Hello !

My device is Nokia 3110c / v04.91 / 1GB Kingston microSD card and i using version 0.9.81 of TrekBuddy.

GPX problem:
In range 0.5 - 2 hours of navigating with tracklog enabled (GPX format, dt=60, ds=-1) i get error message like this:
Code:

Tracklog error java.io.IOException: only managed to write 66 of 1054 bytes to file

When problem occurs, free memory is always about 1MB. After dismiss this message, program works fine, but tracklog file have size 0 bytes. This problem is similar like this:

Pokus:
No, ja kdyz necham pri startu modulu zaznamenavat tracklog, pak mi po nekolika malo minutach naskoci na displej:Tracklog error java.io.IOException: only managed to write 206 of 834 bytes to file
Nevi nekdo kde je chyba a jak ji odstranit?

kruch:
...Bojim se, ze je problem ve firmwaru (nebo v karte) - takovouhle chybu jsem zatim na foru nevidel...

Pokus:
Vyzkousel jsem nahodne Settings - Misc - odznacit polozku forced GC) - za posledni 4 tracky bez problemu (mezi tim je i track asi hodinovej - cca 200kB)

I don't known czech language too much, but if i understand correctly, problem is in phone firmware or with memory card ? I have "forced GC" option unchecked, so this is not solution.
In addition, after this message, errors appears on filesystem. After repair errors with microsoft chkdsk, files converted from missing clusters are exactly GPX logs, ended with some garbage.So far, this problem is on Nokia 3109c and 3110c.

NMEA problem:
There is no errors during navigation with tracklog in NMEA format, but result file is corrupted and it's looks like:
Code:

(fragment of 4.5MB file)

Garbages are in many places of file (first occur after maybe 3 minuts of navigation) and are rest of files (i found png's for e.g.) that were previously on card.
Before every test, i format card in phone and rewrite TB data files, then check for errors with chkdsk. So, errors on card are not cause of problems. After all, program works excellent and i don't see any more issues.Please, check if it possible to make solution for this problem (tracklog is priority for me).

Best regards

After searching the Internet, i found that, there is a serious problem with Nokia 3110c (and probably 3109c) and any memory card (spontaneus restarts, problems with music library). I think it's main cause of my problems with tracklogging. Even phone firmware update, that i done (4.91 --> 6.60) doesn't help.
Finally, i set TB Data Folder to location on phone memory (file:///C:/predefgallery/predefphotos/TB) and after 1 hour testing with settings : GPX, dt=1, ds=-1 there is no any problem (beside limited place for storage; about 4.5MB in my case).
