to put the cover on it to get it to shut down as the hard button won't cause it to shut down. Application manager won't load, and causes a reboot. Also, File Manager and Web browsing won't load and cause a reboot. I am really unhappy as my tablet is now pretty much useless! What to do??

thanks,
Neil

Re: Maemo Mapper v1.4 for 770/N800
 

More info as regards my earlier post:

I just tried to uninstall Maemo Mapper using the Application Manager. The App. Manager loads but immediately begins to "update". The update dialog box then freezes, and I get a reboot. When I tried clicked the installed apps box, it said that no apps are installed, which is of course incorrect.

Is a reflash my only option now?

Re: Maemo Mapper v1.4 for 770/N800
 

I read your other thread nspeer. I know this sucks. I resisted, too. But the best bet is to flash gregale. You can upgrade to the latest Maemo Mapper version that has a couple of nice new features. Sorry.

Re: Maemo Mapper v1.4 for 770/N800
 

(nspeer: same reply as in your other thread)

I can offer no suggestion as to how exactly Maemo Mapper could have caused this. :(

Maemo Mapper runs in the (protected) user account (as opposed to the privileged administrator account), just like any other program, so theoretically it is impossible for it (or other normal, non-OS programs) to destroy the rest of the operating system. At worst, programs can corrupt user data (i.e. in "Documents", "Videos", etc.), but application code (including the OS itself) should be protected from corruption by a rogue application. That is the Unix way, and it's why Windows has recently tried to follow suit with the introduction of Vista's security features.

So, either Maemo screwed up and allowed Maemo Mapper to do something it shouldn't have been able to do (and I'm not sure what that would be, unless you manually invoked the "Reset Bluetooth" feature), or Maemo screwed up and took Maemo Mapper down with it as collateral damage. The latter, more systemic option would also explain why none of your other applications work, including the OS programs like the Application Manager.

Unfortunately, neither of those explanations provides for a solution. The first thing I would try is properly switching off your device. It sounds like you haven't been able to do that (because "the hard button won't cause it to shut down"), so try either letting the battery run out or removing the battery entirely.

If you still have problems, I can think of no other solution for you than, as you suggested, re-flashing your device. If you continue to have problems after you re-flash, then it is a hardware problem for which (unfortunately) you must send the device to Nokia for repair.

Re: Maemo Mapper v1.4 for 770/N800
 

If you weren't using POI at all, just remove the POI database file (in the location indicated in the "POI" tab of the "Settings" dialog) and restart Maemo Mapper.

If you were using POI, and if you want to keep that POI, then you'll have to find another solution. Did you re-flash your N800 between backup and restore? Were you using an older version of Maemo Mapper before your backup/restore? If so, you may need to convert your database file from sqlite2 to sqlite3 format (search the forums on how to do this).

Re: Maemo Mapper v1.4 for 770/N800
 

Thanks for the help Gnuite..before any of that I did a backup/restore and somehow it restored the database file for POI's..why..who knows..but it works

Re: Maemo Mapper v1.4 for 770/N800
 

I made a patch so that maemo mapper will look for a file called "poi.jpg" if it can't find any other icon. This is so that if you don't like the purple square, you can make a different default.

patch against maemo mapper 1.4.4

And here's the icon I made for it (a blue "X"):

Re: Maemo Mapper v1.4 for 770/N800
 

Thanks for your reply.

One thing I have noticed. I was able to get to Control Panel > Memory. It shows device memory used as 31% at times and other times when I open Memory it shows 55%. Curious. before my problems started, device memory was at 3%.

So, what is hogging all my memory?

Re: Maemo Mapper v1.4 for 770/N800
 

When you say "Device Memory", do you mean the internal flash memory (as opposed to the external or internal memory cards)? If so, 3% seems rather low, so perhaps you are referring to your memory card's memory.

If you've set up Maemo Mapper to use your memory card, then it will use your memory card's disk space for maps. This might be using up your memory.

Or, if you have a "core-dumps" directory in your memory card, then it could be core files that are taking up memory, especially if programs have been crashing a lot since your problems started.

Re: Maemo Mapper v1.4 for 770/N800
 

Gnuite,
I really do mean device memory, I assume that's the internal flash memory of the 770. It always did read at 3%. So, now since my problems began, something is using A BUNCH more memory. There is lotsl of room left on my 1 gb memory card (and yes, MM is set up to store my maps on that card). I read another post on these boards where someone said their device got all messed up when they let the battery get too low. Thinking back, I was navigating with MM and downloading a map with my phone as a modem when MM shut down and all my problems began. I only had one bar on the battery meter at the time. So, maybe this was a contributing factor.

Anyway, it looks like I am going to flash to Gregale to hopefully fix my OS. This is not all bad as now I'll be able to upgrade to the latest Maemo Mapper (yeah!). Following Gnuite's advice in an earlier post, I want to "backup" my system files to my 1gb memory card using an Xterm command line and then restore it back once I've flashed. This is to preserve my GPE-Pim contacts and calander. Since my 770 has been constantly locking up and rebooting itself, I am worried that this might happen while I am in Xterm and that I'll BRICK my 770 if that happens. Is that possible? I mean, if I'm in Xterm, could whatever is causing my 770 to lock up and reboot still happen or is that not possible in Xterm?

