Mission Planner Vs APM Planner

ArduCopter Copter 3.2

One quick question. Does mission planner and APM planner use different firmware? Reason I ask is I used Mission Planner to configure my 2.6 board and all is good. When I use APM planner to connect to the board GPS will not lock onto my location on both windows and Linux versions.

Thanks

The firmware is the same as installed by mission planner
