I seem to have got it working, although I’m not too sure how.
It finally got a fix when I was inside playing around with different gllin options. I tried the "cold" option (cold start) and then “-sim“ (not using simulator) 5min after that it was getting fixes. Although I can't be sure the different options had anything to do with getting it to work and I have no idea why it would have been using the ‘simulator’ in the first place since I was using a normal buildhost image and standard gllin ipk
In any case, it's working now so i'm happy :) Thanks for your help Ben. Ben Wilson wrote:

Are you in a city or somewhere else where you'd have a lot of obstructions? You need line-of-sight with 4 (preferably more) to get a lock.

I followed the instructions here http://lists.openmoko.org/pipermail/community/2007-November/011916.html to get gllin installed and i do get the $GPxxx info, it just never locks. (Always A1). I get the date on the $GPRMC line which i've been told means the gps receiver has found at least one satellite.I've tried it on different kernel/rootfs images and i get the same thing.Does anybody else have this problem?
