I'm using FSO 4.1 , and have a similar problem. Enabling debug on framework 
gives messages that suggest it is sending NMEA data when frameworkd is 
expexting UBX data. There's a curious message in the logs - 'exception 
0x80000040 was trapped' .The GPS clearly has power. Here's some of the log:

followed by some almenac data and then this interesting snippet:
