Narrative:
While flying the RNAV the glide path failed to activate; reverted to the LNAV minimums (900 ft MSL). After descending to about 980 ft MSL; and having broken out of the clouds at 1100 ft MSL received an altitude warning from the tower. Confirmed altitude and went to; and maintained 1000 ft MSL; and reported that fact to tower. Had runway in sight at the time and proceeded with a normal landing. While I believe that I operated consistent with the requirements for the LNAV approach; I did step down rapidly after 'zzzzz' intersection and I suspect that the tower was expecting an lpv approach. In hindsight I should have reduced altitude at a slower rate. I will also determine why the glide path did not activate.
