Navit will not work on a TomTom One Device

[me.yahoo.com/a/jya23di6w_0a00d6zazcw88xiiakhiu91aw-#78152]

Hello,

I have a TomTom? One (V2) Device an would use it to run navit.

I have installed the precompiled Version 4300 as on ​http://wiki.navit-project.org/index.php/Navit_on_TomTom descripted.

I can start navit an play around, all works fine _without_ a _valid_ GPS-Signal.

When I have a valid GPS-Signal, then the application will be killed after 2 or 3 minutes from the watchdog and the device will be reboot.

I have modified the startup-script and the watchdog feeding. I have two logfiles: the normal log and the wrapper-log.

Could you provide a more detailed navit-log file? I recommend increasing the debug levels for "vehicle_file" and "navit" in your xml config file (which should be navit/share/config/tomtom320.xml on your TomTom?) from "0" to "5". You can find the debug level settings close to the start of the file (search for '<debug name="'). The generated output will be quite large, so you better post only the last ~20-50 lines of the file.

Hello,

I have change the debug-level for navit and vehicle_file from 0 to 5 and running navit on my TomTom?. It's was very slow, but navit was not killed by watchdog. After 30 minutes I have regular exit navit.

From the logfile navit.log I have added the last 350 lines and the navit-wrapper.log with timestamps and loads. Maybe it's helps.

Sorry for my bad English.

Hm... This is strange. The log file looks perfectly fine to me, I can't see any problems - so I have no clue what could be causing the crash. The only thing I could imagine is that Navit consumes a lot of CPU time and thus "blocks" the wrapper script, so it cannot trigger the watchdog before its period expires.

Hello,

I repeated the test and wait until the application is killed by the watchdog. It took 1 hour min 30. My TomTom? had a good GPS signal and was not moved.

I will attach the log wrapper completely. From navit-log only the last 100 lines. Strangely, the time difference is between two logs exactly 2 hours. Using the navit-log UTC?

Yes, the timestamps in the navit log are UTC.

Again, the navit log looks perfectly fine... The same is true for the wrapper log. No increase in CPU load, no error messages, no unexpected data... Everything looks fine, there are no hints what may be causing the crash.

So here's another idea how we might get some hint what's happening: Set the debug levels back to "0" in the config file (these won't help us anyway), and set the debug level of "segv" to "1". When navit crashes, this should use the GNU debugger (gdb, included in the Navit on TomTom? binary package) to print a "stack trace", which should appear in the log file. The stack trace can show what exactly navit is doing when the crash occurs. I hope it works...

[me.yahoo.com/a/jya23di6w_0a00d6zazcw88xiiakhiu91aw-#78152]

Ok, I have changed the logging for navit and vehicle_file to 0 and segv to 1. Then I have started my TT and wait for a long time for a valid GPS-Signal. Then I have started navit and 2 minutes later was it's kills by watchdog.

I will added the navit.log and navit-wrapper.log, but the navit.log contains no stack trace. :-(

I wondering about the load in the navit-wrapper.log: it rises to over 3. With logging-level 5 for navit and vehicle_file the maximum value was about 2 in the last and the last 5 minutes.
