What were you trying to do that didn't work?
The gnss dev is outputting the GNRMC and GNGGA message but the ts2phc log only shows the GNRMC message.

added a comment - The message following RMC is ignored due a missing reset of the parser. This is not a problem if there are non-RMC messages, but if the receiver is configured to generate RMC messages only, every other will be ignored.
Fix submitted to upstream:
