Freerunner GPS not working
Hi, I'm unable to get a GPS fix on my Freerunner, S/N 8A8602882. I'm using a Linux om-gta02 2.6.24 #1 PREEMPT Wed Jul 30 11:56:48 CEST 2008 kernel with the stock 2007.2 that came with the Freerunner. After trying agpsui as descibed in the wiki for about an hour - without any satellites seen and trying the instructions given in http://lists.openmoko.org/pipermail/support/2008-July/000899.html I still don't get squad. Of course, tangogps and the lot don't work either. For those who understand NMEA, I'm seeing the following sequence in a apparently endless loop: $GPRMC,,V,,N*53 $GPVTG,N*30 $GPGGA,,0,00,99.99,,*48 $GPGSA,A,1,99.99,99.99,99.99*30 $GPGSV,1,1,00*79 $GPGLL,,V,N*64 $GPZDA,00,00*48 For as far I can see, the internal antenna connector is seated well. Any ideas? -- I have four children, and I want them to grow up in a country with a WORKING first amendment. -- Frank Zappa ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Re: Freerunner GPS not working
You say you're using the kernel that came with the phone? I'd try updating it, or removing your SD card.

Any ideas? Is it in a location that's known to have a usable GPS signal? I found that in some locations my Garmin sometimes couldn't get a fix either. If you can do it side by side testing would be useful. Have you tried without the SD card present? While the kernel you have gives reasonable performance with the SD present in my experience, testing without SD would help to narrow things down a bit. Do you have access to an external antenna? ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
