For those that follow the devel and commitlog lists, there was a patch submitted by Andy Green @ Openmoko on the 13th suggesting that an increase in voltage to the GPS workings might help. I haven't tried this myself.
The note attached said: "GPS internal antenna issue appears to respond positively to cranking RF_3V to 3.6V from 3.0V." Perhaps Torfinn's last Email was right: it may not be an EMC problem but a lack of voltage? -id thomasg wrote: > Hi ppl, > > I write this to community, not to devel or owners because everyone > should know: > _sbeh_, one of the people in #neo1973-germany IRC-channel found the > reason for the GPS problems. > The problem only occurs if a SD card is set in.
