Flashing firmware 3.1.5 with GPS support wobble and flip

[antonh1611]

Hi,
i had flashed the 3.1.5 version trough Flash tool (because i have problems flashing it with arduino - bootloop) without the GPS support, then tuned my quad perfectly, it was flying flawlessly, then i flashed the same settings with GPS support, then my quad at a faster left-right manouver starts wobbling and flips over. The board is Crius aio v2. I thought that was a vibration problem, and isolated the board from vibration, but the result was the same.
When i flashed 3.1.5 with GPS support, the GPS module was not connected. I have not tried it with the GPS module connected, but i do not see the connection between GPS and accelerometer.

Any other had a similar problem?

Should i open a separate ticket for the bootloop problem of the board after flashing it trough arduino?
the message on the apm planner goes: apm initializing
barometer calibrating

here is the reboot<
apm initializing
barometer calibrating

etc....... in loop

ok, just a small update:
the settings are:
RCTimer Crius aio v2
GPS Ublox
baudrate: 38400
Standard PWM a0....

this version wobbles,
but flashed the version with all the same settings except the baudrate: 19200
the quad fly perfectly again.