Re: Maemo Mapper v1.4 for 770/N800
 

It's unlikely that a copy operation done in an xterm would do anything to cause your 770 to lock up, although in your situation, I suppose anything is possible.

In any case, you can't brick your 770 in xterm. No matter what happens, you'll be able to re-flash your device. It's actually extremely difficult to brick a 770 - the hardware pretty much has to be broken for that to happen.

Re: Maemo Mapper v1.4 for 770/N800
 

Gnuite,
thanks so much for your help. O.K. , after a copy in Xterm, I'm going to hold my breath and flash to Gregale today. Then, I am going to install the latest version of Maemo Mapper!

Re: Maemo Mapper v1.4 for 770/N800
 

Anybody having trouble connecting to the GPX server to download a route? What is the correct URL in the mapper app? I haven't changed any settings and was successful in the past in downloading routes

Re: Maemo Mapper v1.4 for 770/N800
 

I've not used Mapper much in the past, so this might not be relevant, but the gnuite.com server seems to be down at the moment, it might be related.

Re: Maemo Mapper v1.4 for 770/N800
 

OK, I'm back up now with Gregale and latest version of MM. I had to reformat my 1gb MMC and re-download all of my maps. I had a weird memory problem whereby the MMC showed 99% usage and all sorts of strange #'s like 700gb worth of stuff, etc. Now, even with 64mb allocated for Virtual Memory, the 770 is still slow as molasses most times and fails to render applets on the "homepage" and freezes and reboots itself often. It's acting like memory iis being hogged somewhere, but I can't figure out where. Load-App didn't reveal the culprit, just added to the slowness of the 770 by using even more memory.

As for MM, it is acting very erratically. Never had ANY problem with it with Scirroco and v1.35 (until the problems I've described in earlier posts above).
When I get a GPS fix, while sitting here in my office, the little blue dot "drifts" and the speedometer shows from 0 to 5 MPH with occasional leaps to 60,75,90 MPH! So, I start getting a red track laid down. Sometimes, it's just a small (several block) track, other times it's a long straight red line going for miles. Remember, I'm just sitting here! I should add that I'm only getting 3/11 satellites now.

Also, at times when I try to display full frame, the map is rendered with white borders on the bottom and right of the frame...not full frame at all.

Many times when I try to start MM, it fails to load and I have to try to start it a second time before it will load.

Any ideas what's up?

thanks,
Neil

Re: Maemo Mapper v1.4 for 770/N800
 

gnuite.com is down, so route downloads (and repository list downloads) will not work. I just installed a new router, and I don't think it handles my dynamic IP address very well (doesn't update dyndns with new IP addresses). I'm at work now, so I can't fix it, but I'll fix it soon.

Sorry for the inconvenience. :/

Re: Maemo Mapper v1.4 for 770/N800
 

Sounds like a hardware problem. Just to be sure, try re-flashing to the old firmware (scirocco) and see if you experience the same slowness.

Maemo Mapper gets all that data (location, speed) from your GPS receiver, so if Maemo Mapper says your speed is 90 MPH, then that's what your GPS receiver is telling Maemo Mapper that your speed is.

Maemo Mapper uses black to represent areas of the screen that do not have maps downloaded, so the only times you should see white are if they are in the map data itself, or if there is a bug in maemo that keeps Maemo Mapper from drawining in the areas.

Try running from the command line (xterm) and see if you get any errors.

All in all, if you just re-flashed and haven't installed much on your system, then it sounds like you have a hardware problem and need to see Nokia about getting it repaired or replaced.

Re: Maemo Mapper v1.4 for 770/N800
 

gnunite, what would it take to set up a mirror, if i was to volunteer my equipment? bandwidth requirements, server side components, sync functions?

you could then have MM iterate through the list of mirrors, should one fail, until it gets to a mirror that works...

Re: Maemo Mapper v1.4 for 770/N800
 

gnuite.com should be back up. Let me know if you have any more problems. Again, sorry for the inconvenience...

Re: Maemo Mapper v1.4 for 770/N800
 

Hmmm...sorry gnuite but still can't seem to download a route

Re: Maemo Mapper v1.4 for 770/N800
 

Some promblems when using WMS.

I'm running N800, OS Version is 3.2007.10-7 and MM version is 1.4.4-3 (downloaded from garage). Flite is version 1.3 and proj 4.4.9-3.

Maemo Mapper is running ok with downloaded map repostiories, but when I try to add my own WMS-repository, Maemo Mapper gives Segmentation fault after repository adding.

I have added following parameters at the begining of
/usr/share/proj/epsg file, I need ETRS-TM35FIN, epsg 3067 does not yet exist in proj 4.4.9-3 package.

# ETRS89 / ETRS-TM35FIN
<3067> +proj=utm +zone=35 +ellps=GRS80 +units=m +no_defs <>

Then I followed instructions available at
http://hoohol.ath.cx/public/index.ph...eMM-Extensions

I think examples are quite standard wms-queries except parameters for bounding box. When should I use %.2f or %.6f? What is the diffenrence?

After saving my own repository, at first try, MM crashes. And MM gives segmentation fault, every time when starting.

Any help or additionad documentation?
