Flightcontroller freezes after initialisation 3.1.5r2

[Floyer007]

I'd uploaded the new 3.1.5r2 firmware after deleting the eeprom at my "Multiwii and Megapirate AIO Flight Controller w/FTDI (ATmega 2560) V2.0".

Everything seems fine and the flight-controller starts, like in 3.0.1r4, with blinking LEDs.

But after this initialization the flight-controller hang on/ freezes and the LEDs turn off.
I can't connect via Mavlink (MissionPlaner) too.

It's completely useless with this firmware.

Little Update.
Uncommenting: //#define GPS_PROTOCOL GPS_PROTOCOL_UBLOX
Result: The Board doesn't freeze anymore.

I'd was used to define it.

So, no really bug.
Sorry for that

Strange problem, you could use the flashtool as-well. maybe this will work too.

As you wrote in you update the problem is resolved, please close this issue. thanks.
