Why this Pixhawk4 CRAZY in Ardupilot firm but NORMAL in PX4 firm?

[Kyomo_Jung]

Hi,

I have pixhawk4 crazy with barometer.

Regardless plane or copter, it is crazy with barometer first and after several minutes the HUD is also in mad as below.

I also tried Mavlink mirroring from MP to QGC but no difference

< At this try, the hud is calm >

But with PX4 Firm it’s normal as below

< At this try, this HUD is also calm >

< But alt is diffrecne between MP and QGC. It seems like MP doesn’t get alt data from PX4 >

Any comments would be very appreciated. Thanks in advance.

Because it is supposed to run the PX4 flight stack…
