When I start the px4 on raspberry pi using navio2 I get some warning about default parameters are not set. I’ll attach a screenshot:
I see the following error in the QGC’s console:
[E] at qrc:/qml/SafetyComponent.qml:426 - “qrc:/qml/SafetyComponent.qml:426: TypeError: Cannot read property ‘value’ of null”
It seems like a QGC specific error, but Im wondering why these parameters are not present by default. Since if I set one of the missing parameters manually in the px4.config the warning message for that param goes away.
I set the following:
param set RTL_DESCEND_ALT 60
In the startup log it seems to be override the “default” value
RTL_DESCEND_ALT: curr: 30.0000 → new: 60.0000
And the the warning for that parameter is gone:
Also I observed that if I restart the application it looses all of the configuration/calibration I made before. Not sure if the root cause is the same or at least similar. But for me it look like the application cannot read / write the parameters from / to the filesystem.
Can you guide me which way I should look, or how to proceed to overcome this issue?
Thanks in advance!
