No, that is definitely not the case. But occasionally I have seen this behaviour too on my FR, yet never on the Neo1973s. One interesting observation I made is that my FR has in the beginning often a GPS time offset 15 seconds into the future. It does so even if I feed the time by AGPS. It takes 10-15 minutes until this is corrected by the chip. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: GTA02 GPS rework for SD card interference issue
2008/7/24 Al Johnson [EMAIL PROTECTED]: fixed a long way back in the route. I didn't have a tile cached for the area I had walked into. When I zoomed out to a scale where I did have a tile cached it redrew the track, this time following the route I had walked without jumping. Actually if you do not have the area cached, it will just stay at the previous zoom level map tile wise if you zoom in and draw a new trace line on top of the old one. Ie. it is just messing up the display. -Timo ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

well from what Andy says they have found a software fix which - keeps good SD card perf (for cards tested so far) - doesn't degrade gps signal the software fix will be in the new kernel very soon and - switches off SD clock when not needed - reduces the drive strength of the SD signal when on so looks to me that the hardware kids can go ahead if they want to but not proved necessary right now... jw ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Re: GTA02 GPS rework for SD card interference issue
Hi guys, as I wrote before ( but the message did apparently not hit the list since I used a different email address ) I had the hardware fix applied on friday but used a 0603 cap instead, which fit quite nicely. After further testing I can only congratulate the OM-team for their quick and easy fix: whether inside at the window, in a moving train or in narrow streets, the FR is aquiring a Fix consistenly within about 120s from cold start under the most difficult conditions, and of course even faster at consecutive tries ( warm start ). Under normal conditions, a TTFF of 40s seems to be the maximum needed even for a cold start, which in my opinion is exceptionally good! The SD-Card (4GB) still works as expected by this RF only fix, and there is no need to unmount it ... Btw, this was all done with the mwester-andy kernel from 080716... Big thumbs up to everyone at OM, now let the mapping begin ;-) Stefan On Fri, Jul 18, 2008 at 1:26 PM, Stefan Fröbe [EMAIL PROTECTED] wrote: Great work, and I can confirm this to be working just fine !!! That's an advantage of working in a company in the semiconductor business: enough people with the skills and tools able to try this modification out on a lunchbreak - now I get a TTFF from cold boot of 150s under most difficult conditions: Clouds / Mist, and high buildings on two sides. The previous software-only improvements were of mixed results: only once did a fix occur, and by far not as fast as the 34s I got without SD-Card. Will keep you updated on further results this weekend, but so far it is great news to see a fix this quickly!
