Roadnav

[cycle_55]

I have the link right now but it freezes halfway through the map download and then just terminates. Have been unable to find any logs which might explain things. Thanks for the help and I will try this all again in a few days.

I'm having the same problem.  It's using the directory on the SD card that I linked to, so it's not a space issue.  I was having intermittent problems with my 'Net connection and thought that might be the problem, but it appears that this is not the case.

The very first time I ran the program it ran perfectly, except for the space issue. Since then it seems to be getting progressivly worse where now it will not run at all. It is not a space issue and I haven't noticed a problem with the internet connection. I will do a nand restore and start over and let you know.

after a nand restore and reinstall of roadnav I can not get it to run. I have tried both versions and it does the same thing with both, halfway through the map download it terminates on it's own and then if I try and start it again it just sits with an empty screen until it terminates once again after a few minutes. When I install Roadnav on my windows machine it doesn't seem to want to download a bunch of stuff and once running allows me to download maps individually. I will keep playing with it to see if I can make it work, thanks to dtruchan for compiling this for us. It will be very useful for me. Thanks again.

I reloaded everything and have found that I have to start Roadnav without an internet connection. Once it is loaded I can connect to the internet and let it download. It has now been sitting here downloading for three quarters of an hour and has not teminated itself yet. I hope this helps. I am using the alpha version. Thanks.

Just curious when it gives you directions is it able to read the street names or are the directions generic turn left,,,,

Do you have a swap file active?  One thing I noticed when I last tried Roadnav is that the system memory indicator kept climbing as it was downloading files and building maps.  I'm wondering if the problem is a memory issue.  It would be nice if the app supplied a more informative message than "Terminated."

I may look into setting up a swap file... I've got enough space on my SD card.  I don't know how that will affect performance, but it might only be needed when initially building the maps.

I think you are right that it is a memory issue. I also think it may apply only the first time when it is downloading and building maps. I have not tried setting up swap befor e so will have to figure out how. Thanks for the thoughts.

I don't know how long this thing takes to finish downloading, etc., but I'm now trying it with a 512MB swap partition.  I've already gotten much farther than I ever had previously.  It's looking good, so far!

[Drake01]

Well, I managed to get this running on Beta3.  To do so, I needed to create a swap partition.  I also needed to link /tmp to a directory on my SD card, since /tmp didn't have enough room for converting the downloaded maps.

It runs pretty slowly.  This might be due to the .roadnavdata directory, the /tmp directory, and the swap partition all being on my SD card.  I don't know how much bandwidth the SD interface on the Z provides, but I would guess it was overloaded.  Since my NIC's are both CF, I had to use SD for all the data.

I also learned that if you download a half dozen maps that include 2 or 3 complex counties (read: BIG maps) at the same time, it will really give your Zaurus a workout.  I felt like I was compiling a kernel!

I could not get Roadnav to run without the swap partition on, even after the maps were loaded and compiled.  After getting the maps set up, I disabled swap and tried to start up Roadnav.  After the memory use indicator climbed to the top, Roadnav died with the usual "Terminated" message.  (An interesting thing about the memory indicator is that when I start using swap heavily, it will blow out the top of the little red bar and start climbing up the green CPU bar. )

I guess when I receive the GPS unit I ordered I'll be able to test Roadnav for usability.  Right now, I'm not sure if it will be too slow to be useful.  This application was obviously intended for a laptop or something else with more power & memory than the PDA's and palmtops that I'm familiar with.

I have not tried a swap partition yet but as I said before when roadnav runs on my laptop the whole roadnav file is only 6.7MB so I am not sure why on the Z I have 70+MBs in the .roadnavdata file now and it is still not finished downloading. I will try an sd card as swap later and see how things go.

Unfortunately, it seems that roadnav is not optimized for running on a PDA, or even a Zaurus.  It's very feature-rich and does a nice job of rendering maps, but it seems to be too much of a hog to run effectively on my C1000.  

When I hooked up my GPS and tried driving, the map would update with my position... from about a mile back!  The icon that indicates my location on the map was about 30 to 60 seconds delayed.  The only time it seemd to accurately reflect my position was if I was stopped at a red light long enough for it to catch up.

I didn't have a chance to play with the settings too much, but I tried to turn off as many unnecessary features as possible.  Right now, I'm not confident that it will be possible to improve performance enough to get a realtime position, so roadnav may fail as an effective navigation aid on the Z.

When I get the chance, I'll try creating a swap partition on my microdrive.  Maybe that will provide a performance boost.
