Impossible to select the right airframe

[Pauloledes]

Hi everyone,

I am currently facing an issue that I have never had before. The problem appears when I try to select an airframe for my Intel AERO Drone. In reality I have two problems.

The first one is that QGroundControl (v.3.4.0) does not offer me the possibility to select the right airframe for my drone so I have to select one I think is the closest one of my real airframe. It is weird because I work with an other student who is able to select the right Airframe. The only difference between us is that he installed QGC on Windows whereas I installed it on Linux Ubuntu. Here is a picture of which airframes I can choose.

The second one is that QGC seems not to save the airframe I select. That is what my interface looks like after I selected a Generic Quadrotor X airframe.

It is a bit annoying since I can not do the other calibration properly because QGroundControl reacts like I never told it which airframe I am using.Then it does not know if it is connected to a Quadrotor or a plane for example.

Here are the full informations of the versions I am using :

The firmware is Px4.

BIOS_VERSION = AERO-01.00.13
OS_VERSION = Poky Aero (Intel Aero Linux Distro) 1.6.1 (pyro)"
AIRMAP_VERSION = 0xc2
AeroFC firmware version = 1.6.5

QGroundControl 3.4.0

Most likely your cached airframe meta data is out of whack. Delete the PX4AirframeFactMetaData.xml in your ~/.config/QGroundControl.org directory. Boot QGC. Should show up.

@LorenzMeier This seems to happen a bunch. Not sure that caching the airframe xml from flashing is such a great idea. That version seems to be screwed up sometimes, whereas the version in QGC is correct. But the cached version takes precedence so users get stuck.

Thank you for your help @DonLakeFlyer, now it works !

I was getting the same issue but after many tests when using QGC v3.4.4 and pixhawk firmware v1.5.5
Then when I switched firmware to v1.8.2, then the issue was fixed.
