The image available for Freerunner is very light and fast (didn't clock it, but perhaps just over half a minute for booting?). It is usable as phone since it's so responsive (it wakes up before the caller loses patience and hangs up). It leaves more than enough resources for (Tango)GPS. Only two things I have a problem with, are lack of capital letters (!) and GPRS in the default image (or anyway, I couldn't figure those out). Give it a try!

How can I solve this? I intended to give a hand, but I can't find the uSD with OpenWRT anymore to try it out. I downloaded and flashed anew, but now I do not even manage to get a connection to my Freerunner :-( Perhaps my problem at the moment is similar to yours but the other way around; my network here is in the 192.168.1.x range, and I might have addedd incorrect routes to 192.168.1.1 that the Freerunner occupies now. As suggested in another reply, what does ip route say? ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Freerunner - small and fast distribution only for GPS
Hello, does someone know a small distribution which is only made for GPS usage? For outdoor holydays it would be nice to have such a distro. There is no need for using the GSM, blootooth, wifi, acceleration sensor and so on. It should only be fast at booting and should have a small energy consumption. For the application I'm thinking of something like tangogps. It should be able to show the position on a map and log a track. Ok, if there is not such a distro, would it possible to build it? My programming skills are very small for this topic so I don't know where to start. A little help from you would be nice. :-) Thanks for reading and for any hint to the right direction. :-) Greetings, Carsten ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

I haven't really looked at it, but perhaps the OpenTom project has something to offer that could be easily adapted to the FreeRunner in the case that you don't come across anything else: http://www.opentom.org/ They're mainly focused on documenting how to get a Linux OS other than the stock TomTom firmware installed onto TomTom hardware, but maybe there is some subset of that community that's interested in using their GPS units as a GPS units, too. :) -- Don't be afraid to ask (λf.((λx.xx) (λr.f(rr. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
